What's New

Version 2.0.8

Hello again, everyone!
A small glitch in our build pipeline caused us to release a version of 2.0.7 a few days ago that didn't contain all of the fixes our release notes were promising.
We apologize for the back-to-back update. Rest assured 2.0.8 is a real deal.
Please enjoy the following encore presentation of our original 2.0.7 release notes:

Details matter. That's why today's update is focused on improving specific details on how you work with email in Spark.
## New
- Editing in Outbox while offline. You can now edit email in Outbox while you’re not connected to the Internet and all of the changes will be saved and sent once you’re back online.
- Improved the collaboration experience in Shared Drafts. You’ll see the name indicators on the top of teammates cursors while editing shared drafts.

## Fixed
- We believe we have fixed the annoying issue with Snoozed and Reminded emails. If not - just let us know right away!
- Fixed an issue with email parsing for specific accounts;
- More improvements for the state restoration of the app when it is opened from background.

We hope you enjoy the update.
Have a delightful, secure, and scrumptious summer!

Editors’ Notes

There’s no avoiding email—as much as we might wish otherwise—but Spark makes tackling an unruly inbox a whole lot more pleasant. The app is an immediate joy to use, thanks to a painless setup process and a sharp, clean layout. But Spark’s true value comes from its clever interface, flexible customization, and the way it bubbles important emails to the top while filtering out the noise. Inbox intimidation is now a thing of the past.

My Selected Mail App

Ken Bagby

I have tried many email apps as an alternative to a rather bland, but stable, Apple Mail. Purchased many; they looked so good. But every one developed one or more operational issues where I had to abandon them. I needed an iOS app which had a Mac app. When Spark came around, it just clicked. Features were great, functionality good, and was mostly, but not always, stable. This forced me to consider and then actually abandon Spark. Each time, I gravitated back to Apple Mail where the same blandness frustrated me. Communicated with Readdle and went back to Spark with numerous updates. Finally settled on Spark and it has mostly been wonderful to work with. An occasional quirk makes me wonder but still I stay. It is free but that isn’t the criteria which makes them my go-to Mail App.....I would gladly pay $20 or so for it. I do have other Readdle apps and find them all to be outstanding.

Hope this helps. It isn’t perfect; nothing is. But its functionality has won me over with their increased stability and presence of a MAC app.

Post v2.0 Struggle


Prior to version 2.0 my rating was 4 stars. Spark is a solid app with a lot of great features that the native Mail app lacks. The Smart Inbox and notifications are great as well as the Snooze, scheduled delivery, bulk inbox actions, and app extensions. However, I have had a constant struggle with bugginess since the v2.0 release. Their support and dev team have been responsive and released several updates, but too many remain and more keep surfacing with each release. My exchange inboxes have stopped syncing across devices (even though they sync fine in Mail), emails show Subject details for other emails, Apple Watch app will not open anything, and sporadic ‘load message errors’ where messages will not display, among other issues. I experienced another eye opening quirk while traveling in an area with weaker connectivity where I could barely send or receive emails via Spark, while the native Mail app worked just fine. Apparently, your messages make an extra stop on Spark’s servers along the way where certain app features are executed. Privacy concerns aside, somehow the communication between the app and their servers is more prone to connectivity quality issues than the native Mail app. Back to Mail for me.
