Yes, I have created multiple aliases for the same website with Addy and didn’t have any issues. That said, I have probably less than 20 Addy aliases in total (not for the same website).
Yes, they have. The Proton agents I have corrected verified the information with their colleagues and superiors, and admitted that I was right.
From my experience, it’s common for Proton Support to copy and paste their ToS. This is something I don’t mind, as long as it’s accompanied by commentary. If it has no commentary explaining, I will ask for clarifications.
I personally don’t like it when they tell me to just check their ToS, and are incapable of quoting me the specific part that applies to my question. That has happened to me before with Proton’s support team, but also other services.
Proton didn’t allow me to create multiple aliases for the same website, so no, I have not experienced this. But that doesn’t mean it couldn’t happen. Proton’s abuse trigger may not be promted with simulaneous emails from the same website if it happens a couple of times. But after a while, it could.
There’s a forum I belong to, on which I am subcribed to a dozen plus threads that have constant activity, every single day. I get notified via email every time there’s an update on those threads. Within a week I can easily receive 30 to 50 email notifications from a single thread. And remember I am subcribed to at least a dozen. I only have one account on that forum, but imagine if I had 3, and that I used a Proton Pass alias for each.
That means that I would get 100+ email notification on each alias at the same time, every week. That could easily ring Proton’s alarm.
I have no idea, and I’m sure we’ll never know because I’ve asked Proton, and they told me they couldn’t tell me because they don’t want people to game their system, which makes sense.
The context in which I asked how their system works is by asking how they could tell the different between aliases that are used just for emailing, and aliases that are used to manage accounts.
Because, as I’ve explained in my Substack post, you’re allowed to create 10 different aliases to email 10 different Gmail addresses (same domain). But you’re not allowed to create 10 aliases to manage 10 Google accounts (also same domain).
How can Proton tell the difference? I don’t know, but they can. I know because I have created multiple aliases to email Gmail addresses, and it didn’t trigger anything because it’s allowed. Those aliases are still active.
