Don't take it the wrong way, I wish you all the best but I also hope this particular project won't see any significant adaptation :(

No offense, but why block those addresses?

Because some services have sensitive information and need a reliable way to contact you. If you use my service and attach your credit card to pay for it, and used a disposable email to sign up with and your account gets breached, who's fault is it that I couldn't email you and let you know?

Sure if it's some throw away service that doesn't have such sensitive information, that's fine, but there's many reasons to use such a service.

> who's fault is it that I couldn't email you and let you know?

The user's fault; they are knowingly trading that risk for protection of their privacy. That says a lot for how they regard the service in question.

What about rejecting ISP-issued e-mail addresses? Those are also ephemeral, for those who use them.

What about Yahoo! / Outlook.com / Gmail addresses? in the vast majority of cases people using those have no 'hold' on them and their accounts can be suspended at whim.

Domain-related addresses can be lost if the registry decides to hike the domain prices beyond affordability, such as with the 1000% increase in Uniregistry gTLDs later this year.

Where to draw the line? All e-mail addresses are temporary.

That makes sense, thanks. My line of thought was that if someone is using a disposable address they probably aren't going to respond to marketing anyways - they're just checking out your service.

Sometimes people use them for bots to create accounts.

Also makes sense. Thanks!

There's a reason I'm using a disposable address for your service. A much better user experience would be for you to allow me the option to try out your service before giving you my email.

How much does it cost to get my temp email service white listed?

I'll never accept payment for those cases. It defeats the purpose.

Disposable email addresses exists precisely because we don't plan on returning. Some websites tried to block disposable addresses already, I just went somewhere else.

Then you are an arsehole, plain and simple.
