verifier.sendpath.ai
This server checks whether email addresses exist, for customers of SendPath, before they send to them. It asks the recipient's mail server once, the way any sending server does (EHLO, MAIL FROM, RCPT TO), then says goodbye. It never sends a message.
Don't check my domain
If you manage a domain and don't want SendPath to contact its mail servers or look up anyone there, enter it here. It takes effect at once, for the domain and its subdomains.
Please use this only for a domain you manage. If you run a mail service for many domains, or need anything else, write to abuse@verifier.sendpath.ai.
