Installing your email signature

You should have been provided with a signature key, or you have an Email Signature Rescue account where you can access your key from. Find the signature key for the signature you want to install, then copy it.

Open Outlook and compose a new email, then select the Message tab at the top if it isn't already open. From the Add-Ins menu ribbon, you should see the pink logo for Email Signature Rescue. Select this to open the Add-In.

Wait a moment for the Add-In to load, then click the pink Add Signature button at the bottom of the Add-In.

Insert your copied signature key and click Verify Signature Key at the bottom.

Give your signature a name and select a color theme so that you can identify it – this is helpful if you're installing multiple email signatures.

Check the options for Add to new emails, reply emails, and forwarded emails as desired.

Click Install Signature.

Your email signature has now been installed into the Email Signature Rescue Outlook Add-In. Click the email signature to add it your emails.
