Results

Six clear results, each with a next step

No mail server jargon. Every address is sorted into send, review or remove, with the reason attached.

Valid Send

The mailbox exists and accepts mail.

Catch-all Review

The domain accepts every address, so no single mailbox can be confirmed.

Role address Review

A shared inbox such as info@ or sales@. Real, but often filtered.

Unknown Free

The mail server did not answer in time. You are never charged for these.

Invalid Remove

The domain or mailbox does not exist. Mail to it will bounce.

Disposable Remove

A temporary inbox that stops working within hours or days.

How it works

Five checks on every address

Nothing is ever sent to the person behind the address.

  1. Format

    We read the address the way mail servers do and catch typos like gmial.com.

  2. Domain

    We confirm the domain exists and has live DNS records.

  3. Mail server

    We find the servers that receive mail for the domain and check they respond.

  4. Mailbox

    We ask the server whether the mailbox exists, then hang up before any message is sent.

  5. Verdict

    We add our disposable and role checks and give you one clear result.

FAQ

Questions people ask before they upload

Something else on your mind? Ask us and we reply within one business day.

Do you send an email to the addresses you check?

No. We talk to the receiving mail server and ask whether the mailbox exists, then close the connection before a message is sent. The person behind the address never hears from us.

Why do some addresses come back as catch-all or unknown?

Some domains accept mail for every possible address, so their servers will not say whether one mailbox exists. Others answer slowly or refuse checks. We label these clearly rather than guessing, and we never charge for an unknown result.

What happens to the lists I upload?

Your lists are used only to run the checks you asked for. They are deleted automatically 30 days after the check finishes, or straight away if you delete them yourself. We never sell, share or reuse your data.

Which file types can I upload?

CSV, TXT and Excel (XLSX) files. If your file has several columns, BounceBell finds the email column for you and keeps the rest of your data as it is.

Why do you ask for a work email to sign up?

Free checks are for businesses trying the service. Asking for a company address keeps the free tier from being used to test stolen or scraped lists.

Who runs BounceBell?

BounceBell is built and run by Astrizon Technology Solutions Pvt Ltd in Bengaluru, India, the team behind DATAVICS and IPzentra. Read more about us.
