Hi I'm sorry I didn't see this before, but this text change is incorrect. You can see the original implementation here for the front end, and here for the issue alert email. (digests and metric alerts) We pass the query param mute:1 in the link and the front end reads that as "mute for me".

As far as I can see this hasn't changed since it was originally added so all emails would have the mute:1 query parameter. I think we left the text a little ambiguous on purpose because there are certain alert configurations where the only choice is to mute for everyone, like if it's set to notify a team (this may not be the correct example, it's hard to remember). If we really wanted to we could change it so as we build the emails it changes the text and query param, but we thought this was ok as is because when you do click to mute, there is a text banner that says either "You muted this alert so you won't get these notifications in the future." or "You muted this alert for everyone so you won't get these notifications in the future."
