Gmail limits a signature to 10,000 characters. The builder blocks the copy if yours is over.

1. The Gmail app can only set a plain-text mobile signature. Instead, turn the mobile signature OFF so the app uses the web signature for Google accounts.
2. In the Gmail app: Menu → Settings → your account → Mobile Signature → turn it off.
3. Set the signature on Gmail web (above); it will be used when you send from the app.

No paste needed on the phone. If your account is not a Google account, use the send-to-phone page instead.

1. Click "Copy formatted signature" below.
2. Open Settings → Accounts → Signatures (new Outlook) or Settings → Mail → Compose and reply (outlook.com).
3. Choose "New signature", paste with Ctrl/Cmd+V, and choose your defaults.
4. Save.

1. Download the .htm file below.
2. Press Win+R, type %APPDATA%\Microsoft\Signatures and press Enter.
3. Copy the downloaded .htm into that folder, then restart Outlook.
4. File → Options → Mail → Signatures and pick it. (Or paste the copied signature there.)

Outlook 2016 and 2019 show only the first frame of each GIF, which is why frame 1 is always complete. Microsoft 365 builds animate.

2. Outlook → Settings → Signatures → +.
3. Paste into the editor, name it, and choose your defaults.

1. Open the send-to-phone page on your phone (QR code or link below).

Formatting support in the mobile Outlook signature box varies by version. Recent Microsoft 365 builds can sync signatures from the web instead.

1. Mail → Settings → Signatures → + to create a placeholder signature, and note its name.
2. Quit Mail completely.
3. Download the .mailsignature file below and replace the placeholder file in ~/Library/Mail/V10/MailData/Signatures/ (the placeholder is the newest file there; V-number varies).
4. Right-click the new file → Get Info → tick "Locked" so Mail does not reformat it, then reopen Mail.

Pasting also works for simple designs. The file route keeps everything intact.

1. Open the send-to-phone page on your phone (QR code or link below) and tap "Copy signature".
2. Settings → Apps → Mail → Signature (older iOS: Settings → Mail → Signature), and paste.
