This article explains how invitation expiration works and how to reactivate expired invitations.
Configure Invitation Expiration
Whether and when invitations expire is defined in the settings of the invitation email.
Before taking any further action, make sure to review and adjust these settings according to your needs, the changes do not have an effect on emails sent in the past. So if you have an invitation with an expired status, changing the settings won't reactivate it.
You can define either a number of days after receiving the invitation email or a fixed date on which all invitations will expire.
If you do not want invitations to expire automatically, we recommend using the last registration date as the RSVP deadline.

What Happens When an Invitation Expires
Once an invitation has the status “expired”, the invited person can no longer register for the event.
How to Reactivate Expired Invitations
To move guests from “expired” back to “pending”, you need to resend the invitation email:
- Go to the invitation list
- Filter by the status “expired”
- Select all guests
- Resend the invitation email
After resending, the guests will be able to register again.
Optional: Adjust the Invitation Email Content
When resending invitations, you can temporarily modify the content of the invitation email if needed.
Afterward, you can revert the message back to its original version.
