Mail servers for 3email.com
3email.com publishes 2 MX records. Senders deliver to the lowest-priority host first, mail.protonmail.ch, and fall back down the list if it does not answer.
Who runs the mail
The hosts match the pattern of Proton Mail. Proton Mail hosts the mailboxes. Unknown addresses are rejected at the handshake, and the service is a privacy-focused provider used for real accounts, not a burner service.
What this means for verification
An address at 3email.com passes the free checks (syntax, MX, lists), so the API goes on to the mailbox-level SMTP handshake, which ends before any message is sent. The result is deliverable, risky, or undeliverable with a reason field that names the evidence.
