The Power of Re-Engagement Email Subject Lines

Imagine this: you’ve spent hours crafting the perfect re-engagement email, filled with exciting updates, new products, and special deals. But without a great subject line, your email might never be opened. Subject lines, being the initial point of contact, greatly influence whether your message gets read or not.

A well-crafted subject line can significantly impact open rates and drive revenue by re-engaging inactive subscribers. Companies that run email re-engagement campaigns, like Skillshare, Domino’s, and Hulu, understand the importance of creating engaging subject lines that pique the recipient’s interest. These companies manage to re-engage subscribers and pique their interest in their offerings through subject lines that provoke curiosity, provide relevant content, and instill a sense of FOMO.

Best Practices for Crafting Re-Engagement Email Subject Lines

Creating effective re-engagement email subject lines requires a focus on:

  • Clarity

  • Personalization

  • Urgency

  • Simplicity

All while keeping a creative edge. These factors play a vital role in catching your subscribers’ attention and enticing them to open your email. Remember that the perfect subject line length is between 6 to 10 words for maximum impact and to avoid the risk of cropping on mobile devices.

We’ll delve into these best practices further, examining how they can be employed in crafting subject lines that resonate with your inactive subscribers and enhance your re-engagement initiatives.

Clarity and Conciseness

Keep your subject lines short and clear to ensure the main message is conveyed without overwhelming the reader. Ensuring your subscribers grasp your email’s value and relevance from the outset relies heavily on clarity and conciseness.

No one wants to spend time deciphering a convoluted subject line – so focus on getting straight to the point and providing a clear call to action or reason to open your email.


Did you know that including the reader’s name in the subject line can increase the open rate of your emails by 7%? Personalization, which involves recognizing individual preferences or past interactions, can markedly enhance open rates and foster deeper customer engagement. It aids in crafting a subject line that resonates with your audience and spurs them into action.

Personalization goes beyond just adding the recipient’s name; it’s about understanding their needs and preferences and tailoring your messaging to cater to them, creating a truly personalized experience.

Creating Urgency

Urgent subject lines can encourage immediate action and help you boost click-to-open rates. Instilling a sense of urgency in your subject lines with phrases like:

  • “last chance”

  • “limited time offer”

  • “act now”

  • “don’t miss out”

can prompt swift action from your subscribers.

Emails that communicate urgency can drive up to 14% higher click-to-open rates, so don’t miss out on this opportunity to maximize your email marketing re-engagement efforts.

Simplicity and Creativity

The best subject lines strike a balance between simplicity and creativity. While it’s important to keep your subject lines simple and easy to understand, adding a touch of creativity can grab attention and pique curiosity.

Utilizing FOMO (Fear of Missing Out) in your subject lines, for instance, can prove potent given that nearly 70% of millennials and 56% of social media users experience it. By combining simplicity with creativity, you can craft subject lines that stand out in your subscribers’ inboxes and entice them to re-engage with your brand.
