What We Verify
Email Syntax
An email like user@@gmail..com is not just a mistake — it can mess up your analytics. We filter out such addresses right from the start.
Temporary Emails
We maintain our own database of temporary domains, which is constantly updated. You can automatically block registrations with such addresses.
Inactive Emails
Even if an email looks correct, it might not exist. We check DNS and MX records and attempt to contact the mail server.

Frequently Asked Questions
What happens after the trial package ends?
After reaching the trial package limit, verifications are paused, and a notification about insufficient balance is returned. To continue, you need to top up your balance.
Note that each package comes with its own API key.
How are the services billed?
You top up your account balance. Each verification request deducts a small amount, for example: $0.0005 per temporary email check. Funds are only deducted if the email format is correct. No charges for empty or obviously invalid addresses.
Can I top up my balance with Russian bank cards?
Of course! Although your account balance is in USD, the top-up amount will be calculated in Russian rubles.
What’s the difference between “temporary email check” and “full verification”?
A temporary email check is a fast domain lookup to see if it belongs to a known temporary mail service. Full verification includes checking DNS records, MX records, SMTP connection attempts, main domain existence, etc.

Can I use one API key for multiple domains?
Yes, you can. However, we recommend creating separate packages (and thus, keys) for each project — it simplifies statistics, management, and security.
How can I protect my API key from being stolen?
You can set allowed IP addresses or domains from which requests are accepted. This restricts access to only your servers.
