When you need to modify the content of emails that are already queued in the backlog for sending to customers, you may want to ensure that the updated copy is used instead of the old version.

Answer

You can update the copy for queued emails in your sequence by following these three simple steps:

Important: When you publish changes to a sequence, the system will automatically upgrade compatible enrollments—including those already mid-sequence—to use the updated copy for all future, unsent steps. Steps that have already been sent will not change.

"Compatible enrollments" are enrollments that can be safely upgraded without breaking their progress. Copy changes and timing adjustments are compatible and will apply to remaining steps for people already in progress. The system will prevent incompatible changes (like deleting steps someone already passed or inserting new steps between completed steps) and prompt you to resolve them before publishing.

Warning: If you upgrade a sequence version while emails are queued but have not yet sent, those queued emails will be reset back to your To-Do list. The system treats queued-but-not-sent emails as incomplete to ensure any changes in placeholders or email content can be reviewed before sending. To avoid this, either wait until queued emails have actually sent before upgrading, or be prepared to re‑queue the emails after upgrading.

1. Navigate to the sequence and update the email copy with your desired changes

2. When publishing your changes, leave "Only update future enrollments" unchecked to apply updates to both current and future enrollments. To see which version each enrollment is currently using, go to the Enrollments tab and filter by 'Sequence Version'.

3. Publish your sequence. All compatible enrollments will automatically upgrade to the latest version and receive your updated copy for their remaining steps.
