Email triage solution that actions and handles emails based on preferences
Superhuman could be improved by being made available across a broader range of devices including Android and Windows PCs. Superhuman is also a phone app, which is available only on DiOS right now. Because it's not available on Android, you have to use Gmail for your phone, and use Superhuman for your desktop. The search feature could be improved. Currently, Gmail search is a lot more robust because you can filter results based on your requirements. Superhuman does not offer this way of searching which can make emails difficult to find.

Our customers are able to use this groupware solution to connect to Active Directory and OpenLDAP, although Postgres support would be an improvement.
Zarafa has several very valuable features, among them a very good Outlook-like web interface. Furthermore, ZPush for talking between ActiveSync and mobile devices is a valuable asset. In addition, one is able to connect via Outlook and the exchange protocol to Zarafa. This makes Zarafa a free, and working, alternative to Microsoft Exchange.

"It is a productivity-driven email software that is fast, increases your productivity, and cuts down the time you spend compared to traditional email software."

"This makes Zarafa a free, and working, alternative to Microsoft Exchange."
 

Cons

"It can have a few more integrations. As far as I know, it is being integrated with Salesforce."
"Superhuman could be improved by being made available across a broader range of devices including Android and Windows PCs."
"Not really, although the Zarafa-index component was using a lot of memory and disk I/O bandwith."
