When Lathrop GPM discovered that none of its competitors were actively marketing to closely held businesses, they enlisted Greentarget to help mine this untapped client segment
Challenge
In 2024, the Business Development team at national law firm Lathrop GPM discovered that nearly one-third of the firm’s top 250 clients were closely held businesses (CHBs)—and none of its competitors seemed to have a focused marketing strategy directed at this audience.
Unfortunately, neither did Lathrop GPM. Despite key practices areas serving this clientele—including Business Transactions, Litigation and Private Client Services—the firm lacked targeted thought leadership materials to support outreach. Word-of-mouth and general marketing efforts, then, remained the primary channel through which CHB owners discovered Lathrop GPM.
To increase both internal and external visibility of the firm’s strong track record with CHBs, the firm turned to Greentarget for help.
Approach
Lathrop GPM kicked off the initiative by revamping the firm’s CHB-focused webpage and creating a “Closely Held Business Institute” logo to unify branding across thought leadership, products and outreach. They also developed a tailored email list representing 80% of the firm’s largest CHB clients, prospects and referral sources.
From there, the firm partnered with Greentarget’s Content & Editorial team to launch the CHB Institute newsletter in August 2024, with three subsequent editions released in 2025. Each newsletter features a thought leadership article by Lathrop GPM attorneys, a “success spotlight” showcasing a firm win on behalf of CHBs, a curated list of relevant news stories from the firm’s client alerts and published thought leadership and upcoming events/milestones. Core messaging emphasized the firm’s ongoing work with CHBs across multiple practice areas, reinforcing its capability and commitment to this client segment.
Greentarget helped create the newsletter’s template/structure, content and design, which uses clear visual breaks to distinguish content types and improve readability; high-res attorney headshots; and modern iconography to add visual interest and a contemporary feel.
Once each newsletter was sent, a link was shared via the firm’s LinkedIn account and it was made available for individual attorneys to share with their contacts, with paid spend placed behind the most recent issue.
Results
Initial results from the first three newsletters demonstrate an impressive return on investment:
– The average open rate across all three newsletters was over 50%, far surpassing the industry average of 32%. Similarly, the average click-through rate was ~7%, more than twice the industry average.
– The initial distribution list nearly doubled from 471 to 909, indicating a steep rise in interest.
– Paid LinkedIn engagement for the July 2025 issue led to 25,863 impressions, 744 clicks and the re-engagement of two highly qualified referral sources.
– The CHB newsletter campaign was recognized with a Gold 2025 PRISM award from the Greater Kansas City chapter of the Public Relations Society of America, which celebrates outstanding PR campaigns and professionals in the KC area.
The firm plans to continue releasing and improving the newsletter in 2026, further cementing Lathrop GPM’s reputation as a leading provider of legal services to closely held businesses.
