There are a few really good ones, like the one mentioned, linshi-email.com, etc. The only difference is how often the receiving domains are updated. In order to get emails you need to update them frequently because most advertising companies keep a list of which emails are dissposable.

I use https://tempmailo.com/ for these purposes. They change domains frequently, emails come relatively quickly.

I use mainly diasp.org (currently hosting is down) and joindiaspora.com (new registrations closed)
