Autograph is a native macOS app that helps people create polished email signatures for Apple Mail without dealing with HTML or manual copy-and-paste. Users can start with professionally designed templates or build a custom layout, then personalize it with a photo, company logo, contact details, promotional banners, and social links. Font and color controls allow individual lines to be styled, and multiple email addresses, phone numbers, and addresses can be arranged in one signature.

Once a design is ready, Autograph installs it directly into Apple Mail and assigns it to the appropriate account. The app is designed to help signatures retain their appearance across inboxes, including Outlook and Gmail, using email-compatible layouts and hosted images. Signatures can sync across Macs through iCloud, with guided setup for iPhone and iPad.

Autograph runs on the Mac without requiring an account or cloud-based signature service. It is free to try, with a one-time $39 payment to unlock Pro, no subscription, and support for one or two Macs running macOS 14 or later.
