Use case
Validate numbers before your outreach goes out
Sending to a number that isn't on WhatsApp wastes a send, hurts your delivery rate, and can flag your account. Check the list first, message only the numbers that will actually receive it.

What a bad list costs you
Wasted sends
Messages to numbers that were never on WhatsApp go nowhere.
Lower delivery rates
A high failure rate makes future sends look suspicious.
Flagged accounts
Repeated failed sends is exactly the pattern WhatsApp flags as spam.
How it works
Upload your outreach list or call the API
We check each number against WhatsApp
Message only the numbers that are live
Real-time
Sub-100ms per number, so you catch invalid numbers before they hurt your bounce rate, not after.
195+ countries
Just add the country code. Coverage is global by default.
Organized in batches
Every check is saved to your batch, so you never pay to validate the same number twice. Never sold.
