I love Fastmail. Fast, easy, flexible. I might be a power user, but they have everything I need and the price is totally affordable.

Excellent customer service
I have been with this company for many years. Because of my own negligence, I failed to instate two step verification, in spite of many nudgings from the company, i was hacked and lost access to the account temporarily.
Customer service were quick, efficient and helpful in getting me back up and running. I was very impressed.

Fastmail is the best mail provider…
Fastmail is the best mail provider currently on the market. I think it is fair to say this roughly without qualification.
While other companies are doing shiny bullshit, Fastmail has been prioritizing basic usability and having things work properly for several decades, and I think it shows. With Gmail or ProtonMail, there is no end of issues with integrating them with third party tools, but on Fastmail, you are going to be able to use any email client you want, and any external integration you want, and if anything doesn't work, it is going to be the fault of the external tool, and there is going to be documentation you can point to for explaining why. This is because Fastmail actually cares about following open standards for their services and APIs, and in fact they've even done extensive work with the internet standards working groups to develop new public standards to improve email for everyone - rather than just implementing some proprietary thing that will only work for your own service and doesn't integrate with anything else.
There is no AI slop, there is no advertising, there is no constant stream of terms-of-service "pray we do not alter it further" updates, there are no random popups everywhere nagging you to use whatever feature is going to get some middle manager a promotion - it's just email, calendar, contacts - and it works. Reliably, and with thorough support for a variety of use cases.
I want to briefly highlight some common criticisms of Fastmail that I see. One is the spam filtering ostensibly not being as "good" as Google's. Well, it depends how you measure it. Back when I used Gmail, there would still be false positives and false negatives. But the reason Google's spam filter is so "effective" is because they are actively abusing their monopoly position to deny anyone from being able to deliver mail to Gmail users unless Google likes them. You can't do that kind of thing in an ethical way. Fastmail's spam filter is perfectly well good enough, and I would encourage people to think about how much time they *actually* spend clicking the "mark as spam" a couple extra times a month, compared with how many times they have to click the "no, I don't want to open this in goddamn Gemini" button and similar obstructions in Gmail.
Another thing I've seen people complain about is "it's not end-to-end encrypted", so "you should use ProtonMail instead". Okay, no. E2EE for email is complete security theater outside of a few specialized use cases. Even if you use ProtonMail, 99% of your mail is not going to be encrypted at rest or in transit anyway, because that only happens when you're mailing people who also use ProtonMail. And really, you're going to be hatching your criminal mastermind plots over *email*? No. What you want for email is a broad assurance that the people managing your data are going to steward it responsibly and defend you from bullshit that would lead to data leaks and moral turpitude. I trust Fastmail with that based on their track record and how they engineer. Frankly I trust ProtonMail less, because of the shiny "AI" stuff that's showing up - a red flag if I ever saw one. If you still aren't convinced, I would recommend checking the Fastmail blog, as they actually have written specifically about the technical challenges with E2EE email and why they've made the decision not to implement it - and I both think that those decisions are justified, and that it is a good sign when companies are willing to put their reasoning for things in public, in detail, outside of marketing copy.
Anyway, rant over about that. The product overall is great, the programmability is excellent - having full RFC-compliant Sieve for mail filtering, on top of the already-better-than-Gmail graphical interface for managing the filters - having a next-generation JMAP API for your own scripting - being able to use all the open-source tools like vdirsyncer etc to implement new features with relatively low lift - being able to email support and get a response from a person who talks like an actual human - I think it is very unlikely that I would need to find a new email host anytime soon.

Worth Every Penny!
I have used Fastmail for years now and absolutely love it and recommend it. Their customer service (on the rare occasions it is needed) is fast and thorough. I run a large ministry at my church, supervising one hundred leaders who shepherd nearly 900 women attending our Bible study. I am busy texting and emailing all day every day. Fastmail's excellent capacity for creating files to store emails, and the advanced search capabilities make it possible for me to keep track of the myriad of communications I send and receive daily. I recommend it to people constantly! My job is a volunteer position, I am not paid staff. But the cost of the paid version of Fastmail is worth EVERY penny!!

I use Fastmail for ages
I use Fastmail for ages, since they take over Operamail. Never ever had any issues so far. As a private person and old school user, I use paid pop3, so I download all my mails and have it on my hard drive. Whenever the Australia Government drives crazy, they can shut down my account without any loss. Some News from Down under sounds a bit weird.
May it is time to reduce my activities on the internet, due to all this ID crap, verification force, data collection nightmare. I'll stay with Fastmail as long as possible but will have a backup place and already have.

Super easy to switch from the clunky…
Super easy to switch from the clunky yahoo interface. Mostly automatic, except did have to export my yahoo contacts to a file, then upload to Fastmail.
Can send end and receive using my old yahoo address, so the transition is not so painful, and can be completed at my own pace.
Working inbox window is more roomy and not so cluttered as yahoo, and requires fewer swipes or clicks to see what you want.

Super supportive, Fastmail take customer privacy, security and support seriously
I have been with Fastmail since the very beginning and have always found them super helpful whenever I needed support. I have just created a new website and had to transfer a domain and then setup the custom email. I knew absolutely nothing when I started. Maya guided me through and I have just now finished the process successfully. Fastmail take customer privacy, security and support seriously and are great to work with. Highly recommend them.

You HAVE to get Fastmail!
Fastmail is everything gmail and yahoo is not. No advertising, fabulous spam protection and SUPPORT. The interface is far better than gmail. You get out of office or on vacation included. You can set up rules without having to pay extra. Did I mention support? Yes, you get real honest-to-goodness support. Any question, any time. Sometimes I'm stupid and the answer is obvious. Sometimes it's not so obvious, but there are tiers for support and you will always get an answer.
