Resend Emails to Unopened: Best Practices Guide

Re-engage families who missed your initial email campaign by resending the same content for better results. Studies show parents often overlook emails in their busy schedules, giving you a second chance to connect.

However, balance is key—too many repeat emails can lead to complaints and unsubscribes. Here's how to use this feature effectively.

Main Objectives

  • Increase engagement with your email campaigns
  • Avoid complaints and unsubscribes

Before You Resend: Important Considerations

Timing Matters

Resend your campaign within 12 hours to 10 days of the original send. This window follows industry best practices and balances maximum engagement with minimal negative feedback.

Choose the Right Emails

Only resend high-performing campaigns. If your emails regularly see open rates above 20%, resending to unopened recipients can boost results.

Change Your Subject Line

Update the subject line to catch attention and avoid looking repetitive. A fresh angle helps your email stand out in busy inboxes.

Resend Once Only

Limit yourself to one resend per campaign. Multiple attempts annoy recipients and can damage your sender reputation.

How to Resend Emails to Unopened Recipients

  1. Navigate to Marketing → Email
  2. Find the campaign you want to resend
  3. Click the three dots next to the campaign name
  4. Select "Resend to Unopened"
  5. Enter your new subject line
  6. Set your schedule time (must be 12 hours to 10 days after original send)
  7. Click Confirm

Enrollio creates a new campaign with the same content, scheduled to send only to families who didn't open the first email.
