WP Poczta email checker: does this wp.pl mailbox exist?

In short: Asks WP Poczta's own mail server whether a wp.pl mailbox exists, without sending anything, after syntax, domain, disposable and role checks. Limit: A valid result shows WP accepted the mailbox today, not that the same person still owns it.

To check if a wp.pl address exists, enter it here. The checker asks WP Poczta's mail server about the mailbox at RCPT TO and disconnects before sending. WP rejected made-up addresses with 550 Podane konto nie istnieje / No mailbox here by that name on 12 October and 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 wp.pl. Five checks a minute, no account needed. Nothing is sent to the address — we ask its mail server whether the mailbox exists, then disconnect.

What can a check confirm at WP Poczta, and what did we measure there? Can you verify a WP Poczta address?

How do I check a whole list of wp.pl addresses?

  1. Export the list as a CSV or copy the email column; wp.pl rows and every other domain can go in together.
  2. Upload or paste it at /verify. The first 100 email checks are free with a Google sign-in, no card.
  3. 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 wp.pl email address?

  1. Type or paste one address, such as [email protected].
  2. Press Check. The tool checks the syntax and domain, asks WP's server about a random address that can't exist, then about yours, and disconnects before anything is sent.
  3. Read the verdict: valid means WP accepted the mailbox and rejected the made-up one, invalid means it said the account doesn't exist, risky means the check didn't get a clear answer.
  4. If it comes back risky, check again later before you drop the address.

Example

You enter
One address: [email protected].
You get
Valid when WP accepts the mailbox after rejecting a random address; invalid ("Mailbox not found") when it answers 550 Podane konto nie istnieje; 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.

Can you check if a wp.pl email address exists?

Yes. On 8 November 2026 wp.pl published mx.wp.pl, then mx5.wp.pl, as its mail servers. On 12 October 2026 WP answered a made-up address at RCPT TO with 550 Podane konto nie istnieje / No mailbox here by that name (#5.1.1), in Polish and English, and a fresh made-up address was rejected again through this checker on 8 November.

A missing wp.pl mailbox therefore comes back invalid ("Mailbox not found"), and one WP accepts after rejecting a random address comes back valid. The WP Poczta provider page has the live DNS. The other big Polish webmails run their own servers and answered checks too: see o2.pl and onet.pl.

Can a wp.pl address belong to someone new?

Yes. WP Poczta's terms allow an account and its contents to be deleted after 180 days without a login, and then let another user take over the old address. A wp.pl contact who has been silent for half a year may now reach a different person, so re-confirm older contacts rather than relying on an old opt-in.

WP's anti-spam policy rejects mail without correct reverse DNS or with SPF or DKIM not aligned to the From address, and its bulk sender recommendations tell senders to remove people who don't open.

Can I check a whole list of Polish addresses?

Yes. Sign in and use the bulk verifier for a CSV or a pasted list; wp.pl rows get the same mailbox check as here, alongside o2.pl, onet.pl, Gmail and everything else.

For one Gmail address, the Gmail address checker works the same way, and the email checker handles any other domain.

What can this checker confirm at WP Poczta?

Each row is something the check runs on a WP Poczta address, and the result you can get from it.

CheckCan we confirm it?Result when it fails
Syntax (the address is written correctly)YesInvalid
Domain and mail server (MX)YesInvalid, with a typo suggestion where one fits
Disposable or role addressYesInvalid (disposable) or risky (role)

A temporary reply or timeoutNo answer to readRisky, worth checking again later

Our checking server offered a made-up address and disconnected without sending, on 12 or 13 October 2026 and again through this checker on 8 November 2026.

Who uses this tool, and for what?

Polish shops and newsletters
Remove deleted wp.pl accounts before WP reads the bounces as a stale list.
Support teams

Lead buyers
Confirm a handful of Polish webmail contacts before importing a list.

What can’t this tool tell you?

  • A valid result shows WP accepted the mailbox today, not that the same person still owns it.
  • A temporary reply or a refused connection comes back risky, not invalid.
  • WP doesn't publish how its servers answer mailbox checks; the handling here is from our own checks, which can change.
  • One address at a time, five a minute.

Common questions

How do I check if a wp.pl email address is valid?
Enter it here. The checker confirms the syntax and mail servers, then asks WP's server about the mailbox without sending. WP rejects addresses that don't exist, so a missing mailbox comes back invalid.
What does Podane konto nie istnieje mean?
It is Polish for "the given account does not exist". WP's server sends it with a 550 code and the enhanced code 5.1.1, so treat it as a hard bounce and remove the address.
Does WP delete inactive accounts?
WP Poczta's terms allow an account to be deleted after 180 days without a login, and the address can then be taken over by another user.
Does this checker work for o2.pl and onet.pl?
This page is tuned for wp.pl. Any other address, including o2.pl and onet.pl, gets the same live check in the general email checker; both answered made-up addresses with a clear rejection in our October 2026 checks.
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.
