- For those that experienced crashes, we've solved that error

- We fixed the failing Tracking when sending plain text emails by switching to rich text before sending
- We fixed a rare bug that could accidentally cause messages to be marked as read
- Now we show beta track option also on production version, so that it's easier to go back to the release track

MailButler 2205
- We think some Halloween spook got into our dark mode, so we fixed the wrong appearance when disabling Apple Mail's "Use dark backgrounds for messages" preference
- Were you missing email subjects in your notifications? We've put it back on the dashboard and notifications for Catalina users.
- We've got Send and Send Later back up and running so it no longer crashes your computer and interrupts your workflow

- Indicators are now also in the message header, next to Date Received. Now you can see at a glance if notes, tasks, or follow-ups were added to the message. It's still shown even when the Context Sidebar is collapsed.

MailButler 2024

MailButler 1704
- First impressions are incredibly important, so we've made our communication even more clear should you ever come across a login or registration error
