According to Live Direct Marketing's daily Tranco top-1M scan (July 12, 2026), MailRoute is the mailbox provider for 60 domains — 0.01% of 658,108 domains with MX records. Detection method: primary MX record (lowest preference).
MailRoute is a mailbox provider that functions as a primary MX receiver for a subset of the top-1 million internet domains. It is commonly deployed by smaller and medium-sized organisations, concentrated in the .com namespace, with geographic skew toward the United States and other global markets.
For senders, MailRoute's long-tail distribution means its influence on deliverability is spread rather than concentrated; however, its frequent co-deployment with Amazon SES indicates it serves organisations using hybrid email stacks, making it a practical inclusion in representative testing and reputation monitoring portfolios.

MailRoute frequently appears in hybrid mail architectures where organisations use it for inbound reception whilst routing outbound traffic through Amazon SES or similar services. This separation means authentication (SPF, DKIM, DMARC) must satisfy the receiver's own standards independently of any upstream relay provider. Senders reaching MailRoute recipients should verify authentication records and reputation against the receiver's configuration rather than assuming consistency with the organisation's outbound relay service.
