How to Add an HTML Signature in Apple Mail
Apple Mail does not offer an HTML editor, but pasting a ready-made signature works if you create a placeholder first. Create yours with the free email signature generator and click Copy signature.
On Mac (macOS Mail)
- Open Mail → Settings → Signatures.
- Select your account, click + and type any placeholder text (e.g. “sig”).
- Click into the preview area, select the placeholder text, and paste your copied signature over it.
- Untick “Always match my default message font” so the signature keeps its own styling.
- Set “Choose signature” to your new signature and close Settings. Compose a test email to verify.
On iPhone / iPad
- Email the signature to yourself and open it in Mail on the iPhone.
- Long-press to select the signature, Copy.
- Go to Settings → Mail → Signature, paste — then shake the phone and tap Undo if iOS strips the formatting (this restores it).
Photo missing? Images must come from a public URL. If you used a local file path it will not travel with the email — host the image on your website and use that URL in the generator.
