WiseStamp is an email signature generator that helps you create professional looking email signatures for all your accounts. The WiseStamp web application is available in Shift for any Shift Advanced user.
Recently we have found that the functionality provided in the Wisestamp app is not the same as in the extension.
If you a fan of the WiseStamp extension, please let our team know in this feature request survey so we can prioritize it for an upcoming release.
In the meantime, there is a workaround you can try. Just copying and pasting the email signature from WiseStamp into your email's signature will give you your desired signature.
