Questions
How many emails can I check at once?
Up to 500 at a time, and up to 1,000 every 10 minutes. For bigger lists, contact us.
Do you keep my list?
No. The addresses are only used for the check and are not stored.
Do you email the people on my list?
No. We only look up each domain and its mail servers.
What does Risky mean?
The domain can get email, but something is off: a throwaway inbox, a likely typo or no mail server set up.
