Marketing communications performance indicators are quantifiable metrics that measure how effectively your promotional campaigns generate awareness, engagement, conversions, and revenue across channels like email, social media, paid ads, and content marketing. Tracking the right indicators separates high-performing marketing teams from those wasting budget on campaigns that look busy but produce no measurable business outcome. This guide covers 27 marketing communications performance indicators organized by funnel stage, with formulas, benchmarks, and a framework for selecting the KPIs that matter most to your business.

What Are Marketing Communications Performance Indicators?

Quick Answer: Marketing communications performance indicators are measurable values that evaluate the success of promotional campaigns in reaching, engaging, and converting target audiences. These indicators are organized across the marketing funnel, from awareness through retention, and help marketers allocate budget, optimize messaging, and demonstrate ROI to stakeholders.

Marketing communications performance indicators (also called marketing KPIs) quantify the results of every campaign, channel, and tactic your team deploys. Unlike general business metrics such as total revenue or profit margin, these indicators focus specifically on the performance of your communications: emails, social media posts, paid advertisements, content marketing assets, and PR campaigns.

The distinction between a KPI and a metric matters. A metric is any data point you can measure. A KPI is a metric that directly ties to a strategic business objective. For example, your email platform may report 50 different data points, but only the 3 to 5 metrics that connect to your quarterly goals qualify as KPIs.

According to the HubSpot 2026 State of Marketing Report, lead-to-customer conversion is the second most important KPI for marketers across businesses of all sizes. The report also found that for B2C brands, email marketing delivers the highest ROI of any channel.

The sections below organize 27 indicators into four funnel stages: awareness, engagement, conversion, and retention. Each indicator includes its formula, what it measures, and when to use it.

Top-of-Funnel Marketing Communications Performance Indicators (Awareness)

Top-of-funnel marketing communications performance indicators measure how many people see and recognize your brand messaging. These indicators answer one question: is your communication reaching the intended audience?

1. Impressions

Impressions measure the total number of times your content is displayed to a user, regardless of whether the user interacts with it. One user who sees the same ad three times counts as three impressions.

Formula: Total displays of content across all placements

Impressions are most useful for brand awareness campaigns, paid media reporting, and social media reach analysis. A high impression count with a low click-through rate signals that the creative or targeting needs improvement.

2. Reach

Reach measures the number of unique users who see your content at least once. Unlike impressions, reach counts each person only once regardless of how many times the content was displayed.

Formula: Unique users exposed to content / Total target audience x 100

According to research from Edelman, reach metrics are fundamental to evaluating message penetration in PR and communications campaigns. The key distinction from impressions is that reach tells you audience breadth, while impressions tell you message frequency.

3. Share of Voice (SOV)

Share of voice measures your brand’s visibility relative to competitors within a specific channel, topic, or industry. SOV applies to paid media, organic search, social media mentions, and PR coverage.

Formula: Your brand mentions / Total market mentions x 100

A 2025 analysis from the Institute of Practitioners in Advertising (IPA) found that brands whose share of voice exceeds their share of market tend to grow, while brands with SOV below their market share tend to shrink. This makes SOV a leading indicator of long-term market position.

4. Brand Awareness Rate

Brand awareness rate measures the percentage of your target market that can identify or recall your brand. This indicator is typically measured through surveys, polls, or brand tracking studies.

Formula: Respondents who recognize your brand / Total survey respondents x 100

Brand awareness is a lagging indicator that moves slowly. It is most useful for companies running sustained awareness campaigns over 6 to 12 months or longer.

5. Traffic by Source

Traffic by source breaks down your website visitors by the channel that brought them: organic search, paid search, social media, email, direct, and referral. This indicator reveals which communication channels drive the most visitors.

Formula: Visits from specific channel / Total visits x 100

In 2025, organic search generated the highest ROI for B2B brands, while email marketing generated the highest ROI for B2C brands, according to the HubSpot State of Marketing Report. Tracking traffic by source helps you identify which channels deserve more investment and which are underperforming.

Traffic by SourceChannel-level visitor breakdownBudget allocation decisions

Mid-Funnel Marketing Communications Performance Indicators (Engagement)

Mid-funnel indicators measure how your audience interacts with your communications after initial exposure. These metrics reveal whether your messaging resonates and whether prospects are moving closer to a conversion event.

6. Click-Through Rate (CTR)

Click-through rate measures the percentage of people who click on a link in your communication after seeing it. CTR applies to email campaigns, paid ads, social media posts, and search results.

Formula: Clicks / Impressions (or Delivered emails) x 100

The average CTR for search advertising in 2025 was 6.66% across all industries, according to Wordstream benchmarks. For email marketing, the average click rate in 2025 was 2.09%, according to MailerLite’s benchmark report covering 3.6 million campaigns.

7. Email Open Rate

Email open rate measures the percentage of delivered emails that recipients open. This has historically been one of the most tracked email marketing KPIs, but its reliability has decreased since Apple introduced Mail Privacy Protection (MPP) in September 2021.

Formula: Emails opened / Emails delivered x 100

The average email open rate in 2025 was 43.46%, up from 42.35% in 2024, according to MailerLite. However, Apple MPP automatically pre-loads email content for Apple Mail users, inflating open rates by approximately 18 percentage points. Since Apple Mail accounts for 46% of email clients, marketers should treat open rate as a directional metric and prioritize click-based indicators for campaign evaluation. 

8. Social Media Engagement Rate

Social media engagement rate measures the total interactions (likes, comments, shares, saves) a post receives relative to the number of people who saw it or follow the account.

Formula: Total interactions / Total reach (or followers) x 100

Engagement rate benchmarks vary significantly by platform. Instagram engagement rates average 1.5% to 3.0% for business accounts, while LinkedIn posts average 2.0% to 4.0% for company pages, according to 2025 data from Sprout Social.

9. Bounce Rate

Bounce rate measures the percentage of website visitors who leave after viewing only one page without taking any further action. A high bounce rate on a landing page suggests a mismatch between the communication that drove traffic and the page content.

Formula: Single-page sessions / Total sessions x 100

According to Contentsquare’s 2025 Digital Experience Benchmark, the average bounce rate across industries is 47%. Landing pages connected to email campaigns typically have lower bounce rates (25% to 40%) because the traffic is pre-qualified.

10. Time on Page (Dwell Time)

Time on page measures how long a visitor spends on a specific page before navigating away. This indicator reflects content quality and relevance.

Formula: Automatically tracked by analytics platforms (GA4)

Pages with dwell time under 30 seconds indicate the content did not meet the visitor’s expectation. Pages with dwell time over 2 minutes indicate strong content engagement. For blog posts and long-form content, average dwell time of 3 to 5 minutes is a strong benchmark.

11. Email List Growth Rate

Email list growth rate measures how quickly your subscriber list is expanding after accounting for unsubscribes and bounces.

Formula: (New subscribers – Unsubscribes – Bounces) / Total subscribers x 100

A healthy email list grows at 2% to 5% per month. Lists that shrink faster than they grow indicate a problem with acquisition, content quality, or sending frequency — see our guide to email list management for the full framework on building, growing, and maintaining a healthy list. Our List Hygiene feature automatically removes invalid addresses, spam traps, and known complainers during import, which keeps your list growth rate accurate and your sender reputation protected. 

12. Email Forwarding and Sharing Rate

Email forwarding rate measures the percentage of recipients who forward your email or click a “share this” button. This indicator reveals how valuable your content is to subscribers.

Formula: Forwards or shares / Total delivered emails x 100

A forwarding rate above 0.5% is considered strong. This metric is a leading indicator of organic list growth because forwarded emails often result in new subscribers.

Mid-Funnel Performance Indicators Summary

IndicatorWhat It Measures2025 Benchmark
Click-Through Rate (Email)Clicks per delivered email2.09% average
Email Open RateOpens per delivered email43.46% (inflated by Apple MPP)
Social Media EngagementInteractions per impression1.5% to 4.0% by platform
Bounce Rate (Website)Single-page exits47% average
Time on PageContent engagement depth3 to 5 min for long-form
Email List Growth RateNet subscriber additions2% to 5% monthly
Email Forwarding RateContent shareability0.5%+ is strong

Bottom-of-Funnel Marketing Communications Performance Indicators (Conversion)

Bottom-of-funnel indicators tie your marketing communications directly to financial business outcomes. These are the KPIs that stakeholders and executives care about most because they show the direct revenue impact of your campaigns.

13. Conversion Rate

Conversion rate measures the percentage of targeted prospects who complete a desired action such as making a purchase, filling out a form, signing up for a trial, or downloading a resource.

Formula: Conversions / Total visitors (or recipients) x 100

The average conversion rate across all ecommerce sites was under 2% in 2025, according to Statista. Email marketing campaigns typically convert at 2.9% to 3.3% for retail and fashion, according to 2025 industry benchmarks. Segmented email campaigns convert at significantly higher rates because the message matches the recipient’s intent.

14. Cost per Lead (CPL)

Cost per lead measures the total amount spent on a campaign divided by the number of new leads generated. CPL helps marketers compare the efficiency of different channels and campaigns.

Formula: Total campaign cost / Number of leads generated

CPL varies dramatically by industry. B2B SaaS companies typically see CPL between $50 and $200, while ecommerce brands may see CPL between $5 and $30. Email marketing consistently produces one of the lowest CPLs across all channels because the marginal cost of sending an additional email is near zero.

15. Customer Acquisition Cost (CAC)

Customer acquisition cost measures the total cost to acquire one new paying customer, including all marketing and sales expenses.

Formula: Total marketing + sales costs / Number of new customers acquired

CAC is one of the most important marketing communications performance indicators because it directly affects profitability. A healthy CAC is one that can be recovered within the first purchase or within 3 to 6 months of the customer relationship. Companies with high CAC relative to customer lifetime value are spending unsustainably.

16. Return on Investment (ROI)

Return on investment measures the net profit generated by a marketing campaign relative to its total cost.

Formula: (Revenue from campaign – Campaign cost) / Campaign cost x 100

Email marketing consistently delivers the highest ROI of any digital marketing channel. The Data & Marketing Association reports an average ROI of $36 to $42 for every $1 spent on email marketing, depending on industry and campaign type. The highest-ROI sends within email tend to be automated email sequences triggered by subscriber behavior, which consistently outperform broadcast campaigns on revenue per email. 

17. Revenue per Email (RPE)

Revenue per email measures the total revenue generated by an email campaign divided by the number of emails delivered. This indicator is specific to email marketing and provides a direct revenue-to-send ratio.

Formula: Total campaign revenue / Emails delivered

RPE is most useful for ecommerce and direct-response marketers who can attribute sales directly to email campaigns. Emercury’s ECPM Reporting tracks revenue per subscriber, giving marketers visibility into the monetary value of every contact on their list.

18. Marketing Qualified Leads (MQLs)

Marketing qualified leads are prospects who have shown enough interest through marketing communications to be considered ready for sales follow-up. MQL criteria are defined by behavior such as visiting a pricing page, downloading a whitepaper, or attending a webinar.

Formula: Number of leads meeting MQL criteria within a defined period

MQLs bridge the gap between marketing activity and sales pipeline. The MQL-to-SQL conversion rate benchmarks at 13% for B2B companies, according to research from Forrester.

19. Sales Qualified Leads (SQLs)

Sales qualified leads are MQLs that the sales team has vetted and confirmed as genuine purchase opportunities.

Formula: Number of MQLs accepted by sales within a defined period

The MQL-to-SQL handoff is where many marketing communications programs break down. Clear definitions and scoring criteria prevent friction between marketing and sales teams.

20. Campaign ROI by Channel

Campaign ROI by channel breaks down return on investment for each communication channel independently: email, paid search, social media, content marketing, and events.

Formula: (Channel revenue – Channel cost) / Channel cost x 100

This indicator reveals which channels produce the highest return and which channels underperform relative to their cost. In 2025, B2C brands reported that email marketing, paid social, and content marketing delivered the highest ROI, in that order, according to the HubSpot State of Marketing Report.

Retention and Loyalty Performance Indicators

Retention indicators measure how well your marketing communications maintain customer relationships after the initial conversion. Acquiring a new customer costs 5 to 7 times more than retaining an existing one, which makes retention KPIs critical for long-term profitability.

21. Customer Lifetime Value (CLTV)

Customer lifetime value measures the total revenue a business can expect from a single customer account over the duration of the relationship.

Formula: Average purchase value x Purchase frequency x Customer lifespan

CLTV is the counterbalance to CAC. A healthy business maintains a CLTV-to-CAC ratio of 3:1 or higher, meaning each customer generates at least three times more revenue than the cost to acquire that customer. Email nurture campaigns, loyalty programs, and re-engagement sequences all contribute to increasing CLTV.

22. Customer Retention Rate

Customer retention rate measures the percentage of customers who continue to do business with you over a specific period.

Formula: (Customers at end of period – New customers) / Customers at start of period x 100

Research from Bain & Company found that increasing customer retention by just 5% can increase profits by 25% to 95%. Email marketing automation, particularly post-purchase sequences, win-back campaigns, and loyalty communications, directly influences retention rates.

23. Net Promoter Score (NPS)

Net Promoter Score measures customer loyalty by asking one question: “How likely are you to recommend our brand to a friend or colleague?” Respondents score on a 0-to-10 scale and are classified as Promoters (9-10), Passives (7-8), or Detractors (0-6).

Formula: % Promoters – % Detractors

NPS benchmarks vary by industry. SaaS companies average an NPS of 30 to 40, while ecommerce companies average 45 to 55. NPS surveys are commonly deployed via email, making email marketing platforms a natural distribution channel for this indicator.

24. Email Unsubscribe Rate

Email unsubscribe rate measures the percentage of recipients who opt out of your email list after receiving a campaign.

Formula: Unsubscribes / Emails delivered x 100

The average unsubscribe rate across industries in 2025 was 0.15%, according to Brevo’s benchmark report covering 44 billion emails. An unsubscribe rate consistently above 0.5% signals content misalignment, excessive sending frequency, or poor list segmentation.

25. Churn Rate

Churn rate measures the percentage of customers who stop doing business with you during a given period. For subscription businesses, churn rate is the inverse of retention rate.

Formula: Customers lost during period / Customers at start of period x 100

Monthly churn rates vary by industry: SaaS averages 3% to 8%, while ecommerce subscription services average 5% to 10%. Automated re-engagement and win-back email campaigns are among the most effective tools to reduce churn.

26. Repeat Purchase Rate

Repeat purchase rate measures the percentage of customers who make more than one purchase within a defined period.

Formula: Customers with 2+ purchases / Total customers x 100

A repeat purchase rate above 30% is considered strong for ecommerce businesses. Post-purchase email sequences, product recommendation emails, and loyalty reward communications all drive repeat purchases.

27. Email Deliverability Rate

Email deliverability rate measures the percentage of sent emails that successfully reach the recipient’s inbox rather than being filtered to spam or bounced.

Formula: Emails delivered to inbox / Total emails sent x 100

Deliverability is the foundation of every email marketing performance indicator. If your emails do not reach the inbox, open rates, click rates, and conversions all suffer. Industry benchmarks target a deliverability rate of 95% or higher, and one of the highest-leverage practices for getting there is consistent email suppression list management — keeping unsubscribes, hard bounces, and complainers permanently out of your sending pool. Our deliverability-first approach includes built-in List Hygiene, domain authentication support, sender reputation monitoring, and a DMARC Record Generator to help you maintain inbox placement. 

How to Select the Right Marketing Communications Performance Indicators

Quick Answer: Selecting the right marketing communications performance indicators requires aligning metrics with your business goals, funnel stage, and available data. Start with your primary business objective, then choose one lead indicator and one lag indicator per funnel stage to create a concise, actionable dashboard.

Not every indicator listed above belongs on your dashboard. Tracking too many KPIs creates noise and prevents action. The Reddit marketing community consistently reports that clients prefer simplicity: 45% of agency leaders say their clients only care about 1 to 5 KPIs.

Follow this 4-step selection framework:

  1. Define your business objective. Are you trying to grow brand awareness, generate leads, increase sales, or reduce churn? Your objective determines which funnel stage matters most.
  2. Choose one lead indicator per funnel stage. Lead indicators predict future results. Examples: impressions predict reach, CTR predicts conversions, NPS predicts retention.
  3. Choose one lag indicator per funnel stage. Lag indicators confirm past results. Examples: conversion rate confirms campaign success, CLTV confirms retention program effectiveness.
  4. Set benchmarks using industry data. Use the benchmark tables in this article as starting points, then adjust based on your historical performance.

This framework gives you 4 to 8 KPIs that tell a complete performance story without overwhelming stakeholders with data they cannot act on.

How to Report Marketing Communications Performance Indicators to Stakeholders

Quick Answer: Reporting marketing communications KPIs to stakeholders requires connecting each metric to a business outcome, using data storytelling to explain what changed and why, and keeping reports focused on 3 to 5 actionable insights rather than raw data dumps.

Stakeholders do not want spreadsheets with 50 metrics. They want answers to three questions: What worked? What did not work? What should we change?

Structure your KPI reports using this format:

  1. Executive summary. Start with the single most important result of the reporting period, expressed in revenue or pipeline impact.
  2. KPI scorecard. Show 3 to 5 KPIs with current performance, benchmark comparison, and trend direction (up, down, flat).
  3. Analysis. Explain why each KPI moved. As one Reddit user noted, “nobody cares if X goes up 15%, but if you can add depth like we saw this 15% growth because of X based on Y data, that is closer to actionable information.”
  4. Recommendations. List 2 to 3 specific actions for the next reporting period.

Keep the report concise. Include detailed analysis as an appendix for stakeholders who want to explore further.

Email Marketing Performance Indicators and How Emercury Tracks Them

Common Mistakes When Tracking Marketing Communications Performance Indicators

Quick Answer: The most common mistakes include tracking too many metrics without acting on them, relying on vanity metrics like impressions without connecting them to revenue, comparing KPIs across incompatible channels, and failing to account for data quality issues like Apple MPP inflation on email open rates.

Avoid these 5 mistakes that undermine your KPI tracking:

  1. Tracking everything, acting on nothing. More data does not equal better decisions. Limit your active dashboard to 4 to 8 KPIs and review them on a consistent cadence (weekly for campaign metrics, monthly for strategic metrics).
  2. Relying on open rate as a primary email KPI. Since Apple MPP launched in September 2021, email open rates have been inflated by approximately 18 percentage points. Use click-through rate and conversion rate as your primary email engagement indicators instead.
  3. Comparing KPIs across incompatible channels. A 2% CTR on email is strong. A 2% CTR on paid search may be below average. Always use channel-specific benchmarks when evaluating performance.
  4. Ignoring data storytelling. Raw numbers without context are not useful. A 15% increase in conversions means nothing to a stakeholder unless you explain what caused the increase and whether the trend is sustainable.
  5. Setting KPI targets without historical baselines. Your first quarter of tracking should focus on establishing baselines, not hitting targets. Use the benchmark data in this article as a starting point, then calibrate targets based on your actual performance data.

Conclusion

Marketing communications performance indicators give your team the data needed to optimize campaigns, allocate budget effectively, and demonstrate measurable business impact. The 27 indicators in this guide cover every stage of the marketing funnel, from awareness metrics like impressions and reach through conversion metrics like CAC and ROI, down to retention metrics like CLTV and NPS.

The key to effective KPI tracking is not tracking more indicators. It is selecting fewer, more meaningful indicators that connect directly to your business objectives and acting on the data consistently.

For email marketers, the performance indicators that matter most in 2026 are click-through rate, conversion rate, revenue per email, deliverability rate, and list growth rate. These five metrics tell a complete story about email program health and revenue contribution.

Our platform is built for performance email marketers who need real-time visibility into these marketing communications performance indicators. With Smart Segments, Content Scoring, A/B split campaigns, and campaign-level reporting available across plans — plus ECPM Reporting on the Scale tier — we give you the data to make every campaign more profitable.

Frequently Asked Questions

1. What Are Marketing Communications Performance Indicators?

Marketing communications performance indicators are measurable values used to evaluate how effectively promotional campaigns reach, engage, and convert target audiences across communication channels. These indicators include metrics like click-through rate, conversion rate, customer acquisition cost, and return on investment. Marketers use these KPIs to allocate budget, optimize messaging, and report campaign results to stakeholders.

2. What Is the Difference Between a Marketing KPI and a Marketing Metric?

A marketing metric is any measurable data point, such as page views or email sends. A marketing KPI is a metric that directly connects to a strategic business objective. For example, total emails sent is a metric, while email conversion rate is a KPI because it ties directly to revenue goals. Every KPI is a metric, but not every metric qualifies as a KPI.

3. Which Marketing Communications KPIs Matter Most for Email Marketing?

The five most important email marketing KPIs are click-through rate, conversion rate, deliverability rate, revenue per email, and list growth rate. Open rate is commonly tracked but has been unreliable since Apple Mail Privacy Protection launched in 2021, inflating reported open rates by approximately 18 percentage points across the industry.

4. How Many Marketing KPIs Should I Track at Once?

Most marketing teams should track 4 to 8 active KPIs organized by funnel stage. Research shows that 45% of agency leaders report their clients are interested in only 1 to 5 KPIs. Tracking too many indicators creates dashboard overload and prevents teams from acting on the data that matters.

5. What Is a Good Click-Through Rate for Email Marketing in 2026?

The average email click-through rate in 2025 was 2.09% across all industries, according to MailerLite benchmark data covering 3.6 million campaigns. Automated email flows typically achieve higher CTRs (4% to 5%) compared to broadcast campaigns because they are triggered by subscriber behavior and are more relevant.

6. How Do You Calculate Customer Acquisition Cost?

Customer acquisition cost is calculated by dividing total marketing and sales expenses by the number of new customers acquired during the same period. For example, if you spend $10,000 on marketing and sales in a month and acquire 50 new customers, your CAC is $200. A healthy CAC should be recoverable within 3 to 6 months of the customer relationship.

7. Why Is Email Deliverability Rate Important as a Performance Indicator?

Email deliverability rate is the foundation of all email marketing performance indicators. If emails do not reach the recipient inbox, open rates, click rates, and conversion rates all drop to zero. Industry benchmarks target a deliverability rate of 95% or higher. Factors that affect deliverability include sender reputation, domain authentication, list hygiene, and email content quality.

8. What Is Net Promoter Score and How Does It Relate to Marketing?

Net Promoter Score measures customer loyalty by asking how likely a customer is to recommend your brand on a scale of 0 to 10. The score is calculated by subtracting the percentage of detractors (0 to 6) from the percentage of promoters (9 to 10). NPS is a retention-stage KPI that helps marketers evaluate whether their communications build long-term brand advocacy.

9. How Do You Measure ROI on Marketing Communications?

Marketing communications ROI is calculated by subtracting campaign costs from campaign revenue, then dividing by campaign costs, and multiplying by 100. For example, a campaign that costs $5,000 and generates $20,000 in revenue has a 300% ROI. Email marketing delivers an average ROI of $36 to $42 per dollar spent, making it one of the highest-ROI communication channels.

10. What Is the Difference Between Impressions and Reach?

Impressions count the total number of times your content is displayed, including repeat views by the same user. Reach counts only unique users who see your content at least once. A campaign with 10,000 impressions and 5,000 reach means each user saw the content an average of 2 times. Reach measures audience breadth, while impressions measure exposure frequency.

11. How Often Should I Review Marketing Communications KPIs?

Campaign-level KPIs like click-through rate and conversion rate should be reviewed weekly or after each campaign send. Strategic KPIs like customer acquisition cost, CLTV, and ROI should be reviewed monthly or quarterly. Reviewing too frequently leads to overreacting to normal variance. Reviewing too infrequently delays corrective action on underperforming campaigns.

12. What Is ECPM in Email Marketing?

ECPM stands for effective cost per mille (thousand) and measures the revenue generated per 1,000 email subscribers. ECPM reporting helps email marketers understand the monetary value of their subscriber list and compare revenue efficiency across segments, campaigns, and time periods. This metric is particularly useful for publishers, affiliates, and ecommerce marketers.

13. How Do Apple Mail Privacy Protection Settings Affect Email KPIs?

Apple Mail Privacy Protection, launched in September 2021, automatically pre-loads email content and tracking pixels for Apple Mail users. This makes every email appear “opened” regardless of whether the recipient actually viewed it. Since Apple Mail accounts for roughly 46% of email clients, reported open rates are inflated by approximately 18 percentage points industry-wide.

14. What Are Vanity Metrics in Marketing Communications?

Vanity metrics are data points that look impressive but do not connect to business outcomes. Examples include total social media followers, raw page views, and email list size without engagement context. These metrics can create a false sense of success. Effective KPIs like conversion rate, CAC, and revenue per email are actionable because they directly inform budget and strategy decisions.

15. How Do You Set KPI Targets for a New Marketing Campaign?

Setting KPI targets for a new campaign requires establishing a baseline first. Run the campaign for one full cycle (typically 4 to 8 weeks) while tracking all relevant metrics. Compare your baseline data against industry benchmarks. Then set targets that represent a 10% to 20% improvement over your baseline. Avoid setting targets based solely on industry averages because your audience, product, and market position create unique performance dynamics.

16. What Is a Good Customer Lifetime Value to Customer Acquisition Cost Ratio?

A healthy CLTV-to-CAC ratio is 3:1 or higher, meaning each customer generates at least three times more revenue than the cost to acquire that customer. A ratio below 1:1 means you are losing money on every customer acquired. A ratio above 5:1 may indicate underinvestment in marketing, leaving growth opportunities on the table.

17. How Do Automated Email Flows Compare to Broadcast Campaigns in Performance?

Automated email flows consistently outperform broadcast campaigns across all major KPIs. Automated flows achieve open rates above 45% and click rates above 4%, compared to broadcast campaign averages of 43% open rate and 2% click rate. The performance difference comes from behavioral triggers that send the right message at the moment of highest intent.

18. What Is Share of Voice and Why Should Marketers Track It?

Share of voice measures your brand’s visibility relative to competitors within a specific channel or topic. It is calculated by dividing your brand mentions by total market mentions. Research from the Institute of Practitioners in Advertising found that brands with share of voice exceeding their market share tend to grow, making SOV a leading indicator of future market performance.

19. How Do You Improve Email Deliverability Rate?

Improving email deliverability rate requires maintaining clean subscriber lists, authenticating your sending domain with SPF, DKIM, and DMARC records, monitoring sender reputation, keeping bounce rates below 2%, and sending consistent volumes. Sudden spikes in sending volume trigger spam filters. Using a platform with built-in list hygiene and domain authentication tools simplifies this process.

20. Can You Track Marketing Communications KPIs Across Multiple Channels in One Dashboard?

Yes, but it requires either an integrated marketing platform or a business intelligence tool that connects to multiple data sources. For email marketing KPIs specifically, platforms like Emercury consolidate open rate, click rate, conversion rate, deliverability, and revenue per subscriber into a single reporting dashboard. Cross-channel KPI tracking typically requires connecting email, social, paid media, and web analytics data through a centralized analytics platform.
