Signature Installer App for macOS
If you have a unique signature key then you will want to install your email signature via our installer app. The installation is simple and means you won't have to manually install the signature yourself.
The bonus of using the signature installer app is that it features auto-update functionality and will automatically update your signature in your email client whenever changes are made to it via Email Signature Rescue, preventing the need to re-install.
*Please note that our Signature Installer App is still in beta so we are working on improving it. If you experience any issues, please provide us with detailed feedback via this form.
If you have a html signature file then you can follow the Basic Guide (Copy & Paste).
The Basic Guide is a simple installation which requires opening your email signature in your web browser (excluding Safari), and pasting it into your Apple Mail email client.
If you run into any issues during your HTML email signature installation in Apple Mail on macOS Big Sur, please see the Troubleshooting FAQ before contacting support through your member account.

The app will install your email signature into Apple Mail for you, and automatically update it if changes are made to it by the Email Signature Rescue account holder.

Note: The above video guide will work for Apple Mail on macOS Big Sur.
Follow the Step-by-Step Guide
Open your email signature in Google Chrome or Mozilla Firefox.
If you're logged into your Email Signature Rescue account then you can view your email signature in Full Screen Preview.
DO NOT use Safari to copy your email signature from as there is a bug in Safari that will cause your images to stack vertically.
Now that your email signature is open in a new window, press Command + A to highlight the signature, then press Command + C to copy the signature.
Do not use your mouse to highlight your signature, use the key command. Using your mouse may result in you missing out on some code which will cause issues with formatting.
Open Apple Mail and create a new signature by selecting Mail > Settings...
Click on the Signatures tab. You should then see your email accounts in the left hand side. Select the email account that you would like your email signature to be assigned to, then press the + icon at the bottom to create a new signature.
Give your signature a name and make sure the "Always match my default message font" checkbox is NOT checked. Click into the signature text box and delete all of the contents, then press Command + V to paste your email signature in.
The signature won't display the images in the signature preview window which is completely normal, as it will look fine when we send the email. Test that it has been installed correctly by composing a new email instead.
Close your Settings and compose a new email. You should see that your signature is automatically inserted.
If you find that your signature isn't automatically inserting, you will need to go back into your Preferences and set it as your default email signature.
Congratulations! Your email signature is now installed and ready to use!

I'm experiencing issues with the ESR Signature Installer App
If you do come across any issues when using the app, please get in touch with our friendly support team.
My signature is displaying in Plain Text
Make sure that under your signature preferences, the check box "Always match my default message font" is unchecked. If checked, this will cause your email signature to display in plain text.
Also ensure your preferences are set to compose in Plain Text and not HTML. Make sure that in Mail > Preferences > Composing, you are not set to send in “Plain Text”, but in “Rich Text” instead.
My images are stacking on top of one another
This issue occurs when you copy your signature from Safari due to a bug in their software. As stated above in the guide, make sure you're copying your signature from Google Chrome or Mozilla Firefox to avoid this.
My signature isn't inserting when I compose an email
This can be due to one of two things. The first thing to check is that you selected your signature as your default. If that is correctly selected you need to make sure your signature is attached to your account. In your preferences window make sure your signature is visible when you click on your account and isn't only in All Signatures.
