Pros
Pro Free and paid versions
Users who only need to use the basic features of the app have a free version available, though it does limit to only 1 account. There is a paid Mailbird Pro version that does extend functionality and allows for unlimited accounts but it does cost $1.00 a month or $45.00 as a one time fee.
Pro Apps that extend functionality
Mailbird 2.0 supports separate apps that can extend the programs functionality such as Sunrise Calendar, which allows one to add multiple calendars in one view or Evernote which allows for easy not taking and sharing.
Cons
Con Mailbird does not support moving emails between accounts
It's a disaster when you need to transfer all mails into a new account but you can't.

Con Collectss user data
Mailbird does collect some user data such as user email addresses, names and client use. So for those that are security minded the use collection of this information may not be wanted and can not be avoided.
