Transactional send + inbound hatch

Zipper Mail

Zipper Mail (also called Zipper Email) is transactional email on Zipper’s own MTA. Add a domain, publish SPF (include:_spf.tinyzipper.com), DKIM, and DMARC, verify DNS, then send with POST /api/v1/email/send (all plans) or SMTP at smtp.tinyzipper.com:587 on Starter+. Messages are DKIM-signed on this Global Server node and relayed by Postfix. Attachments, batch, schedule, tags, webhooks, and one-click unsubscribe are built in. Inbound stores encrypted messages and routes to mailbox, webhook, or function. Webmail at mail.tinyzipper.com. Not a marketing blast tool — batches cap at 50 recipients per message.
