Autograph is a native Mac app that designs professional email signatures and installs them into Apple Mail in one click, assigned to the right accounts. When a macOS update or an iCloud sync wipes a signature, Autograph puts it back automatically.
Professionals and teams pick a template arranged by profession (real estate, law and finance, consulting, sales and more), apply their branding with colours, fonts, logo, photo and banner, and check how it looks on a phone. Photos, logos and banners are hosted, so they render in Gmail and Outlook instead of arriving as attachments, and a QR code sets up the same signature on iPhone and iPad.
Autograph is a one-time purchase with no subscription and no account, with licences for 2 to 25 Macs. A free tier covers installing, account assignment and iPhone setup.
