About BillionVerify
BillionVerify checks whether an email address can receive mail before you send to it. You can verify one address, clean a whole list, or connect the API to your own product.
What you can do
How billing works
A definite result uses one credit. Unknown, disposable and badly formatted addresses are free, and checking the same address again within 24 hours is free too. You get 20 free credits every day you use your account, up to 600 a month. They never expire, and you don't need a credit card.
What you'll find here
Practical guides on email verification, list cleaning, deliverability and cold email. Each article also lives on our main blog.
