Awesome Support Team!

I’ve been using Spark Mail across my devices, and it’s easily one of the best email clients available. The interface is sleek, the Smart Inbox and scheduling features are incredibly useful, and overall it’s just super intuitive to use on macOS.I recently ran into a syncing issue on my Mac, but the support team — especially Inga — was amazing. They responded quickly and guided me through the troubleshooting process. Turned out it was related to a setting in my antivirus software. Once fixed, Spark has been running flawlessly.Huge thanks to the Spark team for building such a great app and backing it up with outstanding support. Highly recommended!

The Best Email Client & App. Period.
Yogesh Kumar Dabas
I’ve tried nearly every email app and client available—both free and paid. Some are overpriced, while others are free but missing essential features. If you’re serious about managing your email efficiently, look no further. Just download Spark and relax. It’s easy to learn, intuitive to use, and packed with all the features you’d expect. If you need AI tools or team collaboration, Spark’s pricing is very competitive compared to others. As a free email client, it’s simply unmatched.

The best email client I have ever used.

Spark interface is very user friendly and intuitive. It is very easy and convenient to use multiple accounts using Spark. Features like blocking, categories, scheduling, snoozing, pin, etc. are very helpful and makes using emails much productive.

Spark Classic / Spark Ai

I have been using spark for over 5 years now. I have tried many email clients but this is by far the best email client i have used so far. Its quick (The shortcuts are insanely customizable), easy to navigate and has some of the best features (smart email filter system, integration with evernote, Built-in calendar etc)Some areas where i think they can improve: 1. Spark Ai somehow does not include features i mentioned above, which is quite sad. Hope they bring them up in their next update2. Accessing an excel file on the Mobile app is not friendly at all. For some reason its difficult to switch between sheets and the file moves up. (Probably the biggest fault in the app)
