I doubt that a meaningful number of users creates new accounts every 7 days just to avoid paying. Setting up a new account is usually enough work that it is not worth it. But if that is the case for your service, here are three things from the top of my head that might even work. If instead you just block disposable email addresses, I might as well look somewhere else.

* Reduce the trial period for users with a disposable email.

* Don't allow data import/export so that creating a new account is more work.

* Reduce cookie lifetime so that a login is needed more often.

Thanks, the first idea is a really good one for our use case. (the other ideas won't work unfortunately)

And yes, it is not a meaningful number of people that do so, but over time this is very ugly and frustrating (as it requires manual intervention) and you block the disposable Email provider they used ...

This seems like an ego issue honestly. Like you feel like you are being taken advantage of. If only a very small numbers of users are doing this then I don't see it worth the dev time to block the email providers they use possibly hurting valid customers. Just leave it alone. I use Relay for services I genuinely pay for but don't want to give out my email address in case of leaks.

Your free trial is too generous.

Suggest using the Standard plan but with significant rate limiting. Like 5/day.

If they want to remove that, enter credit card details which you verify.

You can still have the trial expire and the credit card isn't ever charged; but you can track people on trials more easily.

I think that someone who doesn't want to give their real email address to try out a service is even less likely to trust an unknown service with their credit card number. There are just too many "free trials" that promise to not charge your credit card and then make you jump all sorts of hurdles (e.g., having to call) to cancel the free trial.

I think you'd be surprised. Credit cards are easier to dispose of then email addresses, and they offer greater protection with fraud and billing dispute processes. Some banks even offer virtual cards that let you set limits on duration or amount.

And that's OK. The problem as I understand it is that people are signing up with disposable email addresses, using the API key they receive for 7 days, and then signing up again. They are leeches, exploiting the generous free trial.

If they stop signing up, no problem. Other people who sign up with a disposable email address can test within the restrictions, and once they trust the service have a choice to enter card details or not. If they are planning to do business with the service, they're going to have to trust it with card details.

I mean, if its not having a notable impact except emotionally, maybe its better to just let it be?

Missing the forest for the trees and all

[karussell]

Probably. But if we wouldn't block certain disposable Email providers since years, maybe this would be already dozens per month.
