Short answer

Can my AI check if email addresses are valid?

Yes. Your AI uses the Findymail MCP to run real-time checks on any email address you provide. This ensures you only reach real inboxes and avoids spam filters. You'll see exactly how the validation works below.

The results.

Where your data lands.

The AI processes your lists and organizes the results into these categories.

VALID

Safe to send

The AI identifies addresses that passed all checks. You can move these directly into your outreach campaigns.

INVALID

Remove from list

The AI flags addresses that are dead or non-existent. These are stripped out to protect your sender score.

RISKY

Handle with care

The AI catches catch-all or suspicious addresses. You decide if these are worth the risk before sending.

HUMAN

Manual review needed

The AI flags edge cases it can't definitively prove. You step in to verify these specific contacts manually.

The workflow

What your AI does when the list arrives.

The AI acts as a gatekeeper between your raw data and your email provider.

  1. Scan the list

    Your agent reads through your provided spreadsheet or contact list to identify every email address that needs checking.

    verify_email

  2. Run validation

    The AI executes a check on each address to confirm the domain and mailbox actually exist.

    verify_email

  3. Filter results

    The AI separates the good addresses from the bad ones based on the verification status.

    verify_email

  4. Report status

    The AI presents a clean summary of which contacts are safe to use and which should be deleted.

FAQ

How the verification works

  • 01

    Will the AI automatically send emails for me?

    No. The AI only verifies the addresses. You still control the actual sending through your email service provider.

  • 02

    Does the AI delete my original contact lists?

    No. The AI reads your data to perform the check, but it does not modify or delete your source files.

  • 03

    Can the AI fix a typo in an email address?

    No. The AI identifies if an address is invalid, but it won't guess what the correct spelling should be.

  • 04

    What happens if an email is marked as 'catch-all'?

    The AI flags these as risky. It's up to you to decide if you want to attempt delivery to those addresses.

  • 05

    How does this protect my domain?

    By using the tool to catch invalid addresses before you send, you prevent hard bounces that damage your reputation.
