Mailman AI

Mailman AI is an email copilot that suggests replies to emails based off context and will generate a reply for you. You can also "describe" edits you want made to the email such as "make it shorter", "make it friendlier", etc. Lastly it has a "professionalize" feature where you can jot down a quick reply and "professionalize" will turn it into a proper email. It works for both Gmail and Outlook.
