SPAM-Free Inbox With GoldKey Mail, your inbox can only be reached by invitation or by another secure email account. When email arrives from an unverified source, it is placed in the Junk folder to ensure that the only mail reaching your inbox is mail you want to receive. When you find an important email in the Junk Folder, you can mark the sender address or the entire domain as “not junk.” Once you mark the message, it will be moved to your inbox and future email from that sender will be delivered directly to your inbox. Group Mail, Sharing, & Collaboration Emails can be easily sent to entire groups of contacts using GoldKey Groups. GoldKey provides a way to easily create user groups and invite people to them. These groups are used for securely sharing data, both in GoldKey Vaults and in your inbox. Use Your Own Domain Name Get encrypted email @yourcompany.com. GoldKey Mail makes it easy to set up email accounts using your own private domain.
