How to Check a List of wp.pl Email Addresses at Once (Polish Lists)
To check many wp.pl addresses at once, use the bulk wp.pl email checker: it cleans the whole list in your browser and asks WP's server about the first 10. Only wp.pl rows count as WP; o2.pl and onet.pl are checked as normal addresses.
A valid result shows the mailbox exists today, not that it is still the same person.
What WP's server says
On 12 October 2026 WP answered a made-up address with 550 Podane konto nie istnieje / No mailbox here by that name (#5.1.1), in Polish and English, and rejected a fresh one again on 8 November. Treat that as a hard bounce.
Why an address may belong to someone new
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. WP's bulk sender recommendations tell senders to remove people who don't open.
The by-hand way
- Filter the sheet to wp.pl.
- Remove repeats and typos.
- Test addresses one at a time with the wp.pl email checker.
In the tool
Paste the list, read flags for typo domains, duplicates, +tag repeats and dead domains, download the clean list, and let the first 10 reach WP for a live answer.
What this check cannot do
- WP doesn't publish how its servers answer mailbox checks; the handling is from our own checks, which can change.
- A +tag repeat is marked as possibly the same inbox, not merged.
- It can't tell whether a reused address belongs to a new person.
Next: the whole list
Use the verify page for the rest: the first 100 checks are free with a Google sign-in, no card.

Common questions
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.
Are o2.pl and onet.pl wp.pl rows?
No. Only wp.pl counts as a WP row; o2.pl and onet.pl are checked as normal addresses.
Can you check wp.pl addresses in bulk?
Yes. WP rejected a made-up address on 12 October 2026 and again on 8 November, so a wp.pl row's result comes from WP's server. About 10 are asked live.
Is it free?
The whole-list pass is free; a Google sign-in gives free checks for the rest.
