How to read your Tds.net verification result

Every check returns one of three clear outcomes so you know exactly what to do with the address.

Passed - Safe to Send

The mailbox exists and accepts mail. Send with confidence, the address is deliverable.

Failed - Do Not Send

The mailbox does not exist, is disposable, or will hard-bounce. Remove it to protect your sender reputation.

Unknown - Use Caution

The server is catch-all or greylisting, so existence cannot be confirmed. Send selectively and watch engagement.

Can you verify Tds.net email addresses?

Yes. tds.net is a valid email domain, operated by TDS Telecom. Addresses are persistent and real mail reaches a genuine recipient. Individual mailboxes still go stale, so verify each one before you send.

Verification method

SMTP

A live SMTP handshake connects to Tds.net'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.

Accuracy

99.7%

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.

Why verify Tds.net emails before you send?

Every unverified address is a gamble. Here is what happens when you skip verification and mail a list that has not been cleaned.

Filter abandoned accounts

Free inboxes get abandoned constantly. Verification drops the dead tds.net mailboxes before you mail them.

Catch typos

Mistyped tds.net addresses fail a real SMTP check, so they never turn into a hard bounce.

Protect deliverability

A clean list keeps your bounce rate low, and a low bounce rate is what protects inbox placement on a big send.

Lift open rates

Mailing only live tds.net addresses raises every rate that matters: opens, clicks, and replies.
