Built for product email

Make email a reliable part of your product

Connect email to product events, separate different message types and give your team the data needed to investigate every send.

Trigger email from any product event

Send onboarding messages, usage alerts, reports, invitations and account updates through the Mission Inbox REST API or SMTP.

Keep each email stream isolated

Separate transactional messages, product notifications and lifecycle email so a problem with one stream does not affect every message your product sends.

Trace every email from send to delivery
