Was great, now useless
     
by Weather Challenged · July 2, 2026

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 well keep moving on and not waste your time

Missing core functionality
     
by Moon_shadow2973830 · July 2, 2026

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.

More frequent bugs
     
by rubikzyz · June 27, 2026

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 open the email again. Sometimes it works normally after reopening, but other times the same issue happens again.

Sub par experience in the last few months
     
by anishad77 · June 30, 2026

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.

Locks up and gets stuck every day on brand new iPhone 17 pro max, daily.
     
by HRH1234567889 · July 3, 2026

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.

Unreliable
     
by rob21222 · June 26, 2026

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.

Fix Adding Recipients To Email
     
by Petersen113 · June 24, 2026

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?
