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 customisation and the way it bubbles important emails to the top while filtering out the noise. Inbox intimidation is now a thing of the past.

Doesn’t auto update emails.

I really like spark it’s my default mail app for my mac and phone, I had to give one star in hope for the developers to see this.
What use is the widget when new emails don’t show up unless I open the app and wait for a couple of seconds? The notification badge shows on the icon, but when I open the app it takes a moment or two to show the new emails, or I can swipe down to update the list.
The result is the new emails aren’t showing in the widget unless I launch the app, wait until the new emails load, close the app without opening the emails.
I hope it gets fixed, spark is still my favorite mail app.
