Mail.ee email checker: does this mail.ee mailbox exist?
In short: Asks the mail server behind Mail.ee whether a mail.ee 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 mail.ee address exists, enter it here. The checker asks the server that receives mail.ee 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 address rejected: User unknown on 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

How do I check a whole list of Mail.ee addresses?
- Export the list as a CSV or copy the email column; Mail.ee 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 Mail.ee 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 said the user is unknown, risky means the check didn't get a clear answer.
- If it comes back risky, check again later: with Mail.ee 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 mail.ee mail accepts the mailbox after rejecting a random address; invalid ("Mailbox not found") when it answers
550 5.1.1 … User unknown; 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 mail.ee address exists without emailing it?
Ask the mail server instead of the mailbox. On 8 November 2026 mail.ee published one MX host, mx-in.inbox.eu. That day a made-up mail.ee address got 550 5.1.1 … Recipient address rejected: User unknown at RCPT TO through this checker.
So a single Mail.ee 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.
Why do mail.ee addresses go dead?
Mail.ee is run by SIA INBOKSS of Riga, Latvia, according to its terms of service, the same company behind inbox.lv. Its help page on deleting accounts says a mailbox that hasn't been used for a long time is deleted automatically: its status changes to Inactive, then the mailbox is closed, then permanently deleted.
The same page says a closed account is not available for registration again for 2 years or more. So an old mail.ee contact may be closed, and the address won't come back to a stranger quickly. Re-check Estonian lists before a campaign, for example with the bulk verifier; the Inbox.lv email checker covers inbox.lv addresses.
What can this checker confirm at Mail.ee?
Each row is something the check runs on a Mail.ee 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: Mail.ee answers at RCPT TO (550 5.1.1 User unknown) | 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.
