What L4 Group does
L4 Group, LLC is a private digital marketing agency that delivers full-service online marketing to small and mid-market businesses in the energy and home services sectors. The firm provides website design, search engine optimization, lead generation, content marketing, social media marketing, video marketing, email marketing, and paid advertising under a single engagement model. Its customer base is concentrated in four verticals — heating oil delivery, propane delivery, HVAC contracting, and plumbing contracting — industries in which the company has operated continuously since 2010.
Service delivery is built primarily on a WordPress CMS foundation with responsive, mobile-first design and SEO-optimized site architecture. The firm integrates third-party marketing automation platforms (HubSpot, ActiveCampaign, SharpSpring), workflow automation via Zapier, call tracking and heat-mapping through CallRail, and personalized direct-mail automation through Handwrytten. Pricing is project- or retainer-based with custom quotes per client scope; engagements carry no long-term contractual lock-in, operating on a mutual 30-day notice basis.
Revenue is generated through professional services fees rather than software licensing or media arbitrage. In 2025, after approximately a decade of collaboration, L4 Group merged with Maderia Group to form Navarra Marketing, with founder Brett Lewis continuing to lead the combined operation. The merged entity preserves L4 Group's vertical specialization while incorporating Maderia Group's complementary energy-marketing operations under a unified brand; the L4 Group website remains active but directs prospects to the Navarra Marketing site.
