Terms of use
Last updated: 11 November 2026
Using Email Chekkr
You can use Email Chekkr to check email addresses that you have a lawful reason to hold, for example your own customers, subscribers or leads. Don't use it to build lists for spam or to break any law, including anti-spam and data protection laws.
What the results mean
Results are an estimate based on the address format and public information about its domain. Email Chekkr doesn't confirm that a specific mailbox exists. A "valid" result does not guarantee delivery, and an "invalid" or "risky" result may occasionally be wrong.
No warranty
Email Chekkr is provided "as is", without any warranty. We're not responsible for losses that come from relying on its results.
Availability and changes
Single checks are free. Bulk checks are free during early access. Features, limits and pricing may change. Paid plans will have their own terms shown before you pay.
