works like an old email client, downloading the message and saving in folders. It doesn't work syncing directly online with gmail labels.

There is NO Spark Version for Windows. That's why Thunderbird is the Best Alternative IMO.

Spark is much more clear and tidy than Outlook. I am waiting so hard for Spark to come out for Windows because Outlook is driving me crazy sometimes.

its just totally out-dated. configuration a horror. screen-display on small displays (laptops) almost unusable (space for email-text max 10-20%). and since beginning problems with imap (every some weeks big imap-problems).

Comments about Mailspring as a Alternative to Spark Mail
Almost everyone thinks Mailspring is a great Spark Mail alternative.
Thomas Klinger
I tested it, generally it is ok, but it sometimes does not show new arrivals at the top of the list, even though the counter increases. However, good mail client, which does not need any clumsy registrations somewhere.

As far as my usage history, the best alternative for spark mail is Mailspring in terms of UI and UX. Though it lacks some features I use Mailspring as my daily driver.

It's the most similar, with the features most inline. It even looks the same in appearance, and all the menus and shortcut keys match.

Is not a free version of an email client. The fact that you have to pay for more than one email account makes it useless.

Comments about BlueMail as a Alternative to Spark Mail
Most users think BlueMail is a great Spark Mail alternative.
byronhawkins
BlueMail is built as an entire Chrome browser instance, using a separate OS process for every message window, making it massively heavy on CPU and memory usage. Normally I had to wait more than a minute for each message to display. It was always at least half an hour late to notify new messages. A software development team with even minimal skills would never build an app so poorly. The design is crippled from top to bottom. I recommend avoiding BlueMail as if it were malware.
