It would be great if the day of the week (e.g. Monday or Mon) could be displayed in the date picker for snoozing, as this is not always obvious. There is a lot of whitespace next to the date so plenty of room to add the textual dates. When snoozing a lot of emails it would save effort from having to glance at the calendar every time to double check.

It would be great to be able to train AI with company documents, knowledge base and website information to assist with compose and replies. ( see Elephas)

For example you receive 100 emails a day from a client, then instead of seeing 100 you see 1 and similar when you "group by conversation" you can scroll down through them. This way email is not so overwhelming with 800-1000 emails a day. You will maybe 100 of them. This is what Spark has. Adding on behalf of a user.

(posting on behalf of a user) I think the "use custom date" should actually be at the top of that part of the UI (right above the date picker/calendar), rather than the bottom. If a user is just typing in the date they want, then they have to move the mouse a bunch to then get down to the bottom. It's not intuitive that changing that date/time changes the selection at the bottom of the list, since all other parts of that "Snooze" sub-UI are static. I think a "set snooze" button that is more "within" the calendar/clock UI would be more intuitive to "do" the thing that's just been set in the date/time picker.

Since version 3913 an annoying subscription upgrade message shows up above the Schedule button and on a variety of UI menus. By accident you will click the upgrade window multiple times a day. The subscription plan opens in a new window. There is nothing wrong with making a subscription upgrade more accessible. However please add an option to hide Mailbutler's subscription ads. Upodate

It would be great if you could copy, sorry, I mean get inspired by the Superhuman mail app. For example: To hide/remind yourself about an email, you can simply hit CMD + H, and a little popup like macOS's Spotlight shows up, and you type "Tomorrow 8 am" and boom. You're done. Also, please show emails that were snoozed until a specific time at that time. It doesn't help if the email is 20 emails down and just shows up as unread again. Seriously, just sign up for Superhuman and try it. Then bring it to Apple Mail and thank me later. You could easily win over a massive amount of Superhuman users. For me, Superhuman doesn't work because they only support Gmail. Otherwise, I would never look back. Thanks for your consideration. MSM

YES, some time ago, it was possible to insert own HTML-Code as a Signature in Mailbutler. But now it is impossible. Please make it work again!!!

It would be great to add a Zoom link directly while creating a meeting invite

I would like to see external contact synchronization, or as a gross compromise, export. We can't invest in putting contact information in Mailbutler if it creates yet another isolated repository from current Apple, Google, and Microsoft contact records. There is already a large enough market niche trying to address synchronization challenges among those repositories, creating or updating contact information in Mailbutler would create enormous problems for any serious customer.
