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.
How is Spark different from Apple Mail and Gmail?
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.
How does Spark help with email overload?
Spark surfaces important messages first, lets you snooze emails until you're ready, and helps you reach Inbox Zero without the grind. Higher plans flag what needs attention so nothing gets missed.

Okay, I love Spark and it is a great app. But, every time when I’ve got a mail and trying to open it from my lockscreen Spark is showing nothing, just a grey screen. I have to close and open app again to see my mail. I am using iPhone XS with recent updates. I am still loving my mail (again), but with a little bit less power. Until you fix that bug.Little update: I can’t find the calendar. At first. I had to Google where to find the calendar after some updates. Also, not all scheduled meetings are shown in it. For example, on desktop version I can see all meeting, but on mobile only some of them. I don’t know why.
The app became so annoying, with be blocked features that I can't just turn off

Hi, dear developers. I love your app and think it's so incredible. But after update to version 3, it's became so many annoying things. The app wants me to set mail is Done, when I wants to make it Pinned. I wanna remove an Email and it says to make it Allowed. And I just can't do what I want exactly to do. So often I just have to do what it says and have no other choice. Just do some thing and then in 99% of time I'm getting to the page to but a Subscription. Yesterday I was navigated there 7-10 times per day. Now I can't use normally phone App and trying to use more Desktop old version. Do something please. Because now I and probably some other people think about getting alternative email product that won't do what it wants without asking. Thank you

Spark for me

Spark this is the best Mail client that I ever see. I saw a lot of the same apps, but spark the best. Why? I like the most minimalistic interface and a lot of tools that I can use. I think spark creators can add some new tools. So this is some new themes. Now in spark we have just two themes dark & light. I think spark creators can add blue, red or probably some green theme and so one. This is my idea. And spark creators can add some tools position change. So we have some tools, in my opinion spark creators can add tool to change tools position. In general Spark the awesome app that I use every day.
In this release:
- Spark now adapts to resizable iPhone windows.
- Fixed several issues with Siri in Spark, including recipient fields getting cleared when adding an address, and New Senders messages being read as if they were your latest message.
- Fixed several crashes, including ones that could occur while composing a message or using Siri shortcuts.
