Short answer

How can I use my AI to check if emails are valid?

Your AI uses the verify_email tool to ping email providers and confirm an address actually exists. This keeps your sender reputation clean by catching typos and dead accounts. You'll see exactly which addresses are safe to use and which ones to toss.

The results.

Where your data ends up.

The AI processes your lists and categorizes the results based on their status.

VALID

Ready for outreach

The AI identifies confirmed, active addresses. You get a clean list of targets that won't bounce.

INVALID

Remove from lists

The AI flags dead or non-existent accounts. You can safely delete these to protect your domain.

RISKY

Handle with care

The AI catches catch-all or suspicious addresses. These are flagged so you can decide if they're worth the risk.

HUMAN

Manual review needed

The AI flags edge cases or ambiguous results. You decide whether to keep these or skip them.

The workflow

What your AI does when the list arrives.

Your agent takes over the repetitive task of checking every single line in your contact list.

  1. Ingest contact data

    Your AI reads the email addresses from your provided source, like a spreadsheet or a CRM export.

    verify_email
  2. Run validation checks

    The agent runs each address through the verification engine to check syntax and domain existence.

    verify_email
  3. Categorize results

    The AI sorts every address into clear buckets like valid, invalid, or risky based on the check.

    verify_email
  4. Report findings

    Your agent summarizes the health of your list and highlights the specific addresses that failed.

FAQ

How this task behaves.

  • 01

    Can the AI automatically send emails once they are verified?

    No. The AI only checks if the addresses are valid. You still have to use your own outreach tool to send the messages.

  • 02

    Will the AI delete invalid emails from my original spreadsheet?

    No. The AI only reads the data and reports the results. It won't change or delete anything in your original files.

  • 03

    How does the AI know if an email is a 'catch-all'?

    The verify_email tool checks the mail server response to see if it accepts all mail sent to that domain.

  • 04

    Does this work with any email list?

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

  • 05

    Can the AI fix typos in email addresses?

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