  1. [R2] Spark Mail 5/5 · GB Very reliable.: I have used Spark for years, it is an ideal app to have numerous different email addresses on. I use it on all my iOS and MacBook devices. I wouldn’t hesitate to recommend.
  2. [R13] Spark Mail 1/5 · GB 1 year limit on AI features, even on Plus subscription.: Pretty amusing considering Google Gemini offers this for free. And that you have no advantage in terms of data privacy when looking at your terms and conditions and privacy policy.
  3. [R17] Spark Mail 5/5 · GB Amazing App: Spark is the best email app. I love various features, the lovely design and their way of doing things.
  4. [R18] Spark Mail 3/5 · GB Great app: I enjoy using the app and find the layout and focus better than standard mail app. BUT Using a keyword results vary depending on the viewing mode, in some cases in focused list i just get no results and have to change to classic view. I think search should return results regardless. I find i don’t really use the ai and TBH it’s probably not worth it unless you pay the full premium
  5. [R7] Spark Mail 2/5 · GB Could do with a tutorial: I’m sure there are benefits I’m not understanding how to use to full advantage. Only had it a few weeks will keep trying to opt for it over my usual system but it did transfer mail over easily.
  6. [R9] Spark Mail 3/5 · GB Not intuitive: I’ve tried this app briefly. Although it clearly has a different approach to email, I didn’t find the interface intuitive. Perhaps it’s because it’s doing things for me and I can’t see what it’s doing. I’m worried that it’s doing stuff that I don’t want. I don’t think I’ll keep using it, as I’m finding it hard to see what’s what.
  7. [R28] Spark Mail 1/5 · GB Used to be great.: Update- after many years, I have ditched Spark. The AI nonsense is becoming so annoying, and the cost is outrageous. … This is probably still my favourite iPhone email app, I’ve used it for many years. But the new UI is a serious step in the wrong direction. I find it busy, messy and confusing. It’s also a bit of an inefficient use of screen space too. Please bring back the o
  8. [R1] Spark Mail 1/5 · GB Used to be good but latest update doesn’t work: Just had an update of spark and now can’t log in to my bt email. I keep being told the email server is incorrect despite the fact I got the details directly from BT and these same details work on another email app without issue. Please fix this problem as I used to enjoy Spark
  9. [R3] Spark Mail 3/5 · GB Good app but scrolling bug is making me consider switching: I’ve been using spark for years and have enjoyed it but recently a bug has been introduced which means longer emails get frozen at the top and you can’t scroll don’t. It’s really annoying as the only workaround is to go to another message then return to the email you were originally trying to read
  10. [R4] Spark Mail 2/5 · GB Was great: Sadly I have to stop using Spark. I have used it for some time now and it has been easily the best email client for iOS. However it now randomly stops sending emails and they just get stuck in the outbox. Without checking I don’t know if they’ve sent or not. It is no longer reliable enough for my needs, so the search for an email app starts again.
  11. [R21] Spark Mail 3/5 · GB Subscription model kills this dead for me: It’s all in the title
  12. [R16] Spark Mail 1/5 · GB Calendar sync doesn’t work: The mail app is very good, packed with lots of useful features. I’ve finally found a mail app which is a good replacement for Mac mail. The only downside is the calendar support doesn’t work and is problematic, I’ve had to switch it off due to various issues with it. I’ve dealing with support for the last couple of years and they acknowledge calendar sync is an issue, b
  13. [R19] Spark Mail 1/5 · GB Misses folders. Support never respond.: Lots of Microsoft (outlook) subfolders disappear. They give some fixes via a bot that invariably stop emails working even more. Support responded to one email with some generic answers like turn it off and on again, then ignored the following 4 emails where I asked for a bit more help. Never got it working. Shame about the service. Sure it would have
  14. [R34] Spark Mail 5/5 · GB Best so far: It’s still the best app I’ve used. By the way, I am using the free version!
  15. [R39] Spark Mail 4/5 · GB Free version is great: Been using the free version for over a month now, trying to navigate away from Google. It’s great. It’s a shame that so many security/blocking bots are premium but I’m not looking for another subscription right now. The free app works just fine for me and I can see/edit our family Google calendar which is great
  16. [R41] Spark Mail 4/5 · GB Deceptive: Thought it was free as some of the reviews say. FREE for basic functionality but a HIGH subscription fee for a lot of features that are not practical for a sole user.
  17. [R10] Spark Mail 2/5 · GB Patchy search or AI slop search. Your choice: The UI is great but functionally if you have a large inbox, the standard search returns only patchy results even with simple queries which is really annoying if you’re looking for a specific email. The AI search randomly hallucinates and provides questionable results so you can’t really trust that either. Used it for almost a year, binning it off to
  18. [R48] Spark Mail 5/5 · GB Unbelievable AI: I think the AI on this is the best AI… especially when summarising a whole Email chain and using transcripts with Teams 👌
