MailSureMX

Secure & authenticated email delivery infrastructure

MailSureMX.com is an infrastructure domain used to send authenticated, TLS-encrypted email on behalf of verified organizations. This domain is not a marketing site — it exists to provide transparency, abuse contacts and attestations for proper mail delivery.

Authenticated sending

All outbound mail is cryptographically signed (DKIM) and covered by SPF. DMARC monitoring is enabled to protect recipients.

Encrypted in transit

Transport Layer Security (TLS) is used for mail delivery where supported by receiving servers — ensuring mail is encrypted in transit.

We process abuse and security reports promptly. See contact details below for reporting spam, abuse or security issues.
