Keep it on the site, and keep it short
People are already on your page. Build the form, set the colors and type, and place it there. They do not leave for a generic form in someone else’s layout.
Three fields cover most sites. Add a subject choice when sales and support share one form and need different routes. Add a file field when people send screenshots. Wait to add anything else until real messages show you a question you keep asking back.
