@amit I guess this is how most people do it, right on the email client. The only reason I would want to use my text editor, especially if I am using any of my Apple devices, and specifically Ulysses, is its Revision Mode. With English not being my first language, I am very prone to grammar mistakes and such. So for me is a way of helping with that. Also, for example, right now I am composing this reply at my work computer, a Windows PC, and thus, I am using Grammarly on the web to write it and then copy and paste it.

Or at least that is my reasoning and excuse 😁
