Soo much potential but ...
I'm a long-time Spark Classic user looking for a solid alternative, and I found and tested this app. I give it 2.5 stars because the support is A+ 5 stars all the way and there's so much potential, but it fails to deliver for the following reasons:
1. Limited email sync history (should offer a Tier that supports unlimited)
2. AI spam filter needs much work, as it's not picking up very obvious spam.
3. The desktop and mobile apps are wrappers, not OS native.
Again, the team is A+, and I understand it's early stage and still in development, so I hope things improve once they address the issues above, but for now it's hard to justify the migration effort + cost.

Oct 16, 2026Hi, thank you for the honest review, and for the kind words about support. Feedback from a long-time Spark user helps us a lot.
On your three points:
Spam filter: if you can send me a few examples of obvious spam that wasn't caught (a screenshot of the sender and subject is enough), I'll have the team look at exactly why. The filter also has a sensitivity setting in the spam protection settings, so it's worth trying a stricter one meanwhile.
Desktop and mobile apps: the desktop apps are built with web technology, so I won't argue that point. The mobile app is in beta and we're still improving it, with an update coming soon.
Thank you for giving it a fair test. If any of this changes your mind later, I'd be glad to have you try it again.
