Telia email checker: does this telia.com mailbox exist?
In short: Asks Telia's own mail server whether a telia.com mailbox exists, without sending anything, after syntax, domain, disposable and role checks. Limit: A valid result shows Telia accepted the mailbox today, not that anyone reads it.
To check if a telia.com address exists, enter it here. The checker asks Telia's mail server about the mailbox at RCPT TO, then disconnects before any message is sent. It rejected a made-up address with 550 RCPT TO:<…> User unknown on 8 November 2026, so a missing mailbox comes back invalid and an accepted one valid.
Price: this tool is free. Checking a whole email list is from $9/mo, and the first 100 checks are free with Google, no card. Check your list free nowSee pricing
Tuned for telia.com. Five checks a minute, no account needed. Nothing is sent to the address — we ask its mail server whether the mailbox exists, then disconnect.

How do I check a whole list of Telia addresses?
- Export the list as a CSV or copy the email column; Telia rows and every other domain can go in together.
- Upload or paste it at /verify. The first 100 email checks are free with a Google sign-in, no card.
- For every list after that, Pro includes unlimited email verification. Fair use: the first 100,000 checks a month at full speed, then slower, never cut off.
How do I check a Telia email address?
- Type or paste one address, such as
[email protected]. - Press Check. The tool checks the syntax and domain, asks Telia's server about a random address that can't exist, then about yours, and disconnects before anything is sent.
- Read the verdict: valid means Telia accepted the mailbox and rejected the made-up one, invalid means it said the user is unknown, risky means the check didn't get a clear answer.
- If it comes back risky, check again later: with Telia that is usually a cut-short check, not a bad address.
Example
- You enter
- One address:
[email protected]. - You get
- Valid when Telia accepts the mailbox after rejecting a random address; invalid ("Mailbox not found") when it answers
550 RCPT TO:<…> User unknown; risky only when the check gets no clear answer. - Limits
- Five checks a minute per IP address, one address at a time, no account needed.
How do I check if a telia.com address exists without emailing it?
Ask Telia's mail server instead of the mailbox. On 8 November 2026 telia.com published one MX host, mail.telia.com. That day a made-up telia.com address got 550 RCPT TO:<…> User unknown at RCPT TO through this checker.
So a single Telia mailbox can be confirmed: a rejection comes back invalid ("Mailbox not found") and an acceptance valid. This is one check on one day; we have no earlier observation for this domain.
Why do Telia addresses go dead?
Telia Sweden's Telia Webmail FAQ says its mail service is only meant for customers with at least one base service (mobile, broadband or TV), costs 9 kronor a month from 1 October 2025 for up to 5 addresses, and that accounts not meeting this would be closed on 1 December 2025. Telia's guide to clearing mail shows the webmail at webmail.telia.com.
So telia.com contacts from people who left Telia, or didn't take up the paid service, may have been closed since December 2025. Re-check Swedish lists before a campaign, for example with the bulk verifier; the Telenor email checker covers Norway's online.no.
What can this checker confirm at Telia?
Each row is something the check runs on a Telia address, and the result you can get from it.
| Check | Can we confirm it? | Result when it fails |
|---|---|---|
| Syntax (the address is written correctly) | Yes | Invalid |
| Domain and mail server (MX) | Yes | Invalid, with a typo suggestion where one fits |
| Disposable or role address | Yes | Invalid (disposable) or risky (role) |
| The mailbox exists | Yes: Telia answers at RCPT TO (550 User unknown) | Invalid, "Mailbox not found" |
| A temporary reply or timeout | No answer to read | Risky, worth checking again later |
| Someone reads the inbox | No checker can | Use opens, replies or a small first send |
Our checking server offered a made-up address and disconnected without sending, through this checker on 8 November 2026; earlier checks are dated in the text.

That was one address. Most people have a list.
The free checker does five addresses a minute, one at a time — fine for spot-checking, useless for a CSV of 40,000.
- Upload a CSV up to 100,000 rows
- Valid, risky and invalid exported as separate files
- Repeat checks free for 14 days, no new connections
Plans from $9 a month, cancel anytime, no contract. Sign in with Google and your first 100 email checks are free, no card. The free tools stay free either way.
