Setup WiseStamp without being a Super Admin of a Google domain
If your company is using Google Workspace (G Suite), only the Super Admin of the Google domain can set up the WiseStamp account for your company. Send him this link to get started.
Tip: The domain admin is probably the founder, the company IT person, or CTO.
Once the account is started he can then give someone else (you!) access to become a WiseStamp account administrator. This gives you control over the signature design and settings. Just have a current WiseStamp account admin go to the Manage Users tab, search for your name in the user list, and click edit to enable Admin access for WiseStamp.
