How good is the proton ecosystem if I have multiple mail addresses and calendars?

Say I have [e-mail] and [e-mail], can I use one unified inbox, and can I use both addresses to send and receive calendar invites?

Moreover, how easy is it to combine my calendars with my work calendar?

I heard it's also not possible to sync contacts with iOS, is that true?

It's great for multiple mail addresses. I get mail from multiple domains all in my ProtonMail inbox. Very easy to send from multiple addresses as well.

You can also turn on catch all addresses where you'll get all mail sent to anything @yourdomain.com. Very handy to create unique emails for sites I don't want to have my emails I actually use with contacts.

I can't really comment on multiple calendars. I haven't experimented much with that and get all my invites sent to one address.

Don't know about calendars. They are one of the better ones for multiple address - there's a limit on the number of a) domains) and b) email addresses you can reply from (but no limit on the number you receive from, with a catch-all).

I think their different plans allow different numbers.

The one what doesn't have any limits other than bandwidth is migadu. But they don't support second fact properly, last I looked.

"second factor" (can't edit the above any more)

fastmail would be lot better.

I migrated from paid proton to fastmail years ago and still happy.

I pay for both, use them for different things, but to be clear, fastmail does not have the encryption features that ProtonMail does. Not a direct replacement if you’re interested in the privacy aspects.

What encryption features? GPG works with any email provider.

Any specific improvements?

I ended up switching to Fastmail after it being recommended here ages back, and it’s been fantastic.

I’ve also used Google Workspace, O365 or whatever MS calls it this week, and Proton as well as self hosting mail in the past.

I'm honestly shocked by how long I've been using Fastmail without having a single complaint to talk about.

Usually after using a tool for an extended period of time, there's gonna be some annoyance that you just have to learn to deal with. After five or so years of me using Fastmail, I can't think of a single thing that actually bothers me.
