I've been a fastmail customer for quite awhile now, having previously run my own e-mail server for both privacy and customizability reasons. Fastmail has managed both of these well -- but what I wanted to highlight is how they handled my mangled attempt at moving accounts to another phone. I've had my current phone long enough that I'd forgotten entirely about app passwords being separate -- so when I moved to the new phone, and carried over the password, it was failing to log in. This is good and normal, but what Fastmail did was above and beyond:
Their security advisory e-mail not only told me exactly what the problem was I was having, but also how to fix it.
Typically these e-mails are vague, just saying "login attempt detected, if it was you ignore it" and stopping there. Taking the effort to make this e-mail _useful_ and _problem solving_ is unusual and superior.
Highly recommend Fastmail.

Very happy across the board
I’ve been a customer for many years and I’ve been happy with the service, but it’s only recently that I had to lean on them for customer support, which is the ultimate test to see how customer-friendly they are. And I must say the response was fast and helpful. So I can happily recommend Fastmail to anyone who wants a private email account with some very interesting features like aliases.

With fastmail since 2006
I have had an account with fastmail since 2006. I stuck with them through the Opera debacle, the buying out of Opera by the fastmail team, the change of interface debacle, the changing to subscriptions and losing lifetime membership debacle. I did this because the fastmail ethos was all about being (and i quote), 'the fastest email on the planet', being completely secure and having no spam. I liked the plain interface and I have recommended it to countless others.
However I have had four months of them just changing the display of my email account, without choice or notice. I opened my email on no particular day and suddenly it was different colours and there are gmail style buttons next to all my addresses. The amount of fuss and ignorance in the customer service response was so time consuming and extremely stressful. I am not a techy, but I assume that if you change something in the interface, it is possible to change it back....The only thing they managed to change back was the colours, which i had to program myself using codes they sent me.
TODAY I have gone into my account and now when i open or go to compose a mail the window has shrunk!! I cant read the font. I can't resize it. All of these stupid and petty changes for no reason is an imposition, as the account I paid for in March (over $50) is not the same as the one I am now. This has completely upset my work flow and i find myself dreading opening my email now as it might have changed overnight again.
I would not recommend fastmail to anyone now and do not know what to do as my email address has been used by so many of my contacts for such a long time.
I am so sad that things have gone this way and fastmail does not care what its loyal customers think.
Response from Fastmail· Nov 26, 2025
Thank you for taking the time to share your feedback with us. We appreciate you for trusting us with your email for so many years, and we're sorry to hear that the recent changes have been frustrating.
We're always working to balance improvements with maintaining the features our users value most.
Regarding the font size issue you mentioned—while this isn't something we changed on our end, we are happy to work with you to troubleshoot. It sounds like your browser zoom may have been accidentally adjusted. You can usually reset this by pressing Cmd and 0 (Ctrl and 0 for Windows and Linux) while you're viewing Fastmail in your browser, and this should reset the zoom, restoring your text to its normal size. You can also adjust your Fastmail account's font settings to customize the size to your preference—there are six options for font size.
If you need further help with this or anything else, please don't hesitate to reach out to our support team directly. We're here to make sure your experience is as smooth as possible.

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.

In December the price will go up a lot
In December the price will go up by nearly 40%. I really like Fastmail, even though their support is slow to respond. The "we haven't raised out prices since..." excuse does not cut it. Now, I have to move all my emails to a more affordable service, which Fastmail does not make easy.
Response to reply -
The increase is not $1 a month, it is $3 a month. I have already left. You can judge the quality of the service from the time it took them to respond to this review, 6 weeks.
Response from Fastmail· Nov 27, 2025
Thank you for sharing your feedback. We really value hearing from you, and your experience with us is important to us.
The difference between the current pricing and the older pricing (from around 2017 for most users) is about $1 per month. If you are currently subscribed to certain older plans, you may see a greater increase, as these plans have gone even longer without a price increase. If this is the case, we've included a discount for your next renewal, which can be applied to any subscription duration, including our 3-year subscription.
We understand that price changes can be challenging, and we want to assure you that these decisions aren't made lightly. This update helps us continue providing a reliable email service without relying on advertising to you or selling your data. It also supports our contributions to open standards and the development of new features.
We aim to reply to urgent tickets within an hour, and we generally respond to all tickets within a few hours. If this isn't what you have experienced, please let us know at [email protected] so we can look into what happened!
We strongly believe that your data belongs to you. Your mail, calendars, and contacts are stored in open formats and can be downloaded or backed up using any number of standard tools. We provide a guide to download all of your data: https://www.fastmail.help/hc/en-us/articles/360060590573-Download-all-your-data. Should you ultimately decide to switch to another provider, and would like assistance with migrating, our support team is happy to help.
We hope you'll stay with us, but whatever you decide, we want to make sure you have a positive experience. We're grateful for the time you've been with Fastmail.

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.
