Publishers Clearing House (PCH) is one of America’s largest direct marketers and its web property, is now the leader in sweepstakes marketing on the internet. Through value-based magazine and merchandise offers, rich promotions, sweepstakes excitement, and a trusted brand name, PCH is able to attract millions of customers and achieve exponential sales growth year after year.


One of the key ways drives traffic to its website and maintains a relationship with its users is by sending email invitations. These email invitations encourage new visitors and subscribers to enter sweepstakes and review value based magazine subscriptions and merchandise offers online. While their user base is very engaged, they need to be reminded of offerings in order to drive revenue for their program. Otherwise, they may forget to return to the website.

As a result, email is an important revenue driver for their business so they are focused on maximizing deliverability for optimum response. While had near 100 percent deliverability and regularly achieved 20-30 percent click through rates, they wondered if there was some way to increase their response levels, particularly at Hotmail. Hotmail makes up a healthy 17 percent of their list which represents many millions of users. Therefore, even a small bump in response could greatly impact their bottom line.


By becoming a member of Return Path’s Certification Program, would receive inbox placement benefits at 3.5 billion inboxes, including providers like Microsoft, AOL, Yahoo, Gmail, Comcast, and more. They would also receive special privileges that would give them the bump in response that they desired. These privileges include the advantage of no hourly throttling limits. Since sends a large volume of emails every day, the ability to send email without volume limitations gave them the added flexibility to send messages that arrive at the right time.

“The impact of becoming members to the Return Path Certification program was like winning our own sweepstakes! Once accepted, not only did we maintain our good delivery at Hotmail, Yahoo! and all of our key domains, but our click-thru rates improved by 6 percent. That lift resulted in a 20 percent lift in conversion in just two months!”
