1. [R87] 5/5 · US Best email client: Smart notifications and email organization are one of the things I like most
2. [R88] 5/5 · US Probably the best email app I’ve ever used: Literally the best Email app ever. Sorting through newsletters, notifications, and direct emails is fantastic, multiple email accounts work flawlessly, and notifications are perfect to manage. It would be nice if there wasn’t a paywall to block messages, but I get it.
3. [R89] 5/5 · US The answer to my email problems: This email client addresses problems with organization, prioritization, drafting emails that actually sound similar to you, and unlike most other solutions, gives you a chance to make a choice before it drafts a response. It also solves the Outlook problem of not being able to save directly to a OneDrive folder (as long as you have the OneDrive desktop app installe
4. [R93] 5/5 · US Spark Mail Review: Spark is doing much better (March 2026). I appreciate all the options for saving e-mails (PDF, Files, share, etc.). Also now with AI integrations. I love how Spark organizes my e-mails, which helps keep things neat.
5. [R16] 5/5 · US It just gets better: I’ve been using Spark several years now. I started with it because SPAM was out of control and Spark had a positive control over senders feature. Getting through all the senders was a slog but after that 100% control! Then they added AI for finding emails and whatnot. No more am I anxious I cannot find an email. I went from the most disorganized person to the one everyone reli
6. [R18] 4/5 · US Amazingly helpful: Being someone with executive functioning issues having Spark and especially the AI to help me has made life a little easier. I gave it 4 stars due the price for everything included. As someone waiting for a disability case to be approved it’s hard to afford and I will probably have to find something similar eventually.
7. [R67] 5/5 · US SALUTEM INITIUM^ Email: Ai adds too the Good of newsletters inbox reading and moving all mail summarize them. It’s a nice service. ImperiumProphetGoodfaith PeterMichaelMartinJr
8. [R84] 5/5 · US Emailing with Spark: Have never had any issue with Spark, modern and futuristic it gets any mail or multitasking done quickly even with older devices. Subscription is there for Spark AI but you don’t have to accept the ai if you just want to use the app for emails. Good luck!
9. [R43] 5/5 · US Hands down the best email client.: I’ve been using Spark for many years across many devices (iPhone, multiple iPads, multiple MacBooks, Mac mini, pc) and it is the most clean and well functioning client. I’ve used both the free and paid tiers and am currently back on free tier which is perfect for a regular person. All your mail is stored on sparks servers and syncs perfectly across devices. The l
10. [R47] 5/5 · US Finally! A Breath of Fresh Air: At last, an iPhone email client with all the options and goodies, easy to customize. And with SUPER customer and tech support. And not just the iPhone/Ios! Android & PC, too.
11. [R49] 5/5 · US The best email client for Mac and iOS: Even better than Superhuman and other more expensive alternatives, I've tried literally every email client that exists, or at least close to it, and Spark has the best balance of features. Only thing I wish is that when you clear your inbox and hit Inbox Zero, there was a classier screen that got displayed. Currently, it's kind of a tacky image and an ugly fo
12. [R61] 5/5 · US My favorite email app: Great app, great support, and all around my favorite email app.
13. [R31] 5/5 · US First rate: It’s a great email app, my favorite, and I’ve used many. I particularly like its ability to snooze emails.
14. [R1] 1/5 · US Locks up and gets stuck every day on brand new iPhone 17 pro max, daily.: I have been using Spark email solely for five years. Locks up and gets stuck every day on brand new iPhone 17 pro max, daily. It started screwing up on my iPhone 13 Pro, this year. It is not much better on my new 17 Pro Max.
15. [R3] 1/5 · US Was great, now useless: This app used to be an amazing email app now on an iPhone 13 running iOS 26.5 it is virtually unusable. I have uninstalled and reinstalled the app over a dozen times and it’s still only loads about 1/3 of the time. And when it does load it takes 10 times longer than any other app out there ** if you don’t have the absolute newest iPhone, and a ton of patience, you might as
16. [R6] 1/5 · US Sub par experience in the last few months: Not sure what happened, but recently that app has been buggy and I keep checking the App Store for updates. Currently, any email that I open has the Accept and Block button overlay gets stuck while scrolling the email, the only way to get out of it is to close the app and reopen. This is extremely frustrating and happens on a regular basis.
17. [R9] 1/5 · US More frequent bugs: Recently, I’ve been encountering a frequent bug my the iPhone 17 app. After opening an email, everything initially loads normally. However, after one or two seconds, the image at the top of the email becomes collapsed or partially hidden. At that point, the entire email becomes unresponsive and I can no longer scroll. The only workaround is to exit back to the email list and
18. [R2] 2/5 · US Missing core functionality: No way to view only unread messages. Feel like that’s a pretty major oversight. This is not something that should be put behind a paywall, that’s just sleazy.
19. [R13] 1/5 · US Great app: That is so easy I can’t go back the Apple mail because I forgot how it works haha. That was before I got a $100 bill to get mail. I just couldn’t justify spending this much on getting email when I could do the same for free. It may not be as streamlined as Spark but the final result is the same.
20. [R30] 3/5 · US Paywalled: For trying to set up a Smart Folder, when search folders are free in outlook? Nope. (I’d just use outlook for everything but would like to use a separate app for work and personal)
21. [R55] 1/5 · US This used to be my only mail client…: I finally took the plunge and deleted the app. Removed my account because I had enough. It was good when it started but it chipped away at everything it was known for behind a paywall. I’m good. I’ll move back to apple, which also sucks but for some reason, this disappointed me so much more. They asked what is behind a paywall. It’s BLOCK. Something so basic i
22. [R4] 4/5 · US Mostly good, could be better: Mostly good but does not do a good job of search. It frequently leaves out older emails and the sort order it presents emails in is unintuitive. I often resort to the default Mail app when I need to search for an email.
23. [R10] 2/5 · US Unreliable: I have been using spark for years. Over the past several months the app has become very unreliable. Emails won’t load, sometimes can’t scroll down on an email, it will show a notification but everything is read, and other similar issues. It feels like they started adding AI bloat and the reliability suffered. Finally giving up and letting my renewal lapse.
24. [R11] 2/5 · US Too slow now! 👎: No pop mail option. Last little while retrieving and sending mail has been an issue where it's become increasingly too slow to use. This is new issue. I have maybe 10 plus accounts. Maybe Spark AI is scraping my emails in the background but Spark has become too slow and unreliable to continue to use.
25. [R5] 2/5 · US Long time user: At this point, this is no longer an email app. It is so bloated with AI slop that I can barely read an email anymore. I will be looking for alternatives, disappointing as I really love supporting this team. But I guess priorities are now on AI and not helping me read and reply to emails.
26. [R15] 1/5 · US Too many AI features: Have been using Spark for many years and with all the new half-finished additional features that have been implemented the app became unusable and made me look elsewhere. The idea is good and it was the best email app available, but since they added all the features not needed in an email app like calendar and AI that does only partially work, the app became unusable. Also se
27. [R23] 1/5 · US Not good: Too many “ai” features make it hard to use
28. [R40] 2/5 · US Not What It Used To Be: Used to love Spark Mail. It was so reliable and easy to navigate. Suddenly am not receiving g email notifications or actual emails themselves. Tries everything known to man to fix the problem but nothing worked. Sometimes keeping things simple is better. Keep focused on functionality rather than overloading the app with too many AI features and other unnecessary things. You
29. [R57] 1/5 · US Not loading: Been using Spark for years and loved it up until 2 months ago…for some reason I’m not getting my notifications I actually have to open the app to get the new emails and I don’t like that.
30. [R59] 4/5 · US Email notification triggers and others: Great job folks! Notification trigger issues resolved on phone and watch. Email delivery latency issues, resolved. Cross device sync issues, resolved. Well done folks, keep those builds coming. Okay, so now notification triggers don’t work on my iPhone, iPad, and watch. They used to, with the same build, but have mysteriously vanished. Perhaps you should
31. [R76] 3/5 · US Notifications not working: I used this app for a long period of time but out of nowhere, I stopped receiving notifications even though I had them enabled in my settings and made sure everything was properly turned on through the app. I ended up switching to Canary instead and haven’t had those issues. I’d like to give this app a second chance but I’m worried I’ll miss important emails. Outside of
32. [R27] 1/5 · US Translation features removed to force paid AI upgrades. Infuriating!: Why is the iOS text selection pop-up menu in Spark so incredibly limited compared to other apps? Essential pop up features like “Translate”and “Search Web” are completely missing. Because of this, I constantly have to manually copy text and jump into external translator apps instead of using the built-in iOS translation feature.
33. [R81] 3/5 · US Great potential: I really love this app and use it daily to manage my work email. It has a ton of useful features but unfortunately some bugs they seemed to never addressed really take away from the experience. Specifically with dictation. You could dictate a whole long paragraph and it also shows up on the screen perfectly and then the second you turn off dictation it delete random words so you h
34. [R90] 3/5 · US Great, but dictation is awful: I'm only giving this app three stars because the dictation feature is awful. It often duplicates sentences, leaves out words, and substitutes incorrect words. It is far, far worse than the dictation in the default Apple Mail application or the Gmail app for the iPhone. I dictate a lot of my replies, so it's gotten to be a showstopper. Very unfortunate, I really like
35. [R157] 3/5 · US Email composer window on iOS: Been using the app for years. However recently my native iPhone keyboard constantly covers up the email body/composer so I cannot see what text I am typing. I am forced to send emails via Gmail instead of being able to use Spark, or I have to use my laptop like it’s 2004. My app is up-to-date and I’m being told it’s a known issue with Spark’s design on iOS. Very very
36. [R12] 4/5 · US Fix Adding Recipients To Email: Lately, I’ve noticed that when I go to compose an email and start typing in the “to” line, no names populate for me to pick. I have “full access” to contacts enabled but it doesn’t pull any names to me to view or choose. Can this please be fixed?
37. [R22] 3/5 · US Useful, but it drains the battery too much. So I uninstalled it eventually; it used almost half my battery. · translated
38. [R209] 3/5 · US App stays in background for an insane amount of time!: What is going on with this, it has been over a year that every time I check the battery usage Spark has an insane OVER 8hr in the background? I have background refresh for it turned off yet it doesn’t care! What are you doing for that long? What data do you need that you don’t already have from scanning our emails? It has impacted the battery
39. [R14] 1/5 · US No reply all?: The latest version provides no way to reply all. Only reply or forward are provided. I certainly hope this is an oversight and not a feature. If a feature, I’ll be switching email apps.
40. [R83] 4/5 · US Like it, but don’t love it: I REALLY HATE THAT ALL EMAILS ARE IN CONVERSATION MODE. Individual emails, pease!!!
41. [R85] 2/5 · US Better than apple?: I guess so but for all the supposed fancy email features it can’t even manage a reply to last sender in the thread. If you reply a second time it will automatically force reply to you every FREAKING TIME no matter if you reply to the specific email or the thread. Very amateur and makes me wonder what else it’s missing even through I’m on the highest paid option.
42. [R7] 1/5 · US peace in non-politics: This app refuses service based on the user’s country of residence. After installation, I was shown a message stating that services are not provided in Russia and Belarus, and that users from these countries are no longer accepted. I consider this discriminatory and unacceptable for an email service, which should function as a neutral communication tool. If the developers d
43. [R28] 5/5 · US Great email organizing app!: Spark is my favorite as it is easy to use, is non tech friendly (though very technical and advanced). Thank you!
44. [R32] 5/5 · US Simplicity: I like the simple format of how the emails are presented. This simplicity allows me to rapidly scan my emails and make rapid judgments about which are important and how to react to each email.
45. [R39] 1/5 · US Make it simple: To complicated and AI dependent. Needs to be more polished and less busy. At this moment, this is not for me.
46. [R35] 1/5 · US Not a good match with M365: Setup my M365 account on my iPad and it worked great, when to but when I did my iPhone it would only do IMAP, which is not supported in our account. No clue why this happened. Cancelled trial and deleted on both. Outlook for the win
47. [R45] 1/5 · US This app sucks: This app only worked for a month or so. I kept having to log in over and over again. Then it wanted me to verify my account but never sent the link . Now I just use my browser. Don’t waste your time or money
48. [R60] 1/5 · US Every few updates they log you out and wipe your settings: Love this feature. Having to dive thru setting every 10 months to get it back to how I liked was awesome. Definitely canceling my subscription and moving to native Apple Mail, past few years have been this app, which I loved, slowly getting worse while Apple gets better; seems like we’re at the crossing point.
49. [R63] 1/5 · US Can’t connect with exchange email server: Can’t connect with exchange email server and help bot is useless. Need to find another email app that will work with exchange.
50. [R69] 3/5 · US Overall this is GREAT!: I have used Spark for almost a decade now. I love everything about it. I will say, I strongly dislike the fact that you have to pay for a subscription in order to block a sender. One of the most basic worldwide email functions is blocked unless you pay a monthly fee. I am considering jumping ship and moving to another email because of this.
51. [R82] 2/5 · US Money grab: It’s got a good layout and fairly easy to navigate but the fact that you have to pay for a subscription to do basic things like unsubscribe from email chains or even block email accounts is really stupid and proves that this is a cash grab. This app made me switch back to apples native email app.
52. [R79] 1/5 · US Terrible: You can’t even get any notifications when you have email completely useless. I uninstalled this app.
