Found the same with Zoho, and it's free. Used it because I didn't really care about the account and expected some shitty roundcube thing, but have been blown away. The app, website, and spam filtering absolutely crush what Gmail is offering.

For what it's worth, I self host a few e-mail servers and modern Roundcube is actually a pleasant experience, even if I like connecting Thunderbird directly.

Here's the mail server I like: https://github.com/docker-mailserver/docker-mailserver

I still very much rely on some cloud vendor e-mails for uptime and deliverability, though. Otherwise, with random VPSes you risk the IPs having bad reputation or having a plethora of issues (such as some providers not allowing e-mail ports).

I agree with you on the UI, but left Fastmail and went back to Google workspace because of Fastmails poor spam filtering. 1-2 pieces of spam were hitting my inbox daily. On Workspace it's 1-2 a month.
