The Importance of Reminder Email Subject Lines

Do you ever find yourself overwhelmed with the emails that you get and saying “I’ll get back to that email later”, and never do? Guess what, that’s normal for everyone, including your own subscribers.

And it doesn’t really have to be about coming back to an email, it can be an offer you have made, a deadline you have set, or something you’ve asked of your subscribers. Plenty of times, they fail to take action not because they don’t want to (they do), but they just get overwhelmed and forget about it.

This is where reminder emails come into play, and if you want people to actually open these emails, you’ll want to take a look at this battle-tested list of reminder email subject lines.

If I were you, I would bookmark this article straight away and find a way to use all of these reminder subject lines. It might just be one of the most effective ways to boost your email marketing efforts that you have ever come across.

And this is for several reasons beyond the obvious. Reminder emails boost email engagement which in turn improves deliverability, increases the sense of a “relationship” with your brand, and habituates people to opening your emails.

How Subject Lines Can Impact Open Rates and Engagement in Email Marketing

You know how they say “don’t judge a book by its cover”, yet everyone does, including you and me? Well, subject lines are like that book cover for your emails. In fact, it might be the single most important reason why someone opens your email, or fails to do so.

Think about it from your own perspective. When you encounter an overfilled inbox and are short on time (as most of us are today), what do you do? That’s right, you scan the subject lines. And if a subject line stands out (or the topic is especially relevant at the given moment), you might open it. Otherwise, you ignore and don’t even open most emails.

The reason this matters is that the email open is literally the gatekeeper that stands in front of all of your other efforts in email marketing. Everything else that you do in email marketing is literally dependent on the subscriber opening that email.

But it’s not just about the obvious issues (you can’t sell to someone who didn’t open the email), it goes beyond that. When you get people in the habit of opening your emails, you literally train them to recognize your brand in the inbox, which in turn increases engagement across the board. Think of it as a positive feedback loop.

In a word, you want to find more ways to get people to open more of your emails, and subject lines are a huge part of that. With that said, reminder emails are an especially effective way to practice your subject-line mojo.

Key Elements of an Effective Reminder Email Subject Line

Crafting an effective reminder email subject line is both an art and a science. It requires a delicate balance between capturing attention, conveying value, and maintaining a tone that resonates with your audience.

Here are some key elements to consider:

Clarity: Your subject line should clearly communicate the purpose of the email, whether it’s a reminder, an update, or a call to action.

Urgency: Strategically incorporating a sense of urgency can prompt recipients to open and act on your email more promptly.

👤 Personalization: Tailoring your subject line to the individual recipient can significantly increase open rates and engagement.

✂️ Conciseness: Aim for brevity while still conveying the essence of your message, as lengthy subject lines may be truncated or ignored.

🎯 Relevance: Ensure your subject line aligns with the content of your email and is relevant to your target audience’s interests or needs.

    Tips for Writing Compelling Reminder Email Subject Lines

    While the examples above provide a solid starting point, crafting truly compelling reminder email subject lines requires a strategic approach. Here are some tips to keep in mind:

    👤✨ Leverage Personalization: Incorporating the recipient’s name, location, or other relevant details can significantly increase open rates and engagement.

    ⏰🔥 Create a Sense of Urgency: Use words like “urgent,” “last chance,” or “time-sensitive” to convey immediacy and prompt action.

    💎📈 Highlight the Value Proposition: Clearly communicate the benefit or value the recipient will gain by opening and engaging with your email.

    🎨🔍 Use Emojis Strategically: Incorporating relevant emojis can help your subject line stand out in cluttered inboxes, but use them judiciously.

    🧪🔧 Test and Refine: Continuously A/B test your subject lines to identify what resonates best with your audience and refine your approach accordingly.

    A/B Testing Your Reminder Email Subject Lines

    Do you want to know a magic trick that helps you pinpoint exactly what works? It’s called A/B testing. It’s this really killer feature where we automatically put your subject lines in competition one against the other and tell you who came out the winner.

    If you’re an Emercury user, you will find it a breeze to use this feature. Just make sure to systematically test all of your subject lines against each other, until you find what works best for your different audiences and use cases.

    Oh, and an important side note: when conducting A/B tests, it’s crucial to isolate the variable you’re testing (in this case, the subject line) and keep all other elements consistent. This means keep everything else identical, such as the email content, and recipient list. This ensures that any differences in performance can be attributed solely to the subject line variations.

    Best Practices for Optimizing Open Rates and Engagement

    Are subject lines an amazing way to boost your open rates? They sure are. Should you just obsess with your subject lines and forget everything else? Not really a good idea actually.
    You have to remember that while compelling subject lines are a critical component of successful reminder email campaigns, it’s essential to adopt a holistic approach to optimize open rates and engagement. Here are some best practices to consider:

    • Segment Your Audience:Tailor your messaging and subject lines to specific segments of your audience based on their interests, behaviors, or preferences for more relevance and impact.
    • Optimize Send Times:Analyze your audience’s engagement patterns and send your reminder emails during peak activity windows for maximum visibility.
    • Leverage Preheader Text:The preheader text, which appears alongside the subject line in many email clients, can provide additional context and entice recipients to open your email.
    • Ensure Mobile-Friendliness:With a significant portion of emails being read on mobile devices, ensure your reminder emails are optimized for small screens and easy navigation.
    • Incorporate Multimedia Elements:Strategically incorporating visuals, such as images, GIFs, or videos, can enhance engagement and make your reminder emails more compelling.
