Hello there, When you are tired of fake registrations using disposable email addresses like from mailinator, trashmail, temp-mail, email-fake, etc, you may want to block them all. I created a free, public API to detect domain names from those fake mail service. Check it out at https://www.istempmail.com/ You can check up 10 requests per minute, no registration required
Cool business idea , cheap prices but I don't like sharing the emails address that I collect with someone else. There are similar services online, and if your doing some research you will find out they will steal your email address and either use them themselves or sell the data. To avoid confusion I'm not saying that's the case with your service, Its just whats happening with similar services.
