A survey conducted by the Federal Trade Commission found a high rate of compliance with the Can Spam Act among 100 of the largest Internet marketers. Can Spam established regulations in January 2004 to enable recipients to opt out of e-mail lists.
All the firms surveyed sent an e-mail to FTC monitored e-mail accounts notifying the recipients of their right to opt out of receiving future e-mail communications, in addition to providing a mechanism to opt out of e-mail distribution lists.
Eighty-nine firms complied with three out of three e-mail opt out requests; while 93 firms complied with opt out requests for some e-mail accounts.
To gauge Can Spam compliance, the FTC created three e-mail accounts given out to Internet marketers and opted in to receive offers. After six weeks the FTC staff requested that e-mail communications be stopped.
