Cons
Con Drag & drop is impossible
Drag & dropping folders and emails between accounts are not possible.
Con Poor import/export of contacts
You can only import your contacts data via CSV, which isn't the most popular choice. Much more convenient ways to do so exist. Even the older Windows Life Mail program is more flexible when it comes to contacts and offers such features as duplicate checks.
Con Collects 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.
Con Only available for Windows
Con It's all about cash - support, new licenses policy, bugs. Not worth buying.
Two programmers coding - this means every release is full of bugs sometimes making this app unusable. Dev version is testing via community.
