Just when you think the boundaries of email client design and delivery have been reached (Spark was hard to beat) along comes Spike! It combines the best of Messenger with a modern email platform and you get a fast, intuitive and fun to use App! If you’re a serious Business user, don’t worry, all the important background email type stuff is still there leaving you with an uncluttered UI to read threads as conversations! You can present your emails as the usual Inbox or group them by Subject or People! You can even create Groups so in effect creating Teams! Another big plus is the Developer has it ready for Desktop as well including Mac! I’ve made the App my default and feel part of a revolution in re-launching the email format! Great Work guys!

Great concept and delivery

This is the best email client I’ve used to date. It has many of the best features from Google’s Inbox plus many more great features. The chat look and feel and people bundling makes it very easy to navigate and search for things. And it has plenty of other nifty menu options to play with. There is a teething issue for some users, myself included, with adding an Outlook account but hopefully that will get resolved shortly. It would also be great to see a trip bundling option (like there was in Inbox). All in all this is a fast, feature loaded and innovative email application.

Apple Watch support coming soon..

Thanks for such a fast reply to my review that mentioned that being able to have the Spike app on my Apple Watch Series 5 44mm would be fantastic. The news that support for Apple Watch “is coming soon” is great to hear... After cursing Spike because I thought I couldn’t delete the trashed messages from a particular email account in one quick & easy action I have just discovered that I can by tapping on the little arrows... I’ll be looking forward to the support for Apple Watch arriving in the not too distant future! Thanks for a great email app. 👍👨

Developer Response ,
