Automatically resend an email to contacts who don't open

Article: 000022442
Updated: April 14, 2025

Schedule an email to automatically resend with an updated subject line to contacts who didn't open it

Email Plus IconReview your plan: This feature is not available in all Constant Contact plans. If you don’t have full access, you may need to upgrade your plan.

 

Contacts don't open emails for a variety of reasons: they're too busy, your email got buried on a busy mailing day, or they might not find your subject line that interesting. The good news is that you can set your email to automatically resend to the contacts who didn't open it the first time, and tweak your subject line for them as well.
 

 

  1. When you're finished editing your email draft, click Continue.

    Continue Button
     
  2. Select the lists you want to send your email to. If you filter your lists by tags or send to a segment, those selections stay the same when the email is resent.
    Note: Resending to Non-Openers isn't available while running a subject line A/B test. The Early Results email still sends with the original email, but you won't receive a second one when your email resends.
  1. Check the "Resend to Non-Openers" box.

    Select Recipients Options and Resend to Non-Openers Option
     
  2. Select the date and time you want the email resent. You can choose between 12 hours and 10 days after the original send date.
    Light Bulb IconTip: Of all the contacts who will open your email, 89% open within the second day of receiving it, and 93% open by the third day. Waiting for the fourth day to resend ensures you're less likely to resend an email to someone who was already going to open - which could be seen as spam and result in complaints or unsubscribes!

    Calendar Date and Time Drop-down Menu
  1. Update your subject line to differentiate it from your original email and avoid having your resend marked as spam. Once your email is scheduled, this subject line cannot be edited. The preheader for the resent email will be the same as the preheader on the original email.
  1. Click Confirm.

  2. Use the toggle to choose when you want to send your email:
    • Send Now - To immediately begin sending your email to your contacts.
    • Schedule for Later - To select a future date and time to send your email, up to a year in advance.
  3. Click Send Now or Schedule.

  4. Click Send to confirm your selections.

If you change your mind about resending to non-openers, you can cancel it any time before the resend date you chose. Please note that if you choose to resend to non-openers, you cannot set up a Subject Line A/B Test. Once your email is resent to the contacts who didn't open the original, you can view the results on the Email Details page. The results for your original and resend will be separated.
