How to verify email deliverability with your AI

Connect Icypeas to your AI client once. From then on, your agent handles the heavy lifting of validating contact lists.

Ask AI about this page

Short answer

Can my AI check if an email address is real?

Yes. Your AI uses Icypeas to ping mail servers and confirm if an address is active. You'll get a clear list of which contacts are safe to message and which are dead ends.

Where your data lands.

The outcomes of your check.

The AI processes your list and organizes the results based on their status.

VALID

Ready for outreach

The AI identifies confirmed addresses. You can move these directly into your next campaign.

INVALID

Remove from lists

The AI flags dead or non-existent addresses. These are pulled out to protect your sender reputation.

RISKY

Handle with care

The AI catches catch-all or suspicious addresses. You'll know which ones might still bounce.

HUMAN

Manual review needed

The AI flags edge cases it can't resolve. You decide how to handle these specific contacts.

The workflow

What your AI does when the list arrives.

Your agent takes over the tedious task of checking every single recipient.

  1. Identify targets

    Your AI pulls the list of email addresses you want to check from your source file or sheet.

    fetch_results

  2. Run validation

    The agent sends each address to the verification engine to check its status.

    verify_email

  3. Analyze status

    The AI looks at the response from the verification check to determine if the email is safe.

    fetch_results

  4. Report findings

    The agent summarizes which emails passed and which failed so you can act on it.

    fetch_results

FAQ

How this task behaves.

  • 01

    Can the AI fix a typo in an email address?

    No. The AI only checks if the address provided is valid. It won't guess what the correct spelling should be.

  • 02

    Will the AI send the emails for me?

    No. This MCP is only for verifying if an address exists. You still need to use your own email tool to send messages.

  • 03

    Does it work with any email list?

    Yes, as long as you can provide the list to your AI client via text, a sheet, or a file.

  • 04

    Can the AI delete my original contact list?

    No. The AI only reads the data to perform the check. It doesn't have the ability to delete your files or records.

  • 05

    How does it handle catch-all addresses?

    The AI identifies them as risky, but it won't automatically decide to skip them. You have to tell the AI how to treat those results.
