Add your signature to Apple Mail.

Mail on Mac

1. 1.Copy the Apple Mail version of your signature, from Email Signature Gen or your install link.
2. 2.In Mail, choose Mail > Settings, then click “Signatures”.
3. 3.Select your account in the left column, then click “+” below the middle column, or pick a signature to replace.
4. 4.Turn off “Always match my default message font”, then paste into the box on the right.
5. 5.Pick it in the “Choose Signature” menu, then close the window.

“Always match my default message font” makes the signature use the font from Mail's Fonts & Colors settings instead of its own, so turn it off before you paste. “Place signature above quoted text” sets where it goes when you reply or forward.

iPhone and iPad

Apple's steps are: open the Settings app, tap Apps, then Mail, then Signature (below Composing), and edit the text. Apple says you can only use text in Mail signatures there, so a signature with a photo and logo belongs on your Mac or in webmail. We don't make a claim about what happens when a formatted signature is pasted on an iPhone.

Questions

Fix a problem

• Email signature logo showing as attachmentThe logo travels inside the message instead of being linked, often in plain text. Link it from a public address and send HTML.
• How to host an image for an email signatureThe image needs a public HTTPS address that doesn't expire: your website, a public cloud link, or a signature host.
