HTML Email Signature - Mail
HTML Email Signature - Mail creates an Apple Mail signature using valid HTML supplied by the user, with a preview and markup warnings.
Pick when Apple Mail users already have prepared signature HTML.
A narrow install-and-preview workflow helps preserve an existing design without rebuilding it in rich text.
Keep in mind: It is not a visual HTML designer. Appearance depends on your markup, image hosting and recipient mail clients, and requires Apple Mail to be installed.
