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.
Does Spark have AI features?
Yes. Spark uses AI to write faster, reply clearly, and summarize threads. On Plus, AI helps you make better inbox decisions. On Pro, it acts on your behalf — drafting, organizing, and following up.
Is Spark good for team collaboration?
Yes. Teams can share drafts, comment privately, assign messages, and manage shared inboxes — no forwarding chains. Collaboration is available on Pro.
Can I schedule emails to send later?
Yes. Schedule any email to send at the right time, or snooze incoming messages to return when you're ready.
Is Spark free?
Yes. Spark is free to download and use. Spark Plus is for professionals who want a more focused inbox; Spark Pro is for those who need Spark to handle follow-through so nothing gets missed.
Is Spark available on Mac, iPhone, and iPad?

I wanted to Pay you guys, so bought PDFExpert Premium

What do I say! Not everyday you come across products where you want to pay for them by yourself. Like literally desperately. And all this because I dont want Readdle to close down ever, for lack of cash. Anyway, this is hands down the best eMail client on iOS. I have tried all the other ones and they have one or more limitations, for example the next best one is Outlook - great design, features etc., but it wouldnt allow to pick up attachments from iOS ‘files’ app. Its small things like these. You guys have paid so much attention to every single thing. I had long been a big fan of Inbox by Gmail.. and I cant think of why they decided to shut it down. Who takes such funny decisions in Google? I am hardpressed to think of any feature request for Spark, however if someone puts a gun to my head and asks me for one, it will be one of the features from Inbox - of categorizing mails by their content - Travel, Finance, Shopping etc. Thanks a ton and please ensure that you guys keep on thriving and surviving.
Freezes too often, irritatingly so
Parekhmr
I used to love Spark for the longest time. But something happened in the process of them upgrading their app for adding more collaboration features - it has started to freeze almost at all times. Extremely irritating for an e-mail app and this puts users off big time. Fix this guys or you all will soo be history. I want my e-mail app to just work the minute I launch it - shouldn’t have to wait around looking at the screen to even access emails. It freezes on launch and if you have it open, everytime you access it. Really irritating.

Thanks for a useful email app
Thanks Word
I was having problem in attaching documents to my mail in outlook installed in my iPad. Lot of complaint to MS yielded no result. After lot of search for a suitable email app, I found this email app. After using this app for few days, I found this app as extremely helpful, attaching documents were not a problem at all, moreover it provided the facility to change colour of some of the sentences/words in my email. My only request to the developers is is to add the facility of adding an image within the Mail body. Thanks to the developers for creating this useful app.
In this update:
- Attaching files from Google Drive is now more reliable, with a redesigned file picker.
- Fixed an issue where Microsoft and Outlook calendar events could show at the wrong time in some time zones.
- Fixed an issue where the Spam folder could get stuck on an endless loading spinner on Outlook accounts.
