  • 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!
  • 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!

    They stoped supporting outlook to force users on to the new horrible version.
  • Bad faith advertising

    Spark has a history of adding advertising to this app to encourage users to not use Spark Classic and use their new desktop app. That is fine, but you cannot get rid of the message. They just added one now for “AI agents” in the lower left hand corner. I cannot get rid of it. They need to stop doing this.
  • Sick of it

    I have kept Spark Classic because I absolutely do not want AI. Yet I’m constantly hassled via notifications inside the app and via email to try the AI garbage. How many times do I have to say no? If I choose the non-AI version of the app, why am I being hassled about AI features? I won’t be using it at all anymore.

  • Deal breaker bug

    I have used Spark for years as my go-to app for email management, both on Mac and iPhone. About 6-9 months (or longer) ago a very serious bug showed up and I reported it. I endured through the pain of this bug hoping for a fix that never came. I then reported it again. They acknowledged it and that they were working on it. Weeks have gone by and still no fix! What is the bug, you ask? While composing or responding to an email, I use voice annotation (Siri) all the time to type for me. Siri works fine in hearing what I speak and putting the words down in Spark. But then Spark decides to randomly delete key words through out the message that Siri had dictated. It made the message un-sendable! Important words randomly removed here and there. I had to re-read every word, looking for what was removed, and re-entering the missing words. I figured this was their AI trying to be “helpful”. But in Settings there is a way to disable AI completely. It didn’t work. This very annoying bug still exhibited itself. I’ve had it with Spark! I’m sorry our relationship has to end but I can’t live with that time consuming bug that annoys me very much.
  • Don’t want your stupid AI

    This app was wonderful, then it decided to jam AI down your throat, and it became loathsome.
  • Finally, a reason to move to the MacOS native Mail app

    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. Spark Desktop has kludgy UX and is a resource hog which makes the migration to that app a non-starter. I’ve tried using 2 mail apps, but that just sucks so I’m moving everything to Mac Mail.
