Informed Delivery is a service provided by the USPS which allows users to preview what mail is arriving in their mailboxes. Users get an email when they have mail on the way, along with a photo of the mail that’s coming. They can even reschedule their mail, add delivery instructions, or redirect it to a post office. We’ve integrated with this amazing service by synchronizing with your mailing list, letting you see who checks their mail digitally. Your users can see a preview of your direct mailer, and you can get notified when they do! Our Mail Tracking page has more information on how you can keep track of your mailers.
