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.

Best mail client I can find
Keroghee
I tried google inbox, outlook, Apple mail and Newton. This is the best one in comparison, very simple and intuitive, has just the features you need and nothing more. I’m also using it on MacOS too.
Bad support for faulty application
Hanozz
Despite the company developed the Spark is known one, they have a bad support who is not responsive to customers several emails concerning an important issue in the basics of simulate applications, I have a sending problem on iPad and contacted them many times and they just send a links to read in case I can find a solution which it is not worthy to read even, and no one care to discuss the issue and solve. I will stop using this faulty application - how come an email application is giving an error when you send an email :))) 😀.

Very Close to be rated 5 stars if few key features are developed
wildkimo
Outstanding after sales support response.Missing: Attaching an email item while creating a new email.Lack of calendar functionality if the email provider doesn’t support it. On outlook, you definitely have calendar even if your email provider doesn’t have one.The multi-threaded email view is often confusing, especially with long email threads. This should be an option, and provide a normal email by email view in the inbox rather than the cumulative email thread view alone.Few cosmetics would be appreciated, like more text formats, colors, etc.

We will save your email in our app wishlist and contact you in case the situation changes.Thank you in advance. Have a great day!Artiom
Spark now uses a more secure connection for Microsoft 365, Outlook, and Hotmail accounts, with one sign-in for email and calendar.
Already use a Microsoft account? Just sign in again when Spark asks. It takes a few seconds.
