Signature Editor

Gmail

Recommended Paste it in. It takes about a minute.

1. Press Copy signature below.
2. In Gmail on the web, open Settings → See all settings → General and scroll to Signature.
3. Click Create new, name it, click inside the editor and paste.
4. Under Signature defaults, pick it for new emails and for replies, and tick "remove the '--' line".
5. Scroll down, click Save Changes, then send yourself a test.

Apple Mail on a Mac

1. Press Copy signature below.
2. In Mail, open Mail → Settings → Signatures.
3. Select your account on the left, press +, and name the signature.
4. Click in the big box on the right and paste (⌘V).
5. Untick Always match my default message font, then choose the signature in the Choose Signature menu at the bottom. Send yourself a test.

On iPhone and iPad, Mail's signature setting is text only, so it can't hold the photo, and a signature set on a Mac doesn't sync to the phone. For a full signature on your phone, use the Gmail or Outlook app.

Outlook

New Outlook, Outlook on the web and Outlook for Mac:

1. Press Copy signature below.
2. Open Settings (the gear) → Accounts → Signatures (on the web: Mail → Compose and reply).
3. Click New signature, name it, click in the editor and paste (Ctrl+V or ⌘V).
4. Set it for New messages and Replies and forwards, then Save. Send yourself a test.

Classic Outlook for Windows: File → Options → Mail → Signatures → New, paste, and set the defaults. Classic Outlook shows the first frame of each animation as a still picture; everything else is identical.

Any other email app

1. Press Copy signature below. It copies the formatted signature, pictures included.
2. Open your app's signature setting and paste into its editor. If the editor turns it into plain text, it only supports text signatures.
3. If the editor asks for a file instead, press Download HTML and choose that file.
4. Send yourself a test.
