Frequently asked questions
What happens when I reach my daily limit?
Requests above your plan limit are refused with a clear message, nothing is queued or lost, and your quota resets the next day. Need more volume? Pick a plan quantity above 1 at checkout: Ultimate Plan x 5 = 1M emails checked per day.
Do you store the emails I verify?
No. We return the result and keep no copy of the addresses you submit or of your lists. That is the whole point of MailTester Ninja: unlimited verification with no data left behind.
How does the key work?
Right after checkout you receive your key by email. Use it in the web verifier, the bulk app or the API. It stays active as long as your subscription is, and you can cancel any time from the My Account menu.
