The email template received by your recipients will inherit the branding preferences associated with the account. Once you’ve created a brand, sorted colour schemes and uploaded a logo, the email template will also be updated. This feature is only available to Business Pro and Enterprise plans. For more on branding including instructions on creating branding, read here.
The sender card is an element shown to customers in the email template and on the PleaseSign website used to identify the sender of the document. The fields shown in this card are automatically inherited by the sender of the document, or otherwise overridden if a brand is in use.
