Overview

Marketing and product email in one place

Most SaaS teams juggle a marketing tool and a separate transactional provider. GO MAILBOX does both: run your newsletter and lifecycle campaigns, and fire receipts, OTPs and alerts through a REST API on the same verified domain.

  • Send onboarding sequences that activate new signups
  • Announce releases and changelogs to your user base
  • Fire transactional email programmatically via API
  • Keep marketing and product email on one authenticated domain
