A beautiful blend between Mac Mail and GMAIL

I switched from Thunderbird to Spark, currently using it with 9 different e-mail accounts (8 imap and 1 gmail).
The interface is very similar with Mac Mail, but it also has a lot of functionality features, such as:

- pinned mails
- smart inbox - very handy when you use ‘important’ and ‘less important’ accounts, as you can select the ones you want to view in your smart inbox
- more swipe gestures (although i still use 2, with long swipes I sometimes delete my mail accidentally)
- snooze mail
- color badges for different accounts
- quick replys with icons (Thanks, Like, Love, etc.)
- mail categories (newsletters, notifications, seen, etc.)
- integrated services - such as OS X Reminder
- a beautiful and loveable UI
- app available on iphone, ipad, apple watch, although i still prefer the standard mail app on my iphone

It also has some bugs, that should be fixed:

- notifications keep popping up from accounts where notifications are disabled
- sent mail appears sometimes in the wrong account (i.e. I start composing from gmail account, then I select a different one in the “From” tab, after I send the mail, itt will still appear in the Gmail Sent Box, although physically it is not there)
- search is a bit slow

All in all I LOVE IT! The best mail client I have ever used on my Mac.

Updated review: Since you MUST log into your Spark account - i uninstalled it

Update: All features that I mentioned below are still valid, but for me, forcing to 'backup' all my data to Spark is a no-go.
Deleted the app.

I am using Spark since about one year with 4 accounts and can say the following:
- Very stable app. No slow-down or crash encoutered.
- Good design - but that is subject to personal preference.
- Good imap integration.
- Good pop3 integration.
- Often updates. High development effort.
There are few points which I’d like to mention in order to make Spark even better:
- Make ‚reply‘, ‚reply to all‘ and ‚forward‘ action buttons available for direct selection. Mouse and touch users would be greatefull not to go into menus / selections in order to ‚reply all‘ or ‚forward‘ an email. A good position would be the top bar where the ‚delete‘ button is located along others.
- Option to display just single emails. Currently whether you like it or not, the conversation chain is listed below.
Thanks very much for makeing this great app free!


Ok app

I used the app several months. It's a beautiful and clean application. But it's still need to work on it and that's why I uninstalled it. The first problem was with attached files that were downloading very slowly. You receive the email and then wait for the attached files to appear, too. The second problem was with the printing of forwarded emails. If you received an email as forward from someone else, the forwarded portion did not appear in print.
