How to block disposable mails
Using our free email verification API, you can easily block fake emails and block disposable email addresses!
You have a sign-up form on your website, to prevent spamming, trolls, and perhaps only allow a trial version or freebie per user.
The user doesn't want to give you his real e-mail.
There are many many websites, where users can instantly generate a random e-mail, for example: [email protected]
They give you this disposable instantly generated e-mail instead of their real one!
As soon as they sign-up, or get whatever they want from you, they never bother about that e-mail address again.
Even if you require e-mail validation, they can simply click your link when it is received, and then never read that e-mail again.
You now have the fake e-mail [email protected] in your database, and the user can easily repeat the same thing hundreds of times.
And with literally hundreds of different domains.
What are you waiting for?
It's of course fine to allow temporary disposable e-mail addresses if you want to, but it really depends on your target demographic and what services you offer.
If you have a voting system, comments, or allow free trials based on e-mail addresses, it's not as simple. Are you okay with the fact that it's so easy to generate fake e-mail addresses, and download unlimited trials, vote multiple times, or difficulty to block spammers and trolls?
But, if they can always generate unlimited e-mail addresses via Hotmail or Yahoo, why should you care? There is much bigger work involved in generating "real" e-mail addresses than fake disposable temporary e-mail addresses. Many time, if it's too much of a hazzle, they will eventually stop trying.
There are hundreds of domains being used for temporary disposable e-mails, and it's a big job to blacklist them all, and new ones are being added regularly.
Here are a few domains which our API recently blocked automatically:
