MailRoute review

MailRoute is a straightforward filtering service that sits in front of your mail server and publishes its price list in full. Basics costs $2 per user per month and includes inbound and outbound security, content filtering, DKIM signing, quarantine notifications, real-time mail logs and integration with Microsoft 365 and Google Workspace. Impersonation protection is available on all plans in early access. Enterprise, at $3, adds phone support, SSO, LDAP and Active Directory sync, an API, white-glove onboarding and an always-on 30-day email continuity store users can reach during outages. Enterprise U.S., at $4, keeps data in US datacenters with US-citizen-only access, and supports ITAR, HIPAA with a BAA and NIST 800-171. Every tier queues mail for up to 15 days if your server stops responding. Aliases and distribution lists cost nothing, and there are no seat minimums or contracts. What it lacks is behavioral detection of BEC and post-delivery removal, so treat it as a dependable filter and outage buffer rather than a full anti-BEC platform.

Who it is for
