Check If Email Exists

I think what this is telling you is that users don’t value giving you their email address for your free tools. They know why you want their email address, and they don’t want that, but they do want your tools. Maybe it’s time to charge money for those tools or change models? Maybe not give access until the email address is confirmed? Worth considering I guess. Idk the details. I do this all the time. Ads and malpractice have made giving out your email address risky business. If a user can give you a fake email and get what they want without giving you anything (subject to your ads or whatever you’re using their email for) that’s the logical thing for them to do.

Not judging or anything though I know my tone might seem that way.

You seem to be assuming there's no reason these tools need a login system at all. Assuming they do and they're storing some kind of state or data for the user, how do you handle forgotten passwords if the user can't receive an email? A second free tier for people who can't be bothered to add a recovery email is too much work for a tool that's free anyway.

To the parent: Just send a validation email during the onboarding process. Don't create the account until they validate. And DO rate limit the number of these sent to any given address and the number of signup attempts by IP / fingerprint. Captchas are also good, but just for slowing fakes down.

This is literally the same thing the person you're replying to suggested.

Is it that risky? Talking, at least, as a somewhat knowledgeable person, which is the target of such web tools.

I usually have no problem using my email address to sign up for things. And yes, I do know that emails will come.

Sometimes they are actually useful and I keep them. Often, I don't care and I just unsubscribe. I some not-so-common cases, it is spam, in which case I mark it as such and I am never bothered by it again.

Sure, it's a bit of extra work. But I would not classify it as risky business.

I was thinking risky in terms of cost/benefit.

The cost for me to give a fake email is very close to 0, and the risk of getting spam emails or who knows what is much higher in comparison so why bother giving anyone my real email address? I mean I do give it out from time to time (you can easily find it if you want) I’m just speaking generally.

You seem to be assuming “a lot of fake user signups” == “few real user signups.” OP only said the first. For all we know they also get plenty of real ones.

Weird. Same exact 5-word opening I was typing. I didn't see your post until I posted mine.
