Bulk Check of spam IPs and Emails

You can use our site to bulk check IPs and Emails for spam. The interface allows you to upload a list of IP addresses for verification in a file and download the result of spam check in a file with CSV or JSON format. How to use bulk spam IP or email check.

How is it calculated?

Checks limit — the number of IP and email addresses that have been checked.

As the example: if you send one API request that contains 2 IP's to check — this will be calculated as 2 checks because there were 2 IP's.

One API request may include up to 1000 IP's or emails.

When you choose API package, you are buying the number of checks for a needed period of the license. API package depends on the amount of the checks and period of license for which you can use these checks.
