I'm always a little suspicious of these services. People use them to create throw-away accounts, which they abandon after one use. Those accounts remain active and are useful for botting (vote manipulation, comment spam, etc). Whoever owns the email domain can do a password reset to do an account take over.

I'm curious about the privacy policy. The title says that you don't have ads, but there's tons of discussion about sharing information with ad partners.

The only feature temp mail service should focus on having tons of domains. Many temp mail domains are blacklisted. only way to get around is rotating the domain name everyday. I will give it a try.

This is what the top sites do, e.g. temp-mail.org And they also don't allow you to view all the active domains which helps against getting blacklisted quickly

That's not really true because they used to have the same mail server so if you found one domain, then you could easily find the rest of the domains too.

Yes, just like all other email providers nothing is encrypted and you could totally look at the emails.

The difference here is though that there's nothing of value.

If I wanted to use this for malicious intent, then I think the most valuable thing I could get away with would be a 5% discount coupon.

I like that you bring this stuff up though as it could perhaps be good to mention this on the site down at the FAQ so people don't think I'm doing something shady with the service since there are no ads.

I wouldn't call it "easily" as you need a way to reverse lookup for all MX hostnames that resolve to a given IP address. Obviously they can rotate the IP address too, to further complicate things.

They use the same IP and their domains are all listed here: https://verifymail.io/domain/carspure.com

I have to admit that they have improved though as earlier they were all using the same MX records, now at least each domain has its own.

The fact they constantly have to rotate to avoid blocks is because they are used for abuse and are attempting to essentially attack network services.

Something like private aliases attached to a real account you actually have adds privacy, but retains accountability. (You can create aliases on Proton, Fastmail, Outlook, etc. but they are attached to your real account so abuse is manageable.) A service rotating temporary domains to avoid services blocking them is a malicious attacker, and should be treated as such.

Yeah the first one I learned about was mailinator and it worked for a good while but I think throwaway email services get blacklisted pretty quickly now, at least among people who don't want you to use them for whatever reason.

I find it amusing that a .org site (temp-mail.org) has ads all over it while a .com site (temporarymail.com) does not, given that .org was mostly used by non-profits while .com is intended for commercial use.

Non-profits still have bills to pay...

I don't agree with this and I think the right approach is to simply not require visitors to give up their email accounts if they don't want to.

If you want to block a malicious attacker, then you can use a captcha.

A serious malicious attacker wouldn't have a problem paying a few dollars to buy a domain, creating a catch-all address and if he wants to take it one step further he can even have it look like a legitimate email service.

Disposable services are ad blockers for emails.

Kind of compromises the mission alignment and trust though if it's through ads.
