SafeShare is allowing the administrator to send emails to its customers from Backend > Customers > Mass Email.
You can choose groups to which the email will be addressed.
If no group will be selected, the email will be sent to the entire customers list.
On the other hand, if a customer, or potential customer wants to get in touch with the administrator he can do it from the Contact page located in the frontend. All these messages can be read by the admin from Backend > Misc > Contact messages
