Rainloop vs SoGo

Which is better? Why? Why not?

These apps serve different purposes, so I don't think one can really answer the question without knowing the use-case.

My suggestion is if you only care about webmail, then Rainloop wins. It's quicker, nicer interface (IMO), intuitive, etc. If you however also want to manage a calendar and contacts, then SOGo is likely the better one as Rainloop does mail and contacts only, no calendar or anything like that. And even for contacts, it's differently managed - Rainloop simply stores them, but SOGo "hosts" them so they're also accessible via CardDAV protocols into apps like Contacts on macOS or iOS, Calendar on macOS, etc.

Basically, Rainloop is a webmail client whereas SOGo is what's called "groupware" as it will sync contacts, calendars, tasks, etc. in addition to the mail client role.

If you elaborate on your use-case, then people can probably give you a more accurate answer. Hopefully the above helps in the meantime.

@d19dotca Your answer was perfect. I wanted to get other's feedback on their preferred client on their use cases.

Only recently did Calendar and aliases start working reliably in the Cloudron SOGo package. I think mailbox sharing still doesn't work but it's in our TODO list.

Because of this, my personal and cloudron.io email setup doesn't use SOGo. @nebulon and I both use thunderbird for day to day use. We have a rainloop installation just to manage our mail filters (in my personal install, I use roundcube for this instead just for variety ). This too was because thunderbird's sieve extension was previously not working with Cloudron Email. That problem has since been fixed but thunderbird's sieve extension is not very user friendly, so we stick to rainloop/roundcube. For calendar/contacts, we use our Nextcloud's caldav/carddav. Both Gnome and Thunderbird, have excellent integrations for caldav/carddav. One important consideration here is that we moved out of another provider which let us export carddav. Nextcloud has an importer that works, I haven't tested out the importers of other apps.

Shared mailboxes (like sales@, support@) was quite complicated with thunderbird (because the mail read/unread flag is not per-user). You also have to configure thunderbird to bcc replies so that the other user can see the replies. Recently, we have moved our shared mailboxes to freescout to solve this.

I don't know if this directly answers the question I do think if SOGo was in the state it was now when we started, we probably would have used that from the get-go.
