How do I set a custom expiration date on marketing emails?
Hello @gmh!
Here are steps to set a custom expiration date for a marketing coupon:

3. You can then add a custom expiration date under Expires On. Click Done to save changes.

Keep in mind if you don’t enter a custom expiration date a coupon will expire automatically 2 months after the campaign is sent.
Let me know if you have any questions! Happy to help!
Thank you so much!
