How it works

How SecureMessage Works

A straightforward setup process that gets you sending secure email in minutes, not days.

Point your MX records or use our SMTP relay. Your existing email addresses and domains stay the same.

TLS 1.3 in transit, DKIM signing, SPF, and DMARC are configured automatically. No manual DNS gymnastics.

Access via IMAP/SMTP, REST API, or our web interface. Works with every mail client, framework, and language.
