Troubleshooting: Email signature is too long message - Character limit restriction
If you're receiving an error message saying your email signature is too long, then you are using the web extension incorrectly.
The web extension replaces the need for using your mail client's settings. So if you are using Gmail, you should not be attempting to install your email signature in Gmail's settings once your email signature has been installed in the web extension. Our web extension will automatically add your email signature to any emails within that mail client.
Troubleshooting: Where do I find my email signature key?
- If you are an Email Signature Rescue member and are logged into your account, you can access your signature key directly from your Dashboard. Simply click the Key button then highlight and copy the key code.
- If you have been emailed your email signature key, go to the email and copy the key code.
Troubleshooting: I don't have an email signature key
If you don't have an email signature key, but have an email signature file, you can still install your email signature into the web extension using your signatures HTML code.
If you don't have an email signature key, then you can also install your email signature by using the HTML code. Copy your HTML code then open the web extension, click Advanced Settings then click Enter Custom HTML Code, paste your code and click Save HTML.
If you don't have an email signature HTML file, consider joining Email Signature Rescue now and get creating! We offer over 20 professionally designed and tested email signature templates, tools and features to create and manage your email signatures online and a whole lot more.
What happens once I have installed my signature?
