According to the CAN-SPAM Act, it is mandatory by law to tell recipients where you're located. SendX makes sure your emails are compliant to CAN-SPAM and makes it mandatory to enter your correct postal address in Settings.
The address must be a valid physical postal address. It can be your current street address, a post office box you've registered with the U.S. Postal Service, or a private mailbox you've registered with a commercial mail receiving agency established under Postal Service regulations.
SendX makes it easy for you to comply with the CAN-SPAM policies, by having a default Unsubscribe Message (which can be edited if you desire) all set to display with your emails. This message will contain your Address, Email, and a link to Unsubscribe.
