Ask AI about this page

Short answer

Can my AI check if an email is real?

Yes. Your AI uses the EmailListVerify MCP to run SMTP and MX record checks on specific addresses. This confirms the mailbox actually exists and can receive mail without you manually testing it.

The results of a check.

Where every address lands.

The AI categorizes every address based on its technical validity.

VALID

Ready to use

The AI confirms the SMTP handshake succeeded. You can safely add these to your contact list.

INVALID

Dead addresses

The tool identifies non-existent domains or mailboxes. Your AI flags these so you don't waste effort.

RISKY

Proceed with caution

The AI detects catch-all domains or suspicious configurations. You decide if these are worth the risk.

HUMAN

Manual review needed

If the server blocks the check, the AI notifies you. You'll need to decide how to handle these edge cases.

The workflow

What your AI does when an email arrives.

Your agent handles the heavy lifting of network communication to validate the address.

  1. Identify the target

    Your AI extracts the specific email address from your chat or document.

  2. Check domain health

  3. Perform SMTP handshake

    The tool communicates with the mail server to see if the specific mailbox is active.

FAQ

How this task behaves.

  • 01

    Can the AI verify a whole list at once?

    No. This specific tool is designed to verify one email address at a time through your chat.

  • 02

    Will the AI send an email to test it?

    No. The tool only performs SMTP and MX record checks. It never actually sends a message to the recipient.

  • 03

    Does the AI change my contact list?

    No. The AI only reports the results of the check. You have to manually update your own files or tools.

  • 04

    What happens if the mail server is down?

    The tool will report that the check could not be completed. The AI will tell you the server was unreachable.

  • 05

    Can the AI fix an invalid email?

    No. The AI can only tell you if an address is valid or not. It cannot correct typos or create new mailboxes.
