Did you know the US government, in an effort to squash non-solicited marketing emails, says you need “a visible and operable unsubscribe mechanism” present in all emails? Fear not! Zenfolio is compliant with this policy: the unsubscribe option is at the footer of all the emails that you send to your customers, automated or otherwise.
When you get visitor information from your contact page, visitor sign-in, registration, or from a placed order, this information is added to your contact list and that person is now subscribed to your emails. You can feel confident marketing to your list of clients and visitors, knowing you are CAN-SPAM compliant.
