I think it depends. If it’s for your own personal use, in the sense that you need to mark events that you don’t intend to share with anyone, then yes, a calendar is a must.
However, for me, if I need to share calendar dates with other people, Proton and Tuta’s calendars are not useful to me because they share my email address with the recipient, which is something I don’t want.
99% of my email exchanges are with email aliases. Not with my Proton or Tuta addresses. If I share a calendar, it’s not going to expose my alias, which I would be fine with, it exposes my Tuta/Proton address, which I don’t want.
I hope that in the future, Proton and Tuta find a way to hide the address behind a calendar. Recently, a business asked me to share a calendar for the event of our meeting and share it with them. I had to improvise. I created an event with Fossify’s Calendar, downloaded it as a file, and sent the file to the business as an attachment. All to avoid sharing my Proton or Tuta address. They didn’t say anything so it was fine. But in the future, I could see this becoming a problem.
It is annoying to have to do that, and services like cal.com are a good way to get around that issue (you let them book a date themselves and both parties receive an email).
But then, I always end up joining the call with a totally different email address than the one in the calendar invitation (which would be a public email address).
At the same time, I do have people that are understanding of my concerns and are also fine planning an appointment with an alias email, they don’t really care.
I anyway do never trust the buttons in those emails. If I have a Google calendar invite at my company and use a Gmail box, then sure. If it’s an invite sent from a Yahoo, for a Google Meet and I do click on “yes” from a Tuta, then I have no guarantee that the thing will really work.
Hence I always fallback into opening the link of the meeting into a new page or just communicate with some chat with the concerned people.
Indeed. I had sent an invite from Proton to a Hotmail user. The invite would have showed up with a “RSVP” button in the web version of Hotmail (Outlook), but the invitee actually checked it on their iPhone in the default Mail app and that one didn’t display the interactive element at all so they didn’t know they were supposed to accept an invitation and they just deleted the email.
