How to check if a ukr.net email address exists
Can you verify @ukr.net addresses?
PartlyPartly. @ukr.net accepts any recipient, so a single mailbox can't be confirmed.
Check one address
Five checks a minute, no account needed. Nothing is sent to the address — we ask its mail server whether the mailbox exists, then disconnect.

The checker probes @ukr.net, but it first offers a random address that can't exist. ukr.net's server accepts it, so the checker returns the real address as risky with "Accepts all addresses" rather than calling it valid. It always checks the syntax, the domain's MX records, disposable domains and role addresses such as info@ first.
Accepts all addressesUKR.NET addresses can't be confirmed with a mailbox check. On 13 October 2026 the ukr.net mail server mxs.ukr.net accepted a made-up recipient at RCPT TO with 250 2.1.5 Recipient accepted, so real and fake addresses get the same answer. Expect ukr.net results to come back risky (accept-all), not valid or invalid.
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. See pricing

What UKR.NET's server says about a missing mailbox
UKR.NET answered our made-up ukr.net address with 250 2.1.5 Recipient accepted at RCPT TO, the step where a verifier names the recipient. When a server says yes to an address that cannot exist, its yes for your real address carries no information. SimpleVerifier tests a random address first for exactly this reason and returns ukr.net results as risky with the reason "Accepts all addresses".
Accepting at RCPT TO doesn't mean every message is delivered. Providers that do this usually decide later, after the message is sent, and a missing mailbox then produces a bounce rather than an up-front rejection. That is why accept-all results belong in their own segment: accept-all vs unknown results covers how to treat them.
UKR.NET never reissues a deleted mailbox name
UKR.NET's help says deleted mailbox names can't be registered again by anyone. Incoming mail to a deleted mailbox is rejected, and the owner can restore it within 180 days. A @ukr.net address is never handed to a new person, but it can bounce for good.
The service is run by ТОВ «УКРНЕТ» under its privacy agreement. Because the domain accepts mail for any address at delivery time, a bounce may come back later. Treat later bounces as permanent and remove those addresses.
Cleaning ukr.net addresses when the server says yes to everything
Don't delete ukr.net addresses just because they came back risky; most will be real. Remove what can be proven bad without the mailbox check: syntax errors, typo domains, duplicates and disposable addresses, which the free list health check finds in the browser.
Then send to the ukr.net segment in a small first batch and watch the bounces. Addresses that bounce as unknown users are gone and should be suppressed; the rest have proved themselves. Engagement history is the other strong signal: an address that opened or replied recently is live whatever the check says. Should you send to catch-all emails? walks through the same approach.
Common questions
- Can you verify @ukr.net addresses?
- Partly. @ukr.net accepts any recipient, so a single mailbox can't be confirmed. The checker probes @ukr.net, but it first offers a random address that can't exist. ukr.net's server accepts it, so the checker returns the real address as risky with "Accepts all addresses" rather than calling it valid. It always checks the syntax, the domain's MX records, disposable domains and role addresses such as info@ first.
- Can I check if a ukr.net address exists without emailing it?
- Not reliably. On 13 October 2026 UKR.NET's server accepted a made-up ukr.net address at the RCPT TO step, so a mailbox check gets the same yes for real and fake addresses. Verifiers return ukr.net addresses as risky (accept-all).
- What mail servers does ukr.net use?
- On 13 October 2026, ukr.net published these MX hosts: mxs.ukr.net. You can look them up yourself with the free MX lookup tool.
- Should I delete ukr.net addresses that come back risky?
- No. For ukr.net, risky reflects how the server treats checks, not the address. Remove the ones that fail format, typo-domain and duplicate checks, then send to the rest in a small batch and suppress whatever hard-bounces.
