  1. [R11] Chuck 5/5 · US Email is forever changed: In 2 days I was able to delete 120k emails intelligently, leaving me about 6000 remaining to sort and the rest of my important emails archived. Not just an amazing cleanup tool, the compact email view allows me to see so much more of my inbox. The groupings by sender, subject, etc are amazing. Through the process I found loads of emails I missed directly to me, oops. Chuc
  2. [R53] Chuck 5/5 · US Keeps inbox clean: I love this app, it’s easy to use and is better then others I have tried. I like the email grouping function.. I can move or delete emails from one sender at once.. I also like the unsubscribe and block function right at the top of the email.. so tired of having to find those links within each email. It’s 100% worth the 3.99 a month to manage 2 email accounts!
  3. [R26] Chuck 5/5 · US Free tools and FANTASTIC!: I had multiple thousand emails clogging things up and this app consolidated them by sender, so I could address all 963 of the daily spam emails from XYZ company all at once by selecting all and then deleting. My email has no more notifications for the first time in years, all without paying a dime! I will definitely enjoy this app for years to come!
  4. [R81] Spark Mail 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.
  5. [R17] Chuck 5/5 · US The best app for keeping my inbox clean and organized: Chuck has made managing my email so much easier and faster. It lets me clear out huge batches of messages with one tap and helps me stay on top of everything without feeling overwhelmed. The interface is clean, the features work smoothly, and the unsubscribe tool is incredibly useful for cutting out junk. I love that it supports all my account
  6. [R21] Chuck 3/5 · US Great for organizing your email box: I had high hopes for the app as a replacement for the iOS Mail app but I found out that is has a lot of bugs and limited in features. Their support was responsive though. I think if they keep it up it can be really good someday.
  7. [R27] Chuck 3/5 · US Was ok for a while: The app worked plausible up until the other day. Then it just locked up and stopped working. Tech support had the usual remedies. Up date the app, which it already was, or delete and start over. It wasn’t that user friendly to begin with so why go through the motions again in less that a year of use. Made me decide not to purchase the upgrade.
  8. [R69] Spark Mail 3/5 · US Nice most of the time, but attention to detail is lacking: Using spark is a pleasant experience 99% of the time. But there are a lot of bugs and small things that annoy, the app randomly freezes on a white screen, emails aren’t cached and take a while to load, search is noticeably worse quality than Gmail, and emails with wide HTML content can’t be zoomed out or scrolled horizontally. I still use
  9. [R1] Chuck 1/5 · US Notifications inconsistent: Notification banners always go through, but more often than not, no unread badge and mailbox is not refreshed till I open it. I do not experience the same behavior with Spark. I already emailed support. Funny thing is, it happens sometimes.
  10. [R4] Chuck 1/5 · US Really bad: I don’t know why I haven’t deleted this app sooner. Every single time I get a notification that I have a new email, I click it and it does not open the email. It brings me to a screen with other emails. I try to click through the different ways to filter them but it’s always a toss up if the email will show up or not. I usually end up opening the actual website after for my email that
  11. [R13] Chuck 2/5 · US So buggy: This app gets buggier by the day. I have one Gmail and one iCloud account registered. Over time Chuck simply stops syncing with one or the other of those accounts, and the “re-authorize” feature doesn’t nothing perceptible to improve that. When I try to sync, I just get and endless spinner icon with no errors, no updated email messages, nothing. Recently in desperation I uninstalled Chuc
  12. [R64] Spark Mail 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.
  13. [R31] Chuck 1/5 · US What happened: Pretty wild that their monthly cost went from $3.99 to $6.99. Forced me to reevaluate email tools and quickly realized much better options exist these days. Edit: they emailed me to say they had reduced their price, it’s a whole buck cheaper. /s
  14. [R90] Spark Mail 3/5 · US Nice app but… subscription.: Spark emailed is a clean and well-crafted email client that features easy email manipulation. However, it’s hard to recommend because you’ll be paying yearly forever due to their subscription service. It’s good but not that good. There are too many great free options that have some of the same features as Spark.
  15. [R5] Chuck 5/5 · US Best way to get to inbox zero quickly.: New update as of May 16, 2026: Super responsive developers who clearly care about keeping Chuck users happy. I’ve submitted bug reports on two separate occasions, and both times the customer service reps have contacted me in a very timely manner to resolve the issues. I’m still not thrilled with the new translucent interface (the previous style was a lot e
  16. [R76] Spark Mail 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. [R82] Spark Mail 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
