Return to Sender: What it means and what to do

If a document can't be delivered digitally - usually because a subscription is invalid or cannot be matched - the mail item will be marked as "Undeliverable" and moved to the Undeliverable tab on the Mail page.

From here, you can:

• View any undelivered documents

• Download and reprint individual items

• Mark items as “Undeliverable Actioned” after you've reprocessed them

• Investigate delivery issues (e.g. subscription mismatch, missing Contact) and review affected Contacts.
