Yes. You can verify any @Usa.com address in real time with a direct SMTP handshake that provides 99.7% accuracy. Usa.com is operated by USA.com Inc., runs 2 mail servers, enforces 2 of 3 authentication standards, and is currently responding to SMTP.
Every check returns one of three clear outcomes so you know exactly what to do with the address.
The mailbox exists and accepts mail. Send with confidence, the address is deliverable.
The mailbox does not exist, is disposable, or will hard-bounce. Remove it to protect your sender reputation.
The server is catch-all or greylisting, so existence cannot be confirmed. Send selectively and watch engagement.
usa.com publishes 2 MX records. The primary mail exchanger is mx00.mail.com, hosted by mail.com, and it is currently reachable and answering SMTP. Mail is routed through these servers in priority order, lowest number first.
| Priority | Hostname | IP | Status |
|---|---|---|---|
| 10 | mx00.mail.com | 74.208.5.20 | Reachable |
| 10 | mx01.mail.com | 74.208.5.22 | Reachable |
220 mail.com (mxgmxus001) Nemesis ESMTP Service readyYes. usa.com is a valid email provider, operated by USA.com Inc.. Addresses are persistent and real mail reaches a genuine recipient. Individual mailboxes still go stale, so verify each one before you send.
A live SMTP handshake connects to Usa.com's mail server and asks whether the mailbox exists using the RCPT TO command, without ever transmitting a message. The recipient never sees the check.
Each address runs through 30+ checks including SMTP existence, catch-all detection, role-account filtering, and disposable matching. The same engine has verified billions of addresses since 2012.
