How to install your email signature in Apple Mail
Apple Mail supports rich signatures, but it has one default that fights custom formatting: Always match my default message font. Turn that off before you paste, or Mail overwrites your font and color choices with its own. The rest of the install takes under a minute.

Open the generatorCopy your signature
Open your personal signature link and click Copy signature.
Open Mail settings
In Apple Mail, go to Mail, Settings (Preferences on older macOS), then click the Signatures tab.

Uncheck Always match my default message font. This is the setting most likely to strip your signature's colors and fonts if left on.
Add a new signature
Select your account in the left column, click the plus button to add a signature, then click into the signature box and paste (Cmd+V).
Set it as default
Use the Choose Signature dropdown for your account to select the new signature for new messages.
Common questions
Apple Mail applies its own default font over pasted signatures unless Always match my default message font is unchecked in Mail, Settings, Signatures. Uncheck it, then paste again.
Yes. Signatures are set per account in the same Signatures tab, so repeat the steps for each account that needs one.
Apple Mail on iPhone has its own signature setting under iOS Settings, not the Mac app. See the iPhone Mail install guide for that flow.
