Have used fastmail.com for 6 years (with a custom domain). No complaints. Web/mobile apps work fine. Would recommend.

++ to fastmail. Their spam filtering has been excellent and they have a good stance on privacy.

Sign up for a year and get it at a good price I think Google workspace offers slight discount.

At least that’s what I did

iCloud with custom domain. I only use Google for my company email domain and office.

3.25€ per month plus domain(5€/y): a small vserver with postfix, dovecot rspamd. Aliases come from postgres

I wouldn’t recommend rolling your own email server unless you’re just into the challenge (and even then, I wouldn’t put anything mission critical on it). There are hosted options that can offer similar flexibility for similar (or less) costs as that of a tiny VPS.

Not the person you are replying to but I keep email on a tiny VPS for a few domains mostly for things that are behind an email-wall. Not quite throw-away but I control the access, logs, limits, etc... I set up FCrDNS+SPF+DMARC but no DKIM on those. Nowadays if people create new VPS accounts they will have to open a ticket to get port 25 outbound opened up. It's a per account basis on many VPS providers now and requires agreeing to not abuse it or lose the account.

There are only three businesses that have ever blocked email from or to me and two of them were cellular service providers. They all appear to use the same anti-fraud service. [Edit: and Tractor Supply]. I use that when I want to email someone that I am certain will abuse my email address or domain or if I want to receive a massive file or set of files from someone. That keeps the noise off Fastmail which I also use, mostly for family and business related stuff. With Fastmail I pull the emails off the server as fast as I can using Thunderbird in the event they get popped by citizen or government attackers such as the AU government should they do mass surveillance some day. Fastmail is under AU jurisdiction. As a side note, Thunderbird makes PGP encrypting emails trivial.

Another nifty thing one can do on their own mail server is pin TLS certs of specific people or businesses to see if something has changed. Not everyone would need this but monitoring certs with bash+openssl is super easy. It's useful for fringe cases.

I’ve been using MXRoute, which is about as inexpensive as one could expect (~$40/year for a storage tier, unlimited domains and accounts up to that storage limit). It’s been rock solid reliable for the last few years, but it does require a bit of DNS knowledge to really setup properly.

Google Workspace, really considering moving, though sadly means I'll lose the Google account associated with it (and all the google services that belong to that Google account)

Protonmail for the last 4 years. They have come a long way. I’ve also bought into their ecosystem— vpn, mail, storage drive.

gmail for government / bank / "official" stuff that I can't loose

fastmail for a mailing list / sports team thing that I help run. local hockey league stuff. someone else set it up but it works fine and we keep using it.

protonmail for personal email, previously tutanota before that

FASTMAIL number one hands down

iCloud+ with custom domain. $0.99/month

Google workspace!
