WHAT THEY COMPLAIN ABOUT · SHARE OF BAD REVIEWS
Bugs, things not working22%

17 of the 1 and 2 star reviews.

★★★★★ About 6-9 months (or longer) ago a very serious bug showed up and I reported it.
★★★★★ I thought this was my answer to my failing apple Mail app. After 3 months of use Spark is now acting as though its a fresh install and has deleated all saved mail!
★★★★★ It has lacked some integration feature for a while - like it doesn't integrate with the iOS calendar to add events to the calendar like the regular mail app does and now the Print / Save as PDF function is not working.
Worse after an update17%

13 of the 1 and 2 star reviews.

★★★★★ Since Readdle will not update Spark Classic to use the new Microsoft AuthN method, this has forced me to finally migrate to Apple's native Mail client.
★★★★★ It crushes the operating speed of the computer, is impossible to uninstall, constantly logs you out, and requests that you update the software before using it at least twice a week.
★★★★★ I've loved using spark for years no, but I recently updated Spark and have been having so many issues!
Login and account problems15%

12 of the 1 and 2 star reviews.

★★★★★ If you have an a Microsoft account, you get a non-dismissible notification that freezes your whole window forcing you to either remove your Microsoft or download their other forced-AI-in-everything app that's geared…
★★★★★ Use land line phones or email for your tw0-stage verification.
★★★★★ Out of nowhere it logged me out and when I try to log in it will show me like it is logging in but it just keep loading for hours.
Lost data, sync, backup15%

12 of the 1 and 2 star reviews.

★★★★★ Weeks have gone by and still no fix!
★★★★★ But over the past 2 weeks, it has randomly deleted sent emails.
★★★★★ Today I opened my Spark email app and all my emails are gone.
Crashes and freezes13%

10 of the 1 and 2 star reviews.

★★★★★ If you have an a Microsoft account, you get a non-dismissible notification that freezes your whole window forcing you to either remove your Microsoft or download their other forced-AI-in-everything app that's geared…
★★★★★ The app frequently crashes when searching for things.
★★★★★ It would go all the way through the login and authentication process and then the popup browser window would just close or crash.
No customer support12%

9 of the 1 and 2 star reviews.

★★★★★ So after months of the issue being unresolved, I tried contacting them again and YET AGAIN was told by someone on their Support Team that they are aware of the bug, but there is no ETA for it to be repaired.
★★★★★ I've tried to be in contact with support services but they are extremley slow and unresponsive.
★★★★★ I submitted a support ticket, and they asked me if I made the error.
Missing features8%

6 of the 1 and 2 star reviews.

★★★★★ I had to re-read every word, looking for what was removed, and re-entering the missing words.
★★★★★ It has lacked some integration feature for a while - like it doesn't integrate with the iOS calendar to add events to the calendar like the regular mail app does and now the Print / Save as PDF function is not…
★★★★★ Imagine that…an Emall Client that lacks the ability to Attach or Download Attachments.
Price and subscription6%

5 of the 1 and 2 star reviews.

★★★★★ All the normal, basic features you get with literally every other email service is locked behind a paywall.
★★★★★ The UI is inoffensive and minimal (as it's supposed to be), there is never a single ad or a subscription prompt, and it works perfectly.
★★★★★ I wrote to the Developers of course (over 5 months ago) and got the response that they are aware of the bug which, strangely enough, doesn't occcur in their new AI-Powered SUBSCRIPTION version.
WHAT THEY ASK FOR
  • Getting it updated took way longer than it should have, but at least Readdle listened to their users and changed course instead of forcing users on to the new (and far inferior) Spark Desktop app. 5★, Sep 29, 2026
  • As of October 2026, Microsoft is changing how their accounts work (according to Spark customer service) which should allow us to use the better “classic” app again. 5★, Sep 29, 2026
  • The calendar bit is not my favorite—I wish it would just defer to ical. 5★, Apr 3, 2026
  • Just wish it had an away message option. 4★, Jan 23, 2026
  • Not everyone needs AI mucking about everything - just plain old email thank you! 5★, Dec 24, 2025
  • There are a few things that I wish that it offered but "If it ain't broke, don't fix it!". 5★, Nov 19, 2025
  • Today after installing new update of Spark, every time i tried to open spark crashes right away on MacOS High Sierra 10.13.6 Please give last version before this update. 4★, Jun 22, 2025
  • Request: It would be great If you can make spark e-Mail Menubar acccessable like Airmai, amphedemin, battery etc. 4★, Jun 22, 2025

Easy to use21%

83 of the 4 and 5 star reviews.

★★★★★ The UI is clean and intuitive, there are useful customization options, the main things you want to do in an email app are right at your fingertips, and the things you only do occasionally are easy to find.
★★★★★ Finally, a fast, easy to use, no-nonsense mail app.
★★★★★ I've been using Stripe on my Mac Airlock Laptop, as well as my iPad, and my phone, and across all 3 devices it is so easy to use.
Looks great14%

56 of the 4 and 5 star reviews.

★★★★★ The UI is clean and intuitive, there are useful customization options, the main things you want to do in an email app are right at your fingertips, and the things you only do occasionally are easy to find.
★★★★★ Nice aesthetic, much prettier and easier to organize than the plain old gmail interface.
★★★★★ I stuck through with them because the interface and functionality was great.
Useful, it helps9%

36 of the 4 and 5 star reviews.

★★★★★ The UI is clean and intuitive, there are useful customization options, the main things you want to do in an email app are right at your fingertips, and the things you only do occasionally are easy to find.
★★★★★ I get my emails as they come in and it helps to keep my business emails separated from my personal emails.
★★★★★ I have been using Spark for several years now and find it so useful.
Worth the money8%

30 of the 4 and 5 star reviews.

★★★★★ I'm not asking for the app to be free, and I understand that subscriptions are useful for continuous development, but the reality is that I'm just not willing to pay monthly for an email client.
★★★★★ Great app that's worked well for these past 5 years. If I had any complaints, maybe it's that the emails sometimes disappear from the feed view and you have to search specifically for things. Or also that it sometimes…
★★★★★ For a free app, it's hard to beat.
Great support7%

28 of the 4 and 5 star reviews.

★★★★★ Changing my review back to 5 stars now that Readdle has updated Spark to support the new Microsoft account!
★★★★★ As of October 2026, Microsoft is changing how their accounts work (according to Spark customer service) which should allow us to use the better “classic” app again.
★★★★★ My hat is off to the great development and support teams at Readdle.

I JUST WANT TO SORT OLDEST TO NEWEST

If you can figure out how to utilize AI, surely you can figure out how to implement bilateral inbox sorting

★★★★★Oct 14, 2026
Stop working on Mac -

Now generates ‘firewall’ issues which it never used to have and no other apps on my computer generate. Just doesn’t work anymore at all.

★★★★★Oct 6, 2026
Almost Daily Email accounts are logged out

Almost every day the logged in accounts get logged out.

★★★★★Sep 29, 2026
Spark Classic no longer works with Microsoft accounts

*Update 9/29/2026* Changing my review back to 5 stars now that Readdle has updated Spark to support the new Microsoft account! Getting it updated took way longer than it should have, but at least Readdle listened to their users and changed course instead of forcing users on to the new (and far inferior) Spark Desktop app. So thank you!

★★★★★Sep 29, 2026
So much better than the “updated” version

The “classic” app was the best mail app out there, but stopped working with Microsoft accounts, so I was forced to “upgrade” to the newer Desktop-AI version. The newer one is terrible - unintuitive, overblown, clunky and hard to use. As of October 2026, Microsoft is changing how their accounts work (according to Spark customer service) which should allow us to use the better “classic” app again. So thankful!

★★★★★Sep 22, 2026
Stoped working with Outlook

They stoped supporting outlook to force users on to the new horrible version.
