Frequently asked questions

A catch-all domain accepts mail for every address, existing or not, so a check cannot confirm a mailbox there. This task returns these addresses as risky with the verdict Catch-All.

This task compares each domain with a list of disposable email providers kept up to date by MailTester Ninja, and returns these addresses as invalid with the verdict Disposable.

This task adds no charge of its own: you only pay the Apify usage of the run, which stays tiny. It needs a MailTester Ninja key, either a free API token (50 checks a day) or a plan from $6.99 a week for 100,000 checks a day.

MailTester Ninja keeps no copy of the addresses you verify. The results of this task stay in your own Apify storage, under your control.
