About Postmark
Where your application's mail goes out.
Postmark is a transactional email service built around a clear split: every send belongs to a Message Stream, and transactional streams (password resets, receipts, shipping notices, failed-payment alerts) run on a different sending pool than broadcast streams (newsletters, product announcements). The product surface is an Email API, an SMTP relay, templates, inbound parsing, and webhooks for delivery, bounce, open, click and spam-complaint events. The audience is engineering teams that want one job done well: the message that has to arrive within seconds of the event that fired it, in the inbox, with a clean trail of what happened.
The data the connector lifts into a warehouse is the picture finance, support and operations need but rarely see. Sends per stream, per server and per template. Bounces and spam complaints with the address and the reason. Opens and clicks tied back to the customer record. Time from send to delivery per mailbox provider. Joined to the order that triggered the receipt, the invoice that triggered the dunning mail or the support ticket that triggered the resolution notice, the same message log becomes a deliverability dashboard, a billing-cycle audit and a customer-history lookup at the same time.
