Where your data lands

Once your AI runs the check, your data lands in these categories.

VALID

Ready to message

The AI identifies numbers successfully registered on WhatsApp. You can immediately move these to your outreach campaign.

INVALID

Dead numbers

The AI flags numbers that aren't on the platform. You can strip these from your list to save costs and protect your sender reputation.

REVIEW

Needs human eyes

If the status is ambiguous or the number format looks wrong, the AI flags it for you to check manually.

CLEAN

Updated lead list

Your final list is filtered and verified. You're left with only active, reachable contacts.

The workflow

What your AI does when the list arrives.

The AI takes your raw data and runs it through the 360dialog connection.

  1. Read the list

    Your AI pulls the phone numbers from your provided source, like a CSV or a Google Sheet.

    check_contacts

  2. Verify registration

    The agent checks each number against the WhatsApp network to see if an account exists.

    check_contacts

  3. Filter results

    The AI separates the valid WhatsApp users from the invalid ones based on the check results.

    check_contacts

  4. Report status

    The AI gives you a summary of how many contacts are actually reachable.

FAQ

How this task behaves

  • 01

    Can the AI send messages automatically after checking?

    No. This specific task only checks if a number is registered. You have to trigger the actual messaging separately.

  • 02

    Will the AI delete invalid numbers from my original file?

    No. The AI only reads your data and provides a filtered list or report. It won't modify your original source files.

  • 03

    Does this work with any phone number?

    The check works for any number, but the results depend entirely on whether that number has a WhatsApp account tied to it.

  • 04

    Can the AI fix incorrectly formatted numbers?

    No. If a number is missing a country code or is formatted poorly, the check will likely return it as invalid. You'll need to fix those manually.

  • 05

    How does the AI know which numbers to check?

    The AI uses the data you provide in your prompt, such as a list of numbers you paste in or a file you've attached.
