Prodigy email checker: does this prodigy.net.mx mailbox exist?
In short: Asks the mail server behind Telmex's prodigy.net.mx whether a mailbox exists, without sending anything, after syntax, domain, disposable and role checks. Limit: A valid result shows the server accepted the mailbox today, not that anyone reads it.
To check if a prodigy.net.mx address exists, enter it here. The checker asks the mail server that receives Telmex's prodigy.net.mx mail about the mailbox at RCPT TO, then disconnects before any message is sent. It rejected a made-up address with 550 5.1.1 … recipient rejected on 8 November 2026, so a missing mailbox comes back invalid and an accepted one valid.

How do I check a whole list of Prodigy addresses?
- Export the list as a CSV or copy the email column; Prodigy 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 Prodigy email address?
- Type or paste one address, such as
[email protected]. - Press Check. The tool checks the syntax and domain, asks the server about a random address that can't exist, then about yours, and disconnects before anything is sent.
- Read the verdict: valid means the server accepted the mailbox and rejected the made-up one, invalid means it rejected the recipient, risky means the check didn't get a clear answer.
- If it comes back risky, check again later: with prodigy.net.mx that is usually a cut-short check, not a bad address.
Example
- You enter
- One address:
[email protected]. - You get
- Valid when the server receiving prodigy.net.mx mail accepts the mailbox after rejecting a random address; invalid ("Mailbox not found") when it answers
550 5.1.1 … recipient rejected; 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 prodigy.net.mx address exists without emailing it?
Ask the mail server instead of the mailbox. On 8 November 2026 prodigy.net.mx published three MX hosts, publicms1.mail2world.com, publicms2.mail2world.com and publicms3.mail2world.com. That day a made-up prodigy.net.mx address got 550 5.1.1 … recipient rejected at RCPT TO through this checker.
So a single Prodigy 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. Note that prodigy.net.mx (Telmex, Mexico) is not the AT&T domain prodigy.net; for that one use the AT&T email checker.
Why do prodigy.net.mx addresses go dead?
Telmex's Prodigy mail FAQ says Telmex deletes accounts for inactivity, for messages stored more than a year, for moves or administrative reasons, and when the service is cancelled. The same FAQ says an account can be suspended for non-payment or when malware is detected.
prodigy.net.mx is one of the domains of Telmex's Infinitum Mail, alongside infinitummail.com, telmexmail.com and others, per Telmex's mail settings sheet. Re-check Mexican lists before a campaign, for example with the bulk verifier, and remove the rows that come back invalid.
What can this checker confirm at Prodigy?
Each row is something the check runs on a Prodigy 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: Prodigy answers at RCPT TO (550 5.1.1 recipient rejected) | 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.

Common questions
- How do I check if a prodigy.net.mx email address is valid?
- Enter it here. The checker confirms the syntax and mail server, then asks the server about the mailbox without sending. It rejected a made-up prodigy.net.mx address on 8 November 2026, so a missing mailbox comes back invalid.
- Does Telmex delete inactive Prodigy accounts?
- Telmex's Prodigy FAQ lists inactivity of the account as one reason it deletes accounts, along with cancellation of the service and administrative reasons.
- Is prodigy.net.mx the same as prodigy.net?
- No. prodigy.net.mx is Telmex's Mexican domain, part of Infinitum Mail; prodigy.net is an AT&T domain with its own checker.
- What does 550 5.1.1 recipient rejected mean from prodigy.net.mx?
- The server said that mailbox doesn't exist. Treat it as a hard bounce and remove the address.
- Is this checker free?
- Yes, five checks a minute with no account. For a whole list, sign in with Google for 100 free email checks, no card, or use a monthly plan.
