*Unlimited* Disposable Email Aliases
(to vote for unlimited alias, visit https://protonmail.uservoice.com/forums/284483/suggestions/45394132)
Startmail explains it perfectly. They offer unlimited disposable aliases, which expire within a given amount of time. They also offer custom aliases which can be saved and used indefinitely.
It is the disposable alias which will help protect privacy, when submiting an email to an untrusted recipient. After all, how much privacy do we have if our fixed emails become the foundation for building and selling our marketing profiles, just as is done by gmail. We limit personal activity virtual trails by disposing of aliases for casual uses. But, unlike custom aliases, which build on our identifiable original email address, disposable aliases divert from our true email identity by utilizing a sub-domain created for this specific purpose, such as: xxx@tda.protonmail.com (tda = temporary disposable alias)
You avoid abuse by limiting disposable alias creation on a daily basis. Perhaps 5 max per day.
Here is Startmail's explanation:

The Blur service (by Abine) also offers a "masked mail" free service. But their service is not encrypted:

The way sneakemail.com does it makes sure your real email is never revealed, even when replying to emails.
Here is how it works
1. create to generate a random email address and give the a name/label.
2. Give the random email some evil person.
3. When evil person writes to it, Sneakmail sends it to you with a new reply-to email address.
4. When you write to this new reply-to email address, it will be sent to sneakemail, and they know they have given it to you, so they replace your from email address with the one generated in step 1.

Gmail has this feature where example.x@gmail goes to example@gmail regardless of what x is. I think this falls under this feature and would be awesome

Tobias, the problem with this is that it gives away your identity as the people you give it to can figure out what your base e-mail address is. Aliases should enable you to send e-mail from any of your aliases as if they were independent e-mail addresses, without any way for the recipient to tell that this is an alias.
I think it is much more important than using up existing usernames.
