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.

By continuing you agree to our Terms and Privacy Policy.
The checker opens an SMTP conversation with abv.bg's mail server, offers a random address first to rule out a catch-all, then names your address at RCPT TO and disconnects without sending. A rejection comes back invalid ("Mailbox not found") and an acceptance valid ("Mailbox exists"). Temporary replies come back risky. It always checks the syntax, the domain's MX records, disposable domains and role addresses such as info@ first.

What ABV.bg's server says about a missing mailbox
The reply that matters is the one to RCPT TO, the step where the checking server names the recipient. ABV.bg answered our made-up abv.bg address with 550 5.1.1 <…@abv.bg>: Recipient address rejected: User unknown in virtual mailbox table. A 5xx code at that step is a permanent "no such mailbox", which is the same answer a real message would get, so SimpleVerifier marks the address invalid with the reason "Mailbox not found". A 250 at the same step means the mailbox exists and comes back valid.
Before trusting a "valid", a careful verifier also offers a random address that cannot exist. ABV.bg rejected ours, so abv.bg is not a catch-all: a 250 for your address is a real signal. Temporary 4xx replies (421, 450, 451) are about the connection, not the mailbox, and come back risky with "Server would not confirm" rather than invalid. Hard bounce vs soft bounce explains why that split matters.
ABV deletes mail after 24 months without sign-in
ABV.bg's terms require users to sign in at least once every 24 months. If they do not, Net Info deletes the archive of received mail. After five years without sign-in it may delete the whole mailbox and let another person take the username. A @abv.bg contact who has been quiet for two years may have an empty inbox, and one quiet for five may not exist.
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. Authenticate your domain and re-confirm old contacts before a first send.
Cleaning abv.bg addresses on a list
Because ABV.bg answers honestly, abv.bg is one of the domains where verification removes bounces before they happen. Drop the invalid results, keep the valid ones, and re-check the risky ones later: a temporary reply on one day often turns into a clear answer the next.
A valid result only means the mailbox exists today. Addresses on an old consumer list go stale as people stop using them, so re-verify before each large send to an aged segment; how often to verify an email list gives a schedule. Upload the CSV to the verifier and download the valid, risky and invalid rows as separate files.
Common questions

- Yes. @abv.bg answers mailbox checks one address at a time.

On 13 October 2026 the server rejected a made-up abv.bg address with "550 5.1.1 <…@abv.bg>: Recipient address rejected: User unknown in virtual mailbox table", so a missing mailbox shows up as invalid and the owner receives nothing.

- Why did an abv.bg address come back risky instead of invalid?
- Risky means the server didn't give a permanent answer during the check, usually a temporary 4xx reply or a timeout. It isn't proof the address is bad. Check it again later; ABV.bg gave a clear rejection for a missing mailbox when we tested it.
