I really wanted to love Postbox. The Evernote and Todoist integrations had me drooling. The reality is however that the program is very buggy. Folders disappear (or don't appear at all), messages don't get copied into the sent folder regularly, sent folder disappears completely, program freezes up and the list goes on. The kicker is that they won't offer you any support, even for a bug, unless you pay a fee to open a ticket. Isn't that a reverse incentive? So they collect cash to help you resolve a bug or issue with the product they sold you.. hmmm. Too bad, the were on to something but the execution and lack of support kills it. Don't waste your money.

I don't like the way it works with gmail labels. If you delete an email from a folder where that email has two labels, it only removes it from that one folder and does not delete the email from the other folder. I don't want to have to delete it twice or hunt it down in the "all mail" folder somewhere. Gmail would delete it no matter how many labels it has. Since I'm a heavy label user, this won't work for me.

Postbox worked fine but I had hard drive issues. So I reinstalled it - nothing but problems and I can't get my local folders back even though I saved them first.

Still no support for Spamsieve in v6? I'll be holding off renewing my licence for a while longer then.

Pity, because I'm getting a awful weary of Apple Mail.

watch for the 'how to use' emails, use v and t for great functionality. I'm blown away by how they've really generated email productivity beyond what I've seen elsewhere, intending on purchasing when trial period finishes.

Just downloaded version 6.1.12 of Postbox. It is beautiful, smart and powerful as advertised. The new version loaded easily, didn't lose anything, and presented me with great new UX and functionality. Fixed a whole lot of nagging issues for me too! Thanks for building a great team, dedicated to superior product design and delivery.

I have been using PostBox for many years now. Love the organization of it and the ability to manage several email addresses. I recently had an issue where I lost all of my folders and the emails in them. At first I thought it was a PB issue. I must say that Tech Support was very helpful and helped isolate the problem. It was my least favorite email host-AOL, They changed their platform which made old folders obsolete and unusable (although the data was still on their server). Finally, redid the folders on AOL and now everything works. I mention this in case anyone else finds the same's AOL. PostBox staff were great, helpful and the product is still my favorite. Highly recommend it.

Downloaded a trial version and am loving everything about Postbox. I had been using Th____rd, which was buggy and missing some important features--all that Postbox has and does well. Glad to finally find a desktop email client and that I can live and grow with. Will be pressing the Buy button shortly.

I switched from Apple mail, and the difference is HUGE! Postbox has so many more features. Apple mail was full of bugs, with weird things happening. I ended up with 15,000 messages in "Recovered messages". Apple has not explained to Dr. Google what those are! Now, using my email is a delight, and so much quicker. I love the responses feature. Postbox also has top-notch support, as I had questions. HIGHLY RECOMMENDED!

This version breaks dark mode on Mojave, otherwise a great email client.

OK, I just figured this out. The description of the update mentions a new "Theme" button to alternate between light and dark modes. You have to customize the toolbar and add the button. In the window that opens showing the available buttons, you have to scroll to the bottom of the window or you won't even see the button. They should've added it by default to the toolbar.
