The CAN-SPAM Act of 2003 was passed by Congress as a direct response to the growing number of complaints over spam emails. Congress determined that the US government was showing an increased interest in the regulation of commercial electronic mail nationally, that those who send commercial emails should not mislead recipients over the source or content of them, and that all recipients of such emails have a right to decline them. The act authorizes a US $16,000 penalty per violation for spamming each individual recipient. However, it does not ban spam emailing outright, but imposes laws on using deceptive marketing methods through headings which are "materially false or misleading". In addition there are conditions which email marketers must meet in terms of their format, their content and labeling. As a result, many commercial email marketers within the United States utilize a service or special software to ensure compliance with the act. A variety of older systems exist that do not ensure compliance with the act. To comply with the act's regulation of commercial email, services also typically require users to authenticate their return address and include a valid physical address, provide a one-click unsubscribe feature, and prohibit importing lists of purchased addresses that may not have given valid permission.
To make sure everything is formatting correctly, click Send me a test email to receive a sample message. Toggle to Gmail and check the message. If everything looks good, return to that dialog box and click Send Emails. You’ll now see EMAIL_SENT next to each contact in the Merge Status column of your spreadsheet. If you want to perform another mail merge from that same spreadsheet, remember to delete that text from the Merge Status column of each recipient you want to email again.
