How to check if a mail.ru email address exists
How do I check if a @mail.ru address exists? Paste the address into a checker for the syntax, mail server, disposable and role checks, but a mailbox check cannot confirm it: Mail.ru's server accepted a made-up @mail.ru address on 23 October 2026, so real and fake addresses get the same yes. SimpleVerifier returns @mail.ru addresses as risky ("Accepts all addresses"), never valid; only a clean delivery, open or reply proves one is live.
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.

Can you verify @mail.ru addresses?
PartlyPartly. @mail.ru accepts any recipient, so a single mailbox can't be confirmed.
The checker probes @mail.ru, but it first offers a random address that can't exist. mail.ru'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 addressesWhat we can and cannot confirm at @mail.ru
We can confirm
- The address is written correctly (syntax), and the domain publishes working mail servers (MX).
- Whether it is a disposable or role address (info@, sales@) or a likely typo of a bigger domain.
We cannot confirm
- Whether a single @mail.ru mailbox exists. Mail.ru says yes to every address, so the result is risky ("Accepts all addresses"), never valid.
- Which risky addresses will bounce. Send a small first batch and suppress the hard bounces.
- Whether a person reads the inbox, wants your email or agreed to receive it. No checker can see that.
Anything we cannot confirm comes back risky, never valid.
What we measured at mail.ru
Measured by SimpleVerifier on 23 October 2026 through our production checker and public DNS. No message was sent and no real person's address was used.

Where your @mail.ru addresses live
Already paying another verifier?
Mail.ru addresses can't be confirmed with a mailbox check. On 12 October 2026 the mail.ru mail server mxs.mail.ru accepted a made-up recipient at RCPT TO with 250 Go ahead, so real and fake addresses get the same answer. Expect mail.ru 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 Mail.ru's server says about a missing mailbox
Mail.ru answered our made-up mail.ru address with 250 Go ahead 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 mail.ru 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.
Mail.ru addresses go quiet after six months
VK's user agreement lets it block or delete a mailbox after six straight months with no logins, so a Mail.ru address that was fine a year ago can be dead today. Because Mail.ru's server accepts any recipient during a check, recency of engagement is the signal to lean on for this segment.
The same agreement says a closed mailbox name can't be registered again, so a dead Mail.ru address won't pass to a stranger. Anonymous aliases, up to 10 per mailbox, can look like separate people while all reaching one inbox.
Cleaning mail.ru addresses when the server says yes to everything
Don't delete mail.ru 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 mail.ru 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
- How do I check if a @mail.ru address exists?
- Paste the address into a checker for the syntax, mail server, disposable and role checks, but a mailbox check cannot confirm it: Mail.ru's server accepted a made-up @mail.ru address on 23 October 2026, so real and fake addresses get the same yes. SimpleVerifier returns @mail.ru addresses as risky ("Accepts all addresses"), never valid; only a clean delivery, open or reply proves one is live.
- Can you verify @mail.ru addresses?
- Partly. @mail.ru accepts any recipient, so a single mailbox can't be confirmed. The checker probes @mail.ru, but it first offers a random address that can't exist. mail.ru'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 mail.ru address exists without emailing it?
- Not reliably. On 12 October 2026 Mail.ru's server accepted a made-up mail.ru address at the RCPT TO step, so a mailbox check gets the same yes for real and fake addresses. Verifiers return mail.ru addresses as risky (accept-all).
- What mail servers does mail.ru use?
- On 12 October 2026, mail.ru published these MX hosts: mxs.mail.ru. You can look them up yourself with the free MX lookup tool.
- Should I delete mail.ru addresses that come back risky?
- No. For mail.ru, 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.
