Hostinger Email Email Verification
Hostinger provides business and titan-powered email for domains hosted on its widely used web hosting platform.
How Hostinger Email Handles Verification
Hostinger email runs on its own platform and, for many domains, on Titan. Behavior depends on the setup, but unknown recipients are commonly rejected with a 550, making mailbox existence verifiable unless a catch-all is enabled.
What Mailthentic does
We detect the MX target, complete the SMTP handshake, run a catch-all probe, and apply greylisting retries to classify Hostinger-hosted addresses accurately.
