Add a signature in Apple Mail.
Mail on a Mac keeps a signature per account. Make it here, then paste it in with one checkbox turned off first.
In Mail on a Mac: Mail, Settings, Signatures. Select the account on the left, click the add button, untick “Always match my default message font”, and paste into the right-hand column. Then pick it from Choose Signature.
Put your name in and the signature appears here.
Nothing is stored. No images and no web fonts unless you choose them, so it renders the same in every mail client.
Into Apple Mail, in 6 steps.
