Why I’m not using Fastmail

Prepare for a somewhat ranty post, but it doesn’t come from a bad place. I honestly want Fastmail to succeed. I’m eager to see more alternatives for email hosting, and clients (and there are scaringly few).
I also acknowledge that some of the problems I bumped into are quite specific to my own setup, which isn’t common. So in some ways, it’s not about you, Fastmail. It’s me. Make your own judgement.

TL;DR – Fastmail is pretty neat, but their support sucks. Their support ticket system sucks even more, and their product is not clear enough to work without support. From my personal experience anyway.


I’ve been reading lots of positive comments about Fastmail on HackerNews. Including a couple of posts listing people’s experience switching to Fastmail from Gmail.

I am half-hosting my own email domain, but primarily use Gmail. My setup is definitely odd, but it works. My domain MX record points to my own server, where I run a cocktail of postfix/spamassassin/postgrey/dovecot/milters/etc. Email gets stored and is accessible via POP3/IMAP as well as via Roundcube webmail. But I also forward my email to a sub-domain hosted on Google. And so I tend to read and write emails mostly using Gmail. I was lucky to join at a time when it was free for a domain with up to 50 accounts. So I pay nothing, and get quite a lot. But with all the privacy implications and reliance on Google, I was wondering if I could move to Fastmail.

My primary requirements were: Storage and Interface.

Storage, because I don’t want to store Gigs of emails on my own, set up extensive backups and so on (I currently auto-archive old emails into tar files, so I can restore them, but they’re not searchable or easily accessible on a day-to-day basis). Interface, because Roundcube isn’t nearly a match to Gmail, and I’m not aware of any decent mobile email client for iPhone (I enjoyed K-9 on Android though). Fastmail fulfilled both of these pretty well. Their storage was ample (25 Gigs for $50/year). Their UI was pretty neat and fast. Their iPhone client was good-enough for me as well.

First round of problems

I started-off by setting up my domain on Fastmail, the way I imagined would be best. I defined my top-level domain and set an alias with the sub-domain to forward emails to. There was a setting to “Route all email internally” on the top domain. So I thought this should work as expected. It didn’t. I was getting strange bounces from Fastmail. That’s where I decided to contact their support for the first time.

I’ve read in a couple of places that the Fastmail support is great. This is something you don’t get with Gmail and is worth paying for. My experience was totally different.

The first response suggested I upgrade to the paid plan, even though it was still during the trial period. I didn’t mind that much, because I truly believed I would use the service for long. So I upgraded. But the problem didn’t go away.

First impressions

At this point, I already bumped into two shortcomings of the Fastmail support:

  • The support ticket system was horrific. It was like going back to 1999. You can’t reply to support tickets via email. The interface is ugly. It’s hard to differentiate between my messages and the answers. It was a real turn-off after being quite impressed with the email client interface. I think I couldn’t even attach more than one file…
  • It took quite a bit of time to get answers. Ok, I wasn’t expecting an instant response, but because my case required several back-and-forth, it really took too long to wait a few hours between each interaction. Every mistake or misunderstanding in one of the interactions just makes the whole process longer still.

So with these constraints, it took a few days to get things working. I didn’t give up on Fastmail at this point, but was unimpressed and slightly worried what might happen if there was a real problem …

Second round of problems

So my email and domains were all routed correctly at this point. Sweet. Next step: import my email from Gmail. I had around 11Gb of emails on Gmail, so I knew this will take some time. Nevertheless, I was encouraged to see that Gmail was explicitly mentioned, and that they had an option to avoid duplicates. I knew that a naive IMAP import might have trouble with multiple labels on Gmail. And surely this wasn’t the first migration FastMail had to do. I therefore kicked-off the process to migrate everything into a separate folder, and avoid duplicates. I had full faith that FastMail will take care of everything the Right Way. Wouldn’t you??

After a few days of the migration running, I noticed that my email usage was climbing up way above 11Gb. At this point I suspected something wasn’t working properly. I promptly contacted the Fastmail support and asked about the discrepancy with the storage space. That’s where the 3rd shortcoming of Fastmail emerged (and that was the last straw):

  • First level support is incredibly incompetent. I was getting copy&paste replies and it was quite obvious they didn’t read my questions. They did not understand the problem at all. The best I could hope for is being bumped-up to 2nd level support, which was better.

It took several times to explain to the support staff that sending back a copy&paste reply does not actually answer any of my questions. I was then later given wrong instructions about the option to choose in order to purge duplicate messages, but even after finding it by myself, the system was returning 500s every time I tried it. I forwarded the error message with all necessary details, but the responses I was getting were along the lines of “you’re doing something wrong”. I’m sorry, but no system should 500 if I do something wrong. Not a solid system, anyway. It looked like the system wasn’t able to process duplicate flagging or deletion when the folder size was in the region of 25Gb, or perhaps that since at this point, my Inbox was over the size limit, strange things started to happen. I don’t know.

At this point, I was stuck with a 100% full mailbox, which stopped accepting emails, and support staff that weren’t being helpful at all. To make matters worse, the migration process wasn’t giving any progress indication whatsoever. You get notified via email when it finishes. That’s it. There’s no way to pause it. No way to see how many Gbs or estimated time left. Nothing.

I did eventually figure out my “own” workaround to delete duplicates. I simply had to select a smaller sub-folder, and purge duplicates there, instead of the “master” folder. But at that point, I decided it’s not worth it. The support staff wasn’t even clever enough to tell me to do that. Not quite what I’d expect from the same people who created JMAP – a faster and better alternative to IMAP.

Parting thoughts

I really enjoyed the Fastmail interface, and was happy to pay for the service that gives ample storage. I truly want to support services that compete with Gmail’s dominance. Even in a small way. From reading HackerNews, I have a lot of respect for FastMail’s developers and they’re doing lots of things well. It just didn’t feel as refined or as solid as I was expecting it, and their support did not give me much confidence at all.

I know that if something went wrong with my Gmail account, nobody would even bother replying to my email. Google doesn’t need me even if I was paying them. Let alone when I don’t. Unfortunately however, I still somehow feel more safe with Google than switching to FastMail.

In the interest of transparency, here’s the two conversations I had with Fastmail support (copied from their support system and converted to PDF). ticket #1 and ticket #2… Note that the conversation is in reverse chronological order, as they appear on the FastMail support system.

EDIT: 2017

A year later, Fastmail charged me for a renewal fee, even though the subscription was cancelled and refunded…I’ve contacted their support to request a refund.

I can totally relate to your experiences with their support.

Around December 2016 I created a free testaccount. Now (Feb 2017) I wanted to convert this to their basic plan. After paying 5$ for the first month of subscription that would start today (so I thought) I got a message that explained to me that my subscription expired last month. Okay?
I contacted support and they answered: ‘…when you renew your account, the next subscription starts from the *end* of the previous subscription’. This means I just payed 5$ for nothing, that’s absolutely weird!
According to them – If I would decide to go on a payed plan in June – I would have to pay for half a year of service that I could never have used. This is called fraud.

I have had a paid for fastmail account for many years with no problems. However they recently blocked my account because it had been compromised. Unblocking the account should have been easy, using the ticket system. Unfortunately after two weeks they have simply not responded to four requests. It is impossible to contact them in any other way. So I am actually paying for a service they are not providing. Avoid fastmail!

I have had a free fastmail account for many years with no problems.
Recently they notified me that Free accounts will be discontinued. As I was using Fastmail as my main messaging account I decided to accept discounted offer and pay for 12 months.
They recently blocked my account because someone has been bouncing his undelivered spam messages to my account. Unblocking the account should have been easy, using the ticket system. No such luck.
Their support is incredibly incompetent. I was getting copy&paste replies and it was quite obvious they didn’t read my questions or my messages. Their reply is do ‘this’ and ‘that’. After complying… same problem persisted and my account was blocked again.
I could only contact them through their support ticket system which sucks even more than poor support they provide.

They did not seem to understand the problem at all.
My account is blocked again because of a same problem and I am actually paying for a service they are not providing.
Fastmail is not for me.
Pity, as I had many years of trouble free service from them… BUT when things go wrong… they do not seem to understand what is the actual problem.

Fastmail sent me a message to say I will no longer receive mail and must clear some mail to make room, or upgrade from free to pay. I have made room, but not going to pay more for room i don’t need. I still do not receive mail, some of which is urgent, until i upgrade. So my mail is being held to ransom?

I’ve been a Fastmail customer myself for several years. It’s my main email provider.

First of all there ticket system has been changed recently. You can reply to a support ticket by my email now.

Secondly, so far I’ve opened like eight or ten tickets with them over the past couple of years. All of them have been answered in a timely and professional manner. Maybe I’m an exception. I don’t know. But this is my experience with them. Just today I had a question about plus addressing (youremail+folder_name@fastmail will sort emails into folders automatically) and they replied within 30 minutes after I had opened the ticket with them.

One time some emails were not delivered into my inbox for some unknown reason. I suspected some technical glitch. I opened a ticket and support gave me detailed instructions to sort some test emails into a special folder accessible for support staff. They even analyzed log files and sent me excerpts from them to show me what was going on. Eventually the problem solved itself and the underlying reason was not found. But it showed me that Fastmail support indeed was taking my issue somewhat seriously.

In my personal opinion their WebUI is the best I’ve ever seen with any email service. I’ve referred some people to Fastmail and all of them told me that they are more than happy with Fastmail’s service and especially like the WebUI. But I’m not aware whether or not they have ever opened a support ticket with Fastmail.

Lastly, I like the honesty of Fastmail. I once had an email provider who openly stated that they would not admit having technical difficulties because people could get the impression they would be unreliable. Fastmail on the other hand is absolutely open about technical problems. They even have their own status page at

Thanks Seb,

I’m really happy to hear that things are improving. I think I mentioned that I want Fastmail to succeed, and I really do. There’s lots to like about Fastmail.

Unfortunately I bumped into several issues, not just with the support interface, but also response times and using canned responses without actually reading what I wrote. Perhaps this improved as well, and that’s great. I certainly hope it did.

Maybe I’ll give them another chance one day. My personal experience however was pretty disappointing, and I’m a bit hesitant to go through the whole process again …


I’ve had enough of Fastmail, which is a great disappointment having been with them since at least 2004. They have slowly, but surely gone downhill, from an efficient, effective email provider that was way above the competition, to one that is confusing and unreliable. Since they have ceased the Classic interface, some of my email has just disappeared. The excuses as to why they had to do this don’t hold water and I am only remaining with them while I look for which service to move to. Not worth paying for and frankly too problematic even if free.

Fastmail was my favourite email service, until some smart ass pushed up the pricing on all types of accounts. Used to spend 20 dollars a year and suddenly they raised up to 30 dollars. They knocked out the lite and most cheap account so we are left with the minimum 30 USD/year to start off. Unfortunately, there is no other alternative to Fastmail and that creates the “we-do-what-ever-we-want-because-we-don’t-have-competition”. Basic economic rules… Sad Face.

The search box and the ability to ‘select all’ are two funtions that made fastmail stand out above the ipad’s ios email client. However, since a recent ‘upgrade’, I can’t find these functions. I am sure they must still exist, and I have gone to some trouble looking, but I can’t find them anywhere. It’s so frustrating when important changes like this are made — often with no apparent benefit to users. I resent having to watch instructional youtubes to catch up with new layout etc just because some web designer thought it was time for a change.

I just opened a fastmail account. I now have a seriously important letter to send & I’m not allowed to – because it’s now permanently stuck in my ‘draughts’ folder. These guys are shit. DO NOT USE THEM !!

Apparently people come here when they are frustrated about Fastmail. I’m not, using it for almost 5 years and while I still run my own IMAP server for private Email I can only say positive things about Fastmail for my business. Super reliable service, good support, great security. Web interface is ok but I definitely love CalDAV & CardDAV sync. Would not change anymore.

Fastmail is offering a 30-day free trial without a credit card, but does require a phone. I signed up yesterday, they got my cell number.

I then worked until about 1:30 am, selectively sending individual inquiries to about 8 or 9 professional researchers, looking to hire someone. The inquiries had the name, address, phone & fax of each of the researchers. This was obviously not “spam”.

Today, I tried to login to check for replies and found my account GONE. Fastmail screwed me, even with my cell phone; they screwed me with these people that I wrote to. They screwed me on this emergency project; and their “support” ticket alleges it’ll be another 24-48 hours before they get back to me. The delay is fatal to my research work.

Fastmail has my cell, but did NOT even have the courtesy to send me a TEXT to even offer me the chance to reconfirm my account. They just DESTROYED it.

Uncivilized thugs online, we can do with less of them!

Therefore, if you are tempted to sign up for the FAKE 30-day “free trial” at Fastmail, be advised that you risk being arbitrarily and seriously SCREWED.

just subscribe for yearly plan, suddenly can’t email, they don’t send any notification / alert at all.
