SMTP relay

An SMTP relay that just works

Sendscape is an SMTP relay service for applications. Point any tool that speaks SMTP at smtp.sendscape.ai, port 587 with STARTTLS, and your email is DKIM-signed, delivered and logged - no code changes beyond the credentials.

What is an SMTP relay?

An SMTP relay is a mail server that accepts email from your application and delivers it to the recipient’s inbox on your behalf. Instead of running and warming up your own mail server, you hand messages to a relay that already has authenticated domains, reputation management and bounce handling.
