FAQ
Is Spark the best email app for managing multiple accounts?
Spark brings Gmail, Outlook, iCloud, Yahoo, and any IMAP account into one unified inbox, so you can manage every email in one place instead of switching between apps.

Spark helps you focus on what matters, not just read email. It automatically prioritizes messages from real people, keeps newsletters out of the way, and can summarize, draft, and follow up so less falls through the cracks.

Community Voice & Feedback
Idk what yall did to break the app but now it’s show badge number just to be on zero it’s slow it’s moving weird. I never used apple mail in 12yrs but im think of switching 🤦🏾♂️
Spark used to be the only mail app for all my mac and ios devices. it has gone so down hill. very slow updating, crashes often and just plain terrible. i paid for the extra features for quite a while. use the core mail app its way faster and better.
Stopped working after 6 years of using it. It error out,”Account can't be added
If you're using a Google Workspace account, contact your administrator to ensure IMAP is enabled.”

Excellent and powerful app.
I really want to like and use this app! However, it stopped fetching email content reliably on all of my devices.
Sometimes it works, sometimes it doesn’t. I went through troubleshooting with my email provider and then attempted to do the same with Spark. Unfortunately, they were unable to be of much help.
So, I guess I am off to find a more reliable app for syncing multiple IMAP accounts on multiple devices. Two stars.

Please everyone read the negative reviews not the positive. There's no pop mail option. Frequent authentication errors with popular web services like Yahoo and Microsoft Outlook/Hotmail. Threaded view is unwelcome. There's inresolved Spark Android issues that remain. It used to fairly good but no longer. Maybe it's time for an app reset and re-engineer Spark by someone else.
I love this app. It is so versatile, I can delete 30 emails with one click. It manages my emails by categories. But the best thing about it is their customer service. They are so helpful and knowledgeable. This is a great app and I’ll never stop using it

I have been using this app for years and loved it until yesterday after updating to IOS 27. It will not print emails anymore. I am using the newest version, and nothing. I can print from other apps and Apple Mail, so I know it's not the phone or printer. Support, I need help here.
Retrieving email is extremely slow with this app. They keep adding features, but the app keeps getting worse. Very slow.
For the last several years, I have checked in periodically with Spark and begged them to introduce non-threaded emails. They simply do not work for a large portion of the population.
A month or so ago, my workplace actually BANNED Spark Email from being used because of security risks. Because Spark did not listen to their potential customers, I have no ability to try and show value to my employer.
Not listening to your customers is the beginning of the end, and my guess is that my employer is not the only one that has banned them because of security issues. At least so far.
Not listening = certain demise.

I could never get apple email to work. The key you put in has a mask and you can’t remove it to make sure your key was typed in correctly. Tried pasting the key as well.
Good software helps a lot. I like it a lot! Recommend for everyone. Just wish Ucraine flag would not be showing all the time. Kinda annoying
Really trying to love this app. I’m specifically using it with Microsoft 365, which is undoubtedly part of the issue. There are some persistent bugs that make the UX frustrating at times, but so far tech support has been amazing with their help. I’ll keep plugging away at the bug reports and will update my review as things improve.
The app becomes so much more buggy after the recent “AI update”. Just to name a few, I can’t paste in email address in a new email if there’s already an address. I can’t do control-option-v on a Mac client to copy without formatting. Attachments just randomly become invisible in incoming emails. Sadly, I’m jumping ship.
