How to remove [Netlify] from subject?

Thanks for that feedback, Tom. Our Support keep requesting it for you and the others who want it, but it is a hard thing to prioritize since it doesn’t really drive any revenue and it is a lot of work (we’ve learned that creating the option is not sufficient; you have to write the docs, and create the UI for it, and those things take a fair amount of time and effort away from more useful work).

We’ll still post here if there ever does become such an option.
