Their support is horrible. Beginning the third week of plsatitudes and apologies, but NO FIX to a basic, fundamental requirement to sync my calendar.

Mailbird is great at consolidating all of your emails into one application. It's super simple to set up a new account.

But there is no way to contact by phone. All I get is a computer generated stupid answer to my questions.

Mailbird offers a once-off licence purchase which a great plus for such a powerful email application.

I am from the old school and when I had a registration problem I had trouble getting someone to respond.

What I enjoy most about Postbox is the ability for me to customize it to my needs. I also enjoy the new features that allow me to quickly form communications and sort my incoming emails.

Filters, rules, folders, quick commands - excellent choices to help speed along message handling. Also excellent capabilities with encryption and signatures.

Notifications are still somewhat ugly, and there is no more specific configuration about that (disable notifications for an account or certain emails, for example).

Reliable, stable Software, fast, and gets continuously improved.

When I contacted the support, I was asked to paid 8$ to get assistance. I bought a lifetime licence and now I am stuck with a broken software.

I like the theme option with the software and the ability to organize accounts groups as well as folders etc easily on the fly.
