Absolutely non functional

Ok a slight exaggeration, but when I open the app to check the 1 message I have, then 8 messages download with timestamps from two hours ago… you know some people use email mostly for work. Getting those emails in a timely fashion and acting on them is critical. I love almost everything about em client, but not ground your mails… might as well be trying to use a calculator app to manage my email.

Response from developer

Hi, thank you for your review. Unfortunately, new messages can only be downloaded once you open the app. Apple allows background syncing for its own apps (and some selected big names, such as Gmail) but not for third-party apps like eM Client, so the actual download of the message can happen only once the app is opened. To be notified about new mail in the meantime, please make sure push notifications are enabled in the app (Settings > Accounts > your account > Preferences > Notifications > Use Push notifications) and allowed in iOS (Settings > Notifications > eM Client > "Allow Notifications"). The notifications should show up in real time, and then when you open the app you get the full message. If new messages still reach you late, please contact our mobile app support team at mobile@emclient.com with your OS version, app version and the email address and email provider of the account this issue happens with, and we'll be happy to look into it. Thank you!

Too many top actions take too many steps

While the user interface is good, too many of the most common email handling actions take more steps and are more buried than Gmail and Outlook mobile apps. Junk and Phishing need to be very easy actions, not buried 2-3 steps deep. Swipe actions in message lists need to be configurable. A long-press popup menu with favorite actions would also help. Folder sync needs to be smarter, keeping inbox up to date every few seconds while syncing all the other folders can usually wait several minutes.

Response from developer

Hi, thank you for your review and for the detailed suggestions. Swipe actions are already configurable in Settings > Preferences > Swipe. For quicker access to Move to Junk, you can add it as a swipe action (swiping then shows three options: Move to Junk, Move to Junk and blacklist email, and Move to Junk and blacklist domain), or add it to the toolbar that appears when you select messages in Settings > Preferences > Toolbars > Mail > Multiselect mode - you can add any other actions you use often there as well, which you then activate by long-tapping any message. If you’d like more than one swipe action for each direction, feel free to vote for the related request on our Sleekplan: https://emclient.sleekplan.app/feedback/144133. Folder sync already works this way: the Inbox and the folder you open are always synced first, and the other folders follow the sync interval. For IMAP accounts, all Inboxes use IDLE connection, which means we should know about any new message right away because the server should report it immediately. If your Inbox doesn’t stay up to date, please let our mobile app support team know at mobile@emclient.com with your OS version, app version, and the email provider of the affected account. Thank you!

I would away - EM client scans your email for content

Oct 2026: the email client forcefully scans all your emails for content using some sort of AI. Even though you can use the option to turn it off, it does not actually turn it off. PUSH notifications are disabled but nothing changed.
The Support claim that it doesn't, but it still scans the emails and applies tags based on the content. This is not a privacy focused app, and in fact it's quite the opposite it is anti-privacy. Under no circumstances would I recommend this email unless you wish to give your email content to this company.

Disabled Touch Screen on iPhone

Sucks. Touch screen disabled on app after update and reinstall.

good but...

the inbox refreshing is ridiculously slow, even for just 1 account

Finally found it - the perfect email client?!

I have been searching forever, seriously. I’ve been on iPhone, Android, Windows, Linux, back to iPhone… I finally found what I’ve been looking for.

An unrestricted, multi-IMAP, responsive, modern email client that “syncs” well between desktop and mobile.

Love the clean layout and organization. Puts all the platform built-ins to shame.

Not integrating properly

I’ve tested eM Client and used it for over a year. After this long trial, I’ve decided to move back to the Apple Mail app on both iPhone and Mac. The client never integrated smoothly into my workflow — syncing was consistently slow, and recently it even started returning previously deleted emails back into my inbox. At this point, Apple Mail is simply more reliable for everyday use.

Sync too slow

I love eM Client on desktop, and have a paid subscription, but I’m switching to Canary Mail because eM Client’s iOS app is painfully slow syncing every time you open it up. Sometimes I need to access an email quick and I’ve been having to use Apple Mail instead of waiting around (up to 30 secs!) for em Client to update. Pity — I like the desktop apps so much but I need a good iOS app too. Snoozing doesn’t sync between desktop and iOS either for iCloud.

Email Issue with was resolved

An issue with this app unable to download and display mail was resolved by deleting the app and doing a hard restart of my iPad. Then reinstall. The app is quite good and it has replaced the Apple Mail app or my email on my iPads and phones.

Response from developer

Hi, thank you for your feedback. We're sorry to hear you've had issues with the app. Please reach out to our mobile app support team at mobile@emclient.com and let us know your OS version, app version, and which providers' accounts are affected. We'll make sure to look into it. Thank you!

Come on

Editing to add: I emailed you people prior to this review with these concerns, and you said the exact same thing, none of which fixes the issue. I also told you I’ll just leave an honest review, so I honestly don’t know why you’d simply scribble the same type of nonsense into here unless you just want people to THINK you’re responsive with alleged solutions. Original review below.

There is no reason - none whatsoever - for A: inbox refreshes to take such a pathetically long time; and B: basic search to take such a pathetically long time. I have seen a number of “responses” from devs saying that it’s being worked on, but as of now that just seems to be a balloon full of air instead of anything of substance.

Excellent!

I have the desktop version which is great as well. This mobile version is loaded with great features. Definitely blows away the other mobile email apps I have tried.

Slow and unstable at times

Areas for improvement: a) iOS client is v-e-r-y s-l-o-w to retrieve Outlook and Gmail accounts (especially Outlook) and at times becomes unstable when sending AND receiving - your Mac and Windows desktop clients work well in comparison, b) combined inbox does not work in iOS - need to click on individual accounts to view inboxes (annoying), c) AI features: personally, don’t care about these (I do not use the slop generator, I appreciate grammar check/continued spell check that is not intrusive). LOVE your security/priavacy features (ex. your pixel handling) - please maintain this as your focus. Recommended recipe for success: please focus on: 1) security and 2) stability, then 3) whatever else you like - e.g. AI slop (in that order).

Hi, thank you for your feedback. We're sorry to hear that your experience with the app hasn't been smooth. If you're experiencing synchronization issues, please reach out to our mobile app support team at mobile@emclient.com and let us know your OS version, app version, and that your Outlook and Gmail accounts are affected - we'll be happy to help you troubleshoot. Regarding the combined All inboxes folder - please mention this issue to our support team as well, we'll look into it. If you're not a fan of the AI features and don't want to use them, we will always keep the option to disable them. But many users do rely on AI now, so we try our best to provide it in a useful but secure way as well. We're glad to hear you like our security and privacy features - please rest assured that we plan on prioritizing user security and privacy going forward, as we always have.

Latest Version Doesn’t work on iPad

The latest version of this app doesn’t work. Mail on primary and secondary accounts only displays one mail item. Incredibly, the same mail item.

I reinstalled it…worked normally for two days, then the same problem. It’s serious and it’s unusable in its current form.

so much better than the usual options

gmail stalls out constantly. apple mail also bugs out all the time. but finally tried this one and what a breath of fresh air! it’s almost weird having a reliable email client :)

Great features but app is unreliable and unusable

I've used em client on Windows since it began and pay for it. Great features and design. It is my favorite desktop email client by far. It is also quite good on Android.

The iOS implementation which I run in iPad mini with iOS 26.6 is unusable.

It freezes. It doesn't send emails reliably. It takes forever to download emails. It's formatting goes weird, with message headers in the account view inexplicably indented at random. I need a reliable, predictable, stable email client for my work.

I'm very saddened that I have to go back to the inferior Gmail app.

If anyone reads this, I suggest also that you find a way to implement the official Gmail API like Wundermail does. It will affect problems to do with aliases (across the desktop Windows environment too).

Thanks to the team at em client, and I hope that you are able to get the iOS version to the same excellent standard of your Windows client.

No useful calendar

I gave it a one star review to try to get the attention of the developers because they don’t seem to get it. If we get a calendar link in an email, we can only put it in a stupid local Calendar on that device. What use is that? And their share option doesn’t go to Calendar, as any competent programmer would do. Seems to be no way to add to your calendar.

Response from developer

Hi, thank you for your feedback. We're sorry to hear that your experience with the app hasn't been smooth, but you don't need to use a review to get our attention. You can always contact our support team at mobile@emclient.com (for the mobile app specifically) or info@emclient.com (for the desktop app or generic questions) in case of any issues, and we will be happy to assist you. Please reach out to our mobile app support team and let us know which synced calendar account you have set up, so we can help you troubleshoot and find a solution.

Calendar

Can you improve the calendar? Now the calendar do not shows days number?

Finally a better Mail client

so far the best proper email client I have come across for iOS. Previously I used K9 when I had Android. eM Client is as good as K9.
I did some tests to verify that the IMAP & SMTP connections were sent from my IP address when using this client and these were, instead of being proxy through somebody else's service like so many other clients do.
I can actually see the full source of the emails and head as I so wish. Push notifications don't work unless you use the push notification through their servers, but unfortunately this is only limitation of iOS. So far so good.

So much better than outlook

Took off a star because there doesn’t seem to be a watch for reply option on mobile but otherwise this app is great, I’ve completely switched over from outlook which is nothing but frustrating. Also needs a way to create an event from a date in emails

Response from developer

Hi, thank you for your review - we’re glad you’ve switched over and are enjoying the app! Watch for replies is actually already available in the mobile app: while writing a message, tap the eye icon in the bottom toolbar of the compose window. If you don’t see it there, it’s under the three-dots icon in the bottom toolbar, and you can make it always visible via the three-dots icon > Customize toolbar. You can also turn it on for a message you’ve already sent: long-tap the sent message > tap the three-dots icon > Watch for reply. Detecting tasks and events from emails is planned for the mobile app as well. New features from eM Client 11 are being brought to the mobile app incrementally - just like with the development of the mobile app as a whole, we have to add them in smaller waves, as too many big changes at once can cause unexpected issues across different devices. Mobile platforms are also more restrictive than desktop - this affects even how quickly Google and Apple allow us to push out updates if something goes wrong - so we always have to weigh priorities and move in smaller, more careful steps. If you have any questions in the meantime, feel free to reach out to our mobile app support team at mobile@emclient.com. Thank you for your understanding!
