If you are a team leader on the Premium, Enterprise or Enterprise + Phone plan, you can share your templates with your team members. Through the Template Manager pages in Gmail or Outlook, you can "copy" or "move" the templates to your team categories.
You can access the Template Manager in Gmail by opening a new compose window. From there, select Templates > All Templates. At the bottom of your templates, you will have an option to "copy" or "move" the template.
In Outlook, you can access this page by clicking the Templates section of the Yesware ribbon.
