How to install a html email signature in Gmail on Safari

Download or save your HTML email signature file to your computer, then open it in your web browser.

With the email signature open in your web browser, press Cmd + A to highlight the signature, then press Cmd + C to copy the signature.

Important: Do not use your mouse to select the area, only use Ctrl + A as you may miss out on grabbing some of the code.

Login to your Gmail account and navigate to the Settings cog icon at the top right of your screen, then select Settings from the list, and select See All Settings.

Scroll down the page until you see your Signature settings, then click Create New and enter a new name for your email signature. Click inside the text field to the right of your signature name, then press Ctrl  + V (⌘ + V for Mac) to paste your copied email signature.

Under Signature Defaults, select your new signature for New Emails Use, and On Reply/Forward Use.

Scroll down and hit Save Changes, then compose a new email and your email signature will automatically insert.

Download and install our macOS Signature Installer App.

Run the app once, then you can Quit using the icon at the bottom left of the app.

Open Safari and from your menu bar select Safari, then Preferences. Go to the Extensions tab and enable Email Signature Rescue.

Once enabled, an ESR icon will appear on your Safari toolbar to the left of your URL address bar. Click the extension icon to expand the extension, then complete the steps to install your email signature.

Select Gmail from the first drop down box. Enter the email address that you'd like the email signature to apply to. And finally, insert your signature key and click Install.

Your email signature will now automatically insert when composing an email within Gmail in Safari.
