I usually use mailinator.com for this purpose. In the past I found other similar services through Google search, but certainly didn't find yours. Probably working on your website SEO will increase your organic sign-ups. One thing I love about Mailinator is that all inboxes are public, this completely removes the overhead of creating a new email even in a disposable email service like yours. So probably something you may check for your product. Congrats for the achievement!

Mailinator addresses (including its random domains) are somehow banned on ~90% of sites that I've recently tried it on.

Other, smaller anonymous mailboxes tend to work though. So it's a rare market that shows the opposite of "too big to fail".

I appreciate mailinator, but mailinator’s domains are blocked in a lot of sites online; I know from experience some of their paid business is from companies using it for internal testing, which is far from great, and won’t sustain long-term, most likely.

Hats off to 33mail, though! Try not to get blacklisted.

I don’t see how 33mail would get blacklisted.

Mailinator allows sending emails, but this is to only receive emails.

The reason Mailinator is blacklisted in many sign up processes is because websites want to have users real email addresses, not disposable ones they don't care about.
