Trust. Teamwork. True collaboration. These are more than feel-good buzzwords for us. These are the concepts that inform both how we work with each other and our clients. Nothing exemplifies this better than our four-plus year relationship with T-Mobile.

The relationship started with a singular focus on one of our specialties: customer retention and loyalty. These efforts included high-impact mail and highly targeted e-mail campaigns for a variety of offerings — new phones like the T-Mobile G1 with Google and Sidekick, new plans like myFaves and so much more.

And, as always, everything was highly personalized with multiple versions to ensure the highest possible response rates.

"This work," said Ryan Butz, T-Mobile Director of Customer Marketing and Advocacy, "delivered better results than we've ever seen before for similar campaigns."

Word spread quickly at T-Mobile. So did the size and scope of the assignments.

With a stream of successes under our belt, T-Mobile asked us to take a closer look at its customer retention program. Together, we transformed a quarterly listing of deals into SCOOP, an award-winning, cross-platform monthly conversation with customers.

Our work featured the entirety of the SCOOP brand, including SCOOP's unique name, tag line, look and feel, tone and perspective to ensure that absolutely everything was focused on customer benefits, not simply product and service attributes. We evolved a basic buck slip into an impactful bill insert, e-mail, mobile and website.

The result: A powerful communications tool that continues to engage customers with what matters most to them.

With SCOOP gaining momentum, T-Mobile engaged us to help establish the company as the greenest wireless carrier in the industry.

Together, we created the Mobilize with T-Mobile program. This award-winning cause-related marketing campaign was built around T-Mobile's ongoing partnership with the Arbor Day Foundation and its pledge to plant 1 million trees.

The program was among the leading green efforts in the industry, and included a number of strategically complementary pieces, including a deep, immersive website, a highly successful Facebook application, a partnership with Facebook Causes, as well as e-mail, mobile and other outreach efforts.

To date, over 1 million trees have been planted with a 62% increase in Paperless Billing accounts. Current ROI for the program is at 236%.

One of the earlier programs we worked on for T-Mobile was designed to right fit their customer's plans with their calling patterns. The program helped customers find more value-based plans for the way they used their phones.

In a lot of ways, that describes our partnership with T-Mobile. As we grew the account from a team of four to 35, as our Seattle office expanded into a bustling hub of in-person collaboration, the right fit made it all work so well, so seamlessly.
