List cleaning and permission pass email templates

A permission pass asks subscribers to confirm they still want your mail before you clean the list. A sunset email is the last one before an inactive address is suppressed. Both protect your sender reputation, and both work better when the list was verified first, so the people who never answer are not simply dead addresses.

Verify your list before you send

The best template still bounces off an address that does not exist, and a high bounce rate is the quickest way to get a sending domain throttled. Upload the CSV and every address gets a live mailbox check, with valid, risky and invalid split into separate files.

Clean your next list before it bounces
