We've been working for the last couple of months to programmatically expose Proof of Mailing on a per letter basis via our API product. We’re pleased to announce that this feature is now live for all Enterprise edition customers of Lob Print & Mail!
For U.S. letters, we will now provide you with the confirmed date and time of handoff to USPS on a per letter basis. This can act as a proof of mailing for compliance use cases, or simply give your team additional insight into production and delivery timing. You can access this new “Mailed” event on a per letter basis in the letter API response and Dashboard, subscribe to this new event via Webhooks, as well as track this event in aggregate in our Mail Analytics Dashboard.
This new feature comes with Enterprise editions of Lob Print & Mail. If that’s you, you are already able to see Mailed events for U.S. letters on your Dashboard, as well as via the API. Check out our documentation to learn more. If you’re not, check out our pricing by tier and contact our sales team if you’d like to upgrade to gain access to this feature!
As always, please reach out to us with any comments, questions, or feedback you may have. We love hearing from you and are always improving our offerings based on your thoughts!
