GET
https://api.us.nylas.com/v3/activity/send/messages/{message_id}Return a message's delivery status
Returns the delivery timeline of one message for each of its recipients: when Nylas accepted it, and whether it was delivered, bounced, marked as spam, or rejected. Use it to check whether a message reached a recipient and, if it didn't, why. Covers messages sent in the last 90 days.
Path parameters
The ID of the message. For an Agent Account send, this is the message ID the send returned. For a
transactional send, it's the message's Message-ID header, such as
<[email protected]>. Percent-encode it in the path:
%3C0100019a1b2c3d4e%40mail.example.com%3E.
