Ranked in these QuestionsQuestion Ranking
Pro Clean interface
Airmail has a very clean and modern interface. On the left side of the screen are the folders (inbox, starred, draft, sent, snooze, trash) and on the right side the email threads for the folder currently being viewed.
Pro Multiple ways of sorting emails
There are multiple ways to sort emails with Airmail. You can sort by unread, starred, attachments, conversations, dates, and many more criteria. You can even combine different criteria together.
Using these filters makes it extremely easy to quickly find any email you are looking for.
Pro Automatically syncs settings between devices
If you are using Airmail in different devices (either MacOS or iOS), you can automatically sync settings through iCloud.
Pro Extremely customizable
Instead of forcing the user to work with their email the way Airmail developers would want, it allows the user to customize and make the email client work the way they want because of the sheer flexibility of the application.
There's a lot of settings available in Airmail with which you can customize almost every aspect and functionality of the app. In fact, it's very easy to get lost in them and spend a lot of time tweaking and customizing everything to your liking.
Pro Always keep the inbox clean
Airmail allows users to snooze an email until a defined moment (a few hours later, tomorrow, next weekend, next week, etc.), allowing you to process every email immediately and to always keep the inbox clean.
Pro Supports Gmail shortcuts
Pro Fast and easy setup process
Even though there's a huge amount of settings available, it's quite easy to get used to each of them and the setup process is very fast and easy.
Pro Consistent interface between devices
Airmail is available for both iOS and Mac, for people who use Apple's mobile devices. And the interface between both platforms is quite consistent, making it easy to seamlessly jump between one and another.
Pro Supports trackpad gestures
Airmail is able to use trackpad gestures for achieving and deleting mail items.
Pro Support for VIP folders
VIP folders are for particular senders which you always want to read even when you are ignoring email. The way it works is that you add different senders as VIPs and emails from those senders will always be surfaced on top of everything else.
Pro Integrates with multiple third-party services
Airmail can integrate with multiple Cloud services for syncing, creating backups, adding tasks and more. Some of these services include Dropbox, Box, Fantastical, 2DO, Todoist, Wunderlist etc.
Pro Free and open source
Licensed under GPL v3 with code available on GitHub.
Pro Plug-in support
Pro Sophisticated address book
Each contact can have their e-mail address, phone number, location, photos and associated URLs added to them. You can then group contacts and address your mails to the group instead of having to enter each person separately. Additionally, you can import vCards and CSV files as contact information. And, it has LDAP connectors.
Roundcube is available in over 70 languages.

Roundcube supports attaching files simply by dragging and dropping them in.
Pro Access control support

Pro Multiple identities
You receive mail from multiple sources in one account.

You can enable/disable spellcheck by changing "enable_spellcheck" in main.inc.php file.
Pro Good documentation
You have access to the documentation for APIs as well plugins development.
Pro Built-in caching
Roundcube caches messages to allow quicker access to your mailbox and to alleviate the strain put on the server. You can turn off caching (change 'enable_caching' property in your config/main.inc.php file) if you need messages to appear instantly.
Has auto-refresh functionality for email boxes.
There are many issues/bugs with different accounts, including Gmail and iCloud.
Con Copying/moving mails unreliable
Doesn't work most of the time even though the operation is reported as successful. Even has lost emails when moving. Support was not too much use either.
Con Inability to turn off auto-creation of labels
Version 3 does not allow it while version 2 did.
Con Serious sync problems
On some IMAP accounts, there are a number of serious sync problems, which otherwise work fine with Apple Mail.
Con iOS app requires a subscription to enable incoming mail notifications
The iOS app now requires a subscription to enable incoming mail notifications. This makes the iOS app very unattractive and there's little point installing the Mac desktop client for users who want to sync accounts between devices.
Con Rather expensive
Con Not free
Paid version only.
Con UI is a little busy
Con Has the "slow typing" bug
When composing an email, Airmail can respond very slowly to keystrokes. Customer service refuses to acknowledge this problem, responding that it's "not real" - which is a very odd response, to simply refuse to acknowledge the customer's experience.
Not easy to create your own themes.
Con Moblie Use
Does not translate to mobile use very well
Con For search there is no reverse index
This means it is very slow.
Unfortunately, all interfaces of roundcube look very old. I hope there will be a progress soon, Google Mail and Outlook Webmail should be the role models here. But also Yahoo mail offers an intuitive design.
If this open source software should survive, it must be completely renewed and bring up to new standards.
Con Extremely clunky unintuitive interface
For example the mouse cursor may start getting stuck and lag.
Con Search option are limited
You can only search for one item at a time instead of multiple search terms, which makes it difficult to go through large amounts of emails.
Con You can't make multiple accounts
It is not possible to make more then one account.
