How do I check a whole list of ABV addresses?
- Export the list as a CSV or copy the email column; ABV 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 an ABV email address?
- Type or paste one address, such as
[email protected]. - Press Check. The tool checks the syntax and domain, asks ABV's server about a random address that can't exist, then about yours, and disconnects before anything is sent.
- Read the verdict: valid means ABV 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 ABV that is usually a cut-short check, not a bad address.
Example
- You enter
- One address:
[email protected]. - You get
- Valid when ABV accepts the mailbox after rejecting a random address; invalid ("Mailbox not found") when it answers
550 5.1.1 … User unknown in virtual mailbox table; 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 an abv.bg address exists without emailing it?
Ask ABV's mail server instead of the mailbox. On 8 November 2026 abv.bg published two MX hosts, pmx.abv.bg and smx.abv.bg. On 13 October 2026 they answered a made-up address at RCPT TO with 550 5.1.1 … Recipient address rejected: User unknown in virtual mailbox table, and a fresh made-up address got the same rejection through this checker on 8 November.
So a single ABV mailbox can be confirmed: a rejection comes back invalid ("Mailbox not found") and an acceptance valid. The ABV provider page has the full DNS snapshot.
Why do abv.bg addresses go dead?
ABV.bg's terms ask users to sign in at least once every 24 months; otherwise Net Info deletes the archive of received mail. After three years without sign-in it sends a notice with a 14-day deadline, and after five years it may delete the whole mailbox and free the username for others to register.
ABV's bulk sender guidance describes a 14-day quarantine for new sending domains, capped at 5,000 emails a day, and says unsigned mail is likely to be rejected or filtered. Re-check Bulgarian lists before a first send, for example with the bulk verifier, and remove the rows that come back invalid.
What can this checker confirm at ABV?
Each row is something the check runs on an ABV 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: ABV 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.
