My images are stacked under one another instead of side-by-side

This issue occurs when copying your email signature from Safari. If you're experiencing this, you will need to open your email signature's HTML file in Google Chrome or Mozilla Firefox (or be logged into your Email Signature Rescue account using Chrome or Firefox if copying from Fullscreen Preview) then copy the signature from there.


My email signature doesn't look right when I paste it or send an email

More than likely, you have used your mouse to highlight the html email signature file in the browser. Don't use your mouse, only use Cmd + A (hold the Cmd key and press A at the same time) to select all of your email signature. If you use your mouse, you may miss out on some of the vital code needed to make your signature work correctly.

Another cause to this could be that you've used Safari to copy your email signature from and not Google Chrome or Mozilla Firefox. Using Safari will cause formatting issues. To resolve this, install Google Chrome or Mozilla Firefox from our Before You Start screen and copy your signature from one of these browsers instead.


I am composing an email and I can't click on any links or social media icons

In compose mode, most email programs won't allow you to use the links in your email signature. Check to see if your email signature has been installed correctly by sending a test email to yourself instead. The links and social media icons should work when you receive the email.
