The 10minutemail is problematic in a sense, that you can lost access to the emails? Or you have to store a link to access them?
With simple login, it is possible. You just delete after use.
There maybe the distinction of the aliases could be problematic in your email tool? Not impossible, but not that convenient.
10minutemail/tempmail is what I consider "one-time use". Yeah, one literally uses it for short period of time to verify an email address for example and to not use it in future. However, many such services offer you an ability to open that mailbox later, but with a constraint of deleting letters one hour after receiving them.
