Quick answer

Enter an email address and the tool checks its format, then performs a server-side SMTP handshake attempt to gauge mailbox reachability.

Key facts

  • Performs a real SMTP protocol handshake (HELO/MAIL FROM/RCPT TO) from A2Z Tools' server to attempt to verify mailbox existence|Based on this codebase, the SMTP check connects to Google's incoming mail server regardless of the target email's actual domain, so results for non-Gmail addresses may not be fully reliable|Also checks the domain portion of the email for basic reachability where applicable|This is server-side processing -- your email address is sent to and processed by the A2Z Tools server|Free to use, no signup required

What is this tool?

This tool checks whether an email address is properly formatted and attempts a server-side SMTP-level check to gauge whether the mailbox might exist, useful for a rough sanity check before sending to an address.

How to use it

Enter the email address, submit it, and review the result of the format and SMTP reachability check.
  1. Enter the email address you want to check.|Submit it for verification.|The server performs a format check and an SMTP-level reachability attempt.|Review the result indicating whether the address appears valid or invalid.

Example

Example: entering a syntactically valid address like "[email protected]" triggers a format check followed by an SMTP-level reachability attempt from the server.

How it works

The server first checks the email's basic format, then opens a real SMTP connection (HELO, MAIL FROM, RCPT TO commands) to attempt to verify mailbox existence; based on this codebase, that SMTP connection targets Google's mail server regardless of the checked email's actual domain, which is a real limitation for verifying non-Gmail addresses accurately.

Common use cases

Doing a quick sanity check on an email address's format before saving it.|Getting a rough signal on whether a Gmail address might be reachable.|Catching obviously malformed email addresses.|General email hygiene checks before bulk operations.

Benefits

Free and provides both a format check and an attempted deeper SMTP-level check in one tool.

Limitations

Based on direct code inspection, the SMTP handshake in this tool connects to Google's mail server regardless of the target domain, which means verification accuracy for addresses at non-Gmail domains may be unreliable; many mail providers also block or rate-limit this kind of external verification probe, which can produce false negatives; this tool does not guarantee that a mailbox is actively monitored or that email sent to it will be read.

Privacy & your data

The email address you enter is sent to and processed on the A2Z Tools server, which attempts a real SMTP-protocol connection as part of verification -- this is server-side processing, not browser-only.

Frequently asked questions

How accurate is the verification for non-Gmail addresses?
Based on the code, the SMTP reachability check connects to Google's mail server regardless of the target domain, so results for non-Gmail addresses may not be fully reliable -- treat results as a rough signal, not a guarantee.
Does this send a real email to the address?
No. SMTP verification only issues protocol-level commands (like RCPT TO) to probe reachability without actually sending a message.
Is my entered email sent to a server?
Yes. Verification requires a server-side SMTP connection, so the email address you enter is processed on the A2Z Tools server, not purely in your browser.
Is this tool free to use?
Yes, it's free with no signup required.
