Questions before you start.
Ask us on the chat if yours isn't here. A real person answers.
What does Catch-all mean?
The domain accepts mail for any address, so no checker can confirm the person exists. Send to these carefully, or leave them out.
Do I need an Outreach plan?
No. Email Verifier credits are sold on their own, and work with Outreach if you have it.
How much does it cost?
Your first 100 checks are free. After that, credit packs start at 5,000 checks. See the pricing page for every pack.
How long are results kept?
60 days. Download anything you want to keep longer.
Does verifying email the people on my list?
No. The check asks the mail server whether the address exists, without sending anyone an email.
What bounce rate should I aim for?
Under 2%. Above that, stop and clean the list, because a high bounce rate tells filters you don't know who you're emailing.
When should I verify a list?
Right before you send. People change jobs and companies close, so a list decays while it waits.
Everything for cold email, in one place.
