What is a global signature?
A global signature will be added to all outgoing emails from your Lab. If your Lab has a custom mail template, you can decide where the signature should be placed in the email, by default the signature will be placed at the bottom.
For the share a separate signature can be configured which will override this one for share emails.
To change the global signature, please navigate to Control > MediaLab > Settings. Please note you must be Administrator to access this feature.
