Apple Mail Signature

A signature Apple Mail actually respects.

Apple Mail uses WebKit — one of the most capable email rendering engines in use. That means your signature can have photos, colors, custom fonts, and multi-column layouts without breaking. SignatureGen ships HTML that takes full advantage of Apple Mail while staying compatible with Gmail, Outlook, and Yahoo for your other recipients.

Apple Mail signature questions

Everything a new user wants to know before they trust a tool with their name and inbox. If we missed one, open an issue on GitHub.

How do I add a signature to Apple Mail on macOS?

Open Mail → Settings → Signatures. Select an account, click +, then paste your copied signature into the preview pane. Uncheck "Always match my default message font" to preserve custom fonts and colors.

How do I add a signature to Apple Mail on iPhone?

Open Settings → Mail → Signature. You can paste rich text, but for full HTML, set up your signature on macOS first and enable iCloud Mail sync — your signature carries over automatically.

Does Apple Mail support HTML signatures?

Yes, Apple Mail fully supports HTML signatures, including images, colors, and custom fonts. It uses WebKit to render — one of the most capable email rendering engines.

Why does my Apple Mail signature lose formatting?

In Mail settings, make sure "Always match my default message font" is unchecked. When that is on, Mail strips your custom colors and fonts. Toggle it off and your signature will render correctly.

Can I use different signatures for different accounts?

Yes. Apple Mail lets you set a separate signature per account. Create one with SignatureGen, paste into the appropriate account row in Mail → Settings → Signatures.
