I've tried the Catch-All feature from ProtonMail and the general alias approach (username+alias@....) so I could have aliases like facebook@mydomain which would point to my ProntonMail address so I can track and manage that alias.

Why the Catch-All doesn't work for what I want to achieve?

I want to provide an alias to each service that requires an email to register or contact like a Service which can be done with the Catch-All feature but once enabled, it can be used by spammers to send emails to the service@mydomain that I setup but also to everything else to *@mydomain and ProtonMail doesn't provide a way to track those addresses and reject/deactivate them which makes the life of spammers really easy as they only need to know my @mydomain and then send emails to me as they want like spammer1@mydomain spammer2@mydomain, etc which makes it impossible to block it with filters unless you set a list of whitelisted email addresses which is not easy because everytime I create an account in a service I need to update the list.

Why the general alias approach (eg. username+alias@mydomain) doesn't work for what I want to achieve?

Much of the same as the Catch-All feature but here the spammers need to know my username name and domain which is really easier. Lets say I have username+service@mydomain and ther service shares that address, with a bit of a regex that can remove everything between + and @ which will give them my username@mydomain email address and them start to send spam emails and you can't track which was the original email address that was sold or who sold it, not to say that if the spammers start to send emails to username+whatever@mydomain, I would have to deactivate the whole address username@mydomain to reject all emails which is not optimal as I would have to change all services where I used username+*@mydomain.

In both cases, if you plan to use those features to track who sells your email address, it will not workout as shown by the examples if the spammers do a bit of automation.

Final thoughts
I think the idea of disposable email aliases with proper management feature like create, randomize, disabling/expiring it so the server rejects all messages for those will definitely give my ProtonMail email addresses full privacy.

The most voted feature, more voted on than ProtonDrive

I currently use SimpleLogin and love it. However, it would be better if it was a built-in function in ProtonMail.

nice idea, interesting,

Totally agree! Besides, even when you start replying an e-mail and, for some reason, need to save the draft to resume later, when you pick it up to resume it, the '+alias' will be removed from the "from" field, putting in risk you sending the e-mail without it even you don't pay attention.

Would like to not have to use anonaddy anymore

Similar to the links provided in the original post, fastmail's catch all Aliasing works well for this https://www.fastmail.com/help/receive/aliases.html and https://www.fastmail.com/help/receive/alias-catchall.html . I understand the concerns around catch-alls, but the ability to set specific aliases with regex in the them would be excellent.

Example: alias*@<customdomain>.com as a redirect to a primary address.

Also having normal aliases: <name>@<domain> and having <alias>@<domain> seems like it really should exist without having to set up one of a very limited number of addresses.

Similarly, an NYM like service would also solve the problem much of the time.

An option to generate a random address (this could be a long address so shouldn't be a worry to waste the email availabilty) similar to aliases. Similar to anonaddy but without having to pass emails through a third party

trashmail by Stephan Ferraro is a wonderful service, 2500 alias with al the features you mention, and more. right click context menu in most platform, very cheap. and Wonderfully supported by author.

this is something I can only dream of. No need to use anonaddy ever again

Currently, you can only send from alias addresses by replying to an existing email to that alias. Being able to directly send from an alias would make this feature a lot more useful.

Being able to manually add alias address to Settings > Addresses/Users without it counting towards the total of allowed additional addresses would also be helpful.

+1

I will pay for this feature. get some new domain names for disposable generated emails and that way protonmail.com, protonmail.ch and pm.me can still be official email usernames while another domain names can be used for an disposable email

I don’t understand where is the problem with e.g. having one slot for changeable, randomly generated address for paid accounts, that can only receive email.
Would be great to be able more securely exchange contact information with friends via chat or pm on social network sites and forums that mishandle data as well as to sign up on such sites.

Disposable addresses - like temp@nym.proton.com - ala Hushmail.

I know you can create several email addresses but they are permanent and cannot be changed.

Before using protonmail I was subscribed to startmail. It is a great service but it lacks features and I don't like the design. Which is why I moved to Protonmail, which I like more.

However, there is one big feature I miss for this. With startmail you can create a limited amount of permanent aliases like test@use.startmail.com instead of test@startmail.com (the main address).

Those permanent aliases can be removed and created as you see fit, but you can only create them once. So if I create test@use.startmail.com and late delete it, then nobody else nor I myself can create the same test@use.startmail.com alias again.

In addition, you can create disposable aliases. They also use the @use.startmail.com domain but they can be set to be valid for as little as 15 minutes to as high to several hours. Then they automatically expire.

This would be something, I would really love to see with protonmail. Many times you need to create an account somewhere or want to try something.

That means, that you will get spam mail every day and many times the unsubscribe link won't work. It is fine with a free mail account. You can just make a new one. But if you pay 150 USD a year, like I do, than I would want to keep my email private and not to be spammed.

Fix the @#$!Ng "+" sign to a dot or dash for cripes sake. We've only been asking for it, like +4years.

Paid user

Dear all,

When shopping on-line, a new proton-email address can be created, but it is a "permanente" email address.

Could this temporary "disposal" email address be automatically deleted according to an "expiration date" selected by the user? Hence, the user could create other "disposal" email address (alike startmail).

This is what SimpleLogin offers which is a email alias service that protect users from email spam from databreaches. I would like to see protonmail offer this even if it is for paid users only. Even if this means protonmail gets a few new domain names such as pmalias.com, protonmailalias.com, pmalias.me, etc and users cannot make accounts using these domain names but can make as many alias accounts as they want with these domain names.

I understand you can already have "aliases" such as 5 email addresses for a paid account or use the "+" but this does not protect protonmail users for email spam if their online accounts get hacked.

So if your protonmail username is john@protonmail.com you can create aliases such as...

facebookfever@pmalias.com
john232@pmalias.com

And these aliases does not reveal the true owner of these email addresses if the website they have an account on has a databreach.

Me gustaría poder editar el usuario, o que aparezca un alias corto, que sustituya al nombre de usuario en un mail, ; o bien, que el autorelleno te visualice el nombre de usuario largo, para ganar tiempo, gracias. 1 saludo
