Chuck
Chuck is highly effective for bulk email cleanup and achieving inbox zero, but recent updates and a shift towards a paid model have introduced significant bugs, connectivity issues, and user frustration with the free version's limitations and subscription practices.
Chuck is an email management app praised for its ability to quickly clean out thousands of emails by grouping them by sender, subject, or time. While many users find it transformative for achieving inbox zero, recent reviews highlight issues with app stability, email syncing, and a restrictive free tier that often pushes users towards a paid subscription.

Who it's for
This app is for individuals overwhelmed by thousands of emails who need a quick, one-time bulk cleanup to achieve inbox zero R14R17. It's particularly useful for those who appreciate grouping emails by sender or subject for efficient deletion and unsubscribing R4. It is NOT for users seeking a stable, full-featured daily email client, those who rely on Office365, or those unwilling to pay for core functionality R24R27R76.
Evidence note: The recent reviews skew significantly negative (0.34 recent-negative), which contrasts with the high lifetime rating of 4.76. This suggests a recent decline in user satisfaction, likely due to new bugs, changes in the free tier, and subscription issues. The developer's notes mention 'Performance and stability improvements' and a 'generous daily email cleanup quota', but recent reviews directly contradict these claims, with many users reporting crashes, instability, and restrictive free features.

- [R4] 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!
- [R5] Easiest way to bulk clean email: I finally got to inbox zero! Ready to use app to get your email inbox cleaned out. Highly recommend. The free version is awesome
- [R14] 30k+ email removed: Was super bad at keeping on top of my emails to the point where wanting to clean up was an extensive effort. In less than 10 minutes I had over 30,000 emails removed and now I can keep better track of the emails I’m looking for.
- [R17] Effortlessly clear your inbox chaos: Chuck is an absolute lifesaver! With over 75,000 emails clogging my inbox, I was drowning in digital clutter until I discovered this app. Within minutes of installing it, I was able to reclaim control over my email with remarkable ease. The intuitive interface and powerful algorithms effortlessly sorted through my messages, distinguishing between what was impor
- [R9] Wow!: I had no idea of how many subscriptions I had joined over the years. Chuck makes it so easy to unsubscribe and to delete mail!
- [R15] Great app: This is the app I use when I want ( I mean, need) to make short work of paring down my inboxes and clearing out the clutter.
- [R55] Best email clean up ever: Best email clean up app ever! With over 63,000 emails I had given up. You can unsubscribe, delete, and block senders. I tried the free version for a few days and had no issues I’ve had with other email clean up apps. Small fee is worth a good email address.
- [R71] Feeling Lighter: Had too many subscriptions and emails coming in daily
- [R13] 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.
- [R38] Crashes on Apple account: This issue seems to have popped up since I upgraded to iOS 17.1. I’m working with support but so far nothing. Still works for my Google accounts. UPDATE: Support has worked with me and now, Dec 22, 2023, I’ve updated to iOS 17.2 and re-installed Chuck. It’s working again for my iCloud account. Thanks!
- [R1] Starting to have issues with credentials: It keeps kicking me out with my credential
- [R21] 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.
- [R24] If it was not buggy: App is very appealing easy to use but lately it gets disconnected from Gmail and fails. Only using the free version and for personal use. Everything they offer paid version I have it on iPhone mail app already so not for me
- [R30] app keeps closing: the app doesn't clean just closes automatically
- [R2] Only deleted on phone: I was excited to use this and it seemed that it was easy and worked well. On my phone, thousands of emails were removed but when I logged into my email on my laptop, nothing had changed. I tried reaching out to the email they provided and it got returned.
- [R20] Chuck doesn’t do anything: I’ve used this for a week, be difference… senders I’ve blocked keep coming and there has been no change. I wished it worked because I hate all the spam and nonsense
- [R50] Old emails showing as new: Two major issues. (I was using pro) Did a cleanup…and discovered it didn’t remove emails from the server…so you only get results if you still use the app…it does kinda make sense but it’s unexpected., this is the big issue First Emails from my friends from 2018 show up as coming in “yesterday” - this is by message not by sender. And then I got spam emails that hadn’t
- [R65] Was great when working: Worked great at first but then it stopped loading emails, even ones from the same day. Also, the unsubscribe from the app (not the emails) says it sends an email request to unsubscribe but then it blocks the emails from Chuck. I see the notification for them sometimes but then it’s not in the actual inbox it’s like it blocks the sender from chuck.
- [R8] What’s so great about this app?: Not sure why this got high ratings. To use the free version you can only have one email account otherwise it’s $39.99/year to add other email accounts. No thanks.
- [R12] Great app, but...: I ran across Chuck in the App Store and downloaded it out of curiosity. Then I started playing around with.it and I love it! Just one small problem--when I went to.dump the spam and the trash, all I got was an.ad to buy the pro version. If I can't get rid of all the junk without paying you for the "privilege", what good is your free version?
- [R22] Misleading: Free version doesn’t allow any mass deleting. So it’s just a preview to get you to subscribe for a monthly fee. I have no problem with that except it’s not honest up front that it is subscription based for even basic functions
- [R60] Have to pay to add accounts: Not worth my time or energy.
- [R3] Not a 7 day trial. They will charge: Downloaded the 7 day trial and was charged 39.99 immediately. No refunds allowed
- [R7] renewal timing issue: First, it bears noting that before I started ‘chucking’ emails, they were a big problem. I’d let thousands accumulate. Then spend hours deleting all but a small handful one by one. I resented, even hated, dealing with email. I now check them as much as daily. Always quickly. In other words, I love this app. Having said that, there is a problem. Renewal timing. I
- [R47] Still charged me but cancelled a week ago: Both Apple and Chuck will not refund me. My income was stolen from me and. I was charged 39.99$. Customer service will not help.
- [R230] Would Have Been 5 Stars: I was really excited about this app and it’s fantastic features, till I ran into a problem when attempting to upgrade to pro version. I get a message saying subscription successful, then another stating that the app can not connect to App Store so none of the features of pro are active. However, I look at my subscription list and there is a subscription active! No other ap
- [R23] Not useful for unsubscribing from mailing lists: Someone email bombed me this morning, and I downloaded Chuck to try and help unsubscribe from the 500+ new lists in my Inbox. Unfortunately, Chuck only identified less than 10 of them as new mailing lists. Surprising, since most of the other 490 have the subject like of “Confirm your subscription”. No apparent way for the user to select emails to
- [R63] got this app to unsubscribe from senders: didn’t work as advertised, i keep getting the same amount of marketing emails from the senders i’ve unsubscribed to. even chuck will say “you are not subscribed to any lists” and i will STILL receive emails from mailing lists i unsubscribed from via this app. don’t waste your money.
- [R61] Perfect interface for cleaning inbox but slow loading: Nicely organised interface far superior to other email clients for mailbox overview and cleaning. Significant frustration though is slow loading speed when you select a message to read - email body content that shows instantaneously in Outlook can take several seconds, there is even an animation showing progress. Messages should surely be load
- [R80] App does Great: App does great job but if the developer can please fix when opening an email through push notification it never shows the email even after waiting several minutes. This has been happening for several months.
- [R98] Very buggy: I’ve been a paying subscriber of this app for quite a few months. It’s not worth it. The app is buggy and glitchy (whenever I open emails from notifications they are slow to load/will never load). It’s not well designed and the UI is not great. It’s hard to find anything. The only redeeming factor is it can clean up your email a little but most of the spam that I tried cleaning up
- [R18] Why not 1 button to erase all. I’m an adult. Let me have control of my mail.: Why not one button to erase it all. I’m an adult. Let me have control of my mail.
- [R19] Just needs these features added: 1. Folder Management 2. Privacy features like biometric login/locking 3. Creating and maintaining rules to 4. move/delete/handle emails in a certain way 5. Better text formatting like being able to create a bulleted list 6. Appearance of app changing 7. Ability to set a default email to send messages from The app works great aside from not having these features.
- [R25] Piece of ****, loses your email drafts: I have lost tons of work by trusting Chuck to not delete my drafts right in front of my eyes. Turns out if you write a long email and then change email addresses, it just deletes everything for no reason. Full stupid
- [R27] Weak invite support: If you’re just trying to reach a zero inbox, app is great. But if you’re using it for work daily, not being able to accept calendar invited inline, etc gets in the way of productivity.
- [R33] Dumb: Won’t let me sign in to my iCloud.
- [R41] Not Working with Apple Emails: My main email is Apple, and I've been trying to troubleshoot why I can't get my Apple email linked to my paid Chuck subscription. I've gone through all the steps to create a third party app password through my Apple ID and it still says the password and email doesn't match. I've requested assistance through a format that isn't email, but I am forced to troubleshoot
- [R43] Can’t add Gmail account: This a great app that worked flawlessly for over 2 years. Now it doesn’t work at all because it won’t allow me to add my Gmail account. The problem is clearly on the handoff from Google authentication to the Chuck app. There are no issues with my Google account and I’m able to successfully add my Gmail to other iPhone email management apps. This only happens with Chuck ove
- [R76] Confirmed: Does NOT support Office 365: The screenshots advertising Chuck and Chuck’s FAQ show it supports Office 365. That is NOT true. Chuck support confirmed to me that they have stopped supporting Office 365. Fine… but why advertise your product and include configuration steps for Office 365 in your FAQ if Chuck does not work with Office 365?
- [R58] Keeps losing connection to my mailboxes: When I first got Chuck it was a big help to clean my mailbox but it keeps losing connection to my mailboxes and because of that I have missed a couple important emails. It was pretty disappointing. It has also been very slow recently. :/
- [R95] DOESN’T WORK: I’m young and am great with everything tech just in case you think I’m an idiot who doesn’t know how to work the app. Inbox was packed. Tried deleting things with this app, and yes “permanently” deleting things as the app warned me. Nothing deleted. On my email app all of those “deleted” emails were still there. Great. Thanks. Spent a half hour dinking with it to no avail.
- [R101] Not deleting: I have tried to send a email through the app setting but it was rejected. The app says have no more emails but though my email app doesn't detect them too. I have pictures to prove it.
- [R79] Was amazing…: I’m getting spam emails that I unsubbed from in notifications. When I click on them the email is nowhere to be found so I can’t even try to block them. Too bad because I loved the app
- [R104] Need Office365 Support!!!: This is a great app, but it needs support for Office365 login! Not Outlook, not IMAP/POP
- [R233] Only supports 5 specific email providers: Being a huge fan of Mailstrom I was excited at the prospect of being able to better manage my inbox from my phone. The feature list specifies 'Works with Gmail, Outlook, Yahoo!, iCloud, Aol and more', but as far as I can tell only those email providers are supported at the moment. It might be great, but sadly will have to revisit once they add IMAP support
