Troubleshooting: Email signature is too long message - Character limit restriction

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?
