    Troubleshooting: FAQ

    Troubleshooting: FAQ

    If you have tried our Step-by-Step Instructions or Browser Extension instructions for installing your email signature in Google Inbox and you run into any issues, please read through this troubleshooting guide before contacting Support for further help.

    I get an error saying my email signature is too long.

    Gmail and Google Inbox have a character limit on email signatures. If your email signature is over 10,000 characters, it won't save if you directly paste it into Google Inbox's signature settings. You will need to follow the instructions for using our free web browser extension instead. See our "Before You Start" section.

    If I use the browser extension, will my email signature work with the Google Inbox iPhone/iPad app?

    No. The way the browser extension works is that it injects the HTML from your email signature directly into the browser page, it does not save it to Google Inbox's settings. In order for your email signature to work in both the desktop and iPhone/iPad app versions of Google Inbox, you will need to reduce your email signature to approximately 10,000 characters and install it directly into Google Inbox's signature settings.

    If you're a member of Email Signature Rescue, there is a "Count Characters" button located in the red side menu, while editing your signature. Use this button while creating your signature to count the characters. If you have any issues creating an email signature that will fit into Google Inbox's settings, please contact Support through your member account and we can assist you.

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

    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 Ctrl + A (hold the Ctrl button 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.

    I've installed my email signature but it isn't showing when I compose a new email

    Google Inbox doesn't display your email signature in composition mode. When you hit send, your email signature will be added to the end of your email and sent. You can check this in your Sent box.
