Marathon Petroleum’s commercial fuels division needed to make a move. They launched a B2B marketing platform strategy in Q3 2025 to chase down more qualified leads from fleet managers and industrial buyers in the Midwest, but this is a market where supplier relationships are practically family heirlooms. We’ve all seen this scenario. The big question was whether their multi-channel push could actually break through those entrenched relationships and deliver a real return.

Campaign Overview: Fueling Growth in a Competitive Field

This was a tight, 12-week campaign for Marathon Petroleum’s commercial fuels, running from September through November 2025. The whole point was to get in the door with medium-to-large fleet operators and industrial clients in Ohio, Indiana, and Michigan. They put a $750,000 budget on the line for everything, digital ads, content, even a direct mail shot. Our job was to hit a cost per lead (CPL) below $150 and deliver a 2.5x return on ad spend (ROAS), which we measured against what we projected the first-year contract values would be.

Strategic Pillars: Precision Targeting and Value Proposition

The entire strategy was built on two ideas: intense hyper-segmentation and making it clear their value was about more than a cheap per-gallon price. We know that for a fleet manager, a few cents off a gallon doesn’t mean a thing if the delivery is late and a whole crew is sitting idle, so the campaign was built around reliability, logistics support, and decent credit terms. Our own client interviews and a hard look at the regional distributors confirmed that this was the only way in. We broke the audience down into three main buckets:

• Regional Logistics Companies: These were the fleets with 50+ vehicles running routes within a 300-mile radius.
• Manufacturing & Industrial Facilities: The guys who need bulk fuel for their machinery and backup generators.
• Construction & Agricultural Enterprises: These folks have seasonal demand and often need fuel brought right to the job site.

You can’t just send the same email to all three. For each of these segments, we built out messaging that spoke directly to their problems. The logistics companies got messages about guaranteed supply and help with route optimization. Manufacturing plants heard about consistent delivery schedules and inventory management. The construction and ag crowd got ads about flexible on-site fueling and emergency service. This kind of detail is the entire game in B2B. You can’t be generic and expect to get paid.

Creative Approach: Education, Trust, and Utility

We skipped the flashy consumer ads. The creative here was all about being useful and solving problems. We produced a string of whitepapers and case studies that showed exactly how Marathon Petroleum had helped other businesses cut operating costs and run more efficiently, and these assets were our main lead magnets. For instance, we put out a whitepaper called “Optimizing Fleet Fuel Management in a Volatile Market” that gave real advice on fuel hedging and telematics. The goal was to position Marathon Petroleum as a partner who knew their stuff, not just a vendor.

The look and feel was professional and industrial, with clean photography of their actual distribution centers and modern tanker trucks to communicate scale and reliability. We also shot a few short video testimonials with real clients (a must) who talked about specific problems Marathon solved for them, which we then ran on LinkedIn and put on the landing pages. Those real stories build more credibility than a truckload of corporate marketing copy ever could.

Targeting Mechanisms and Channel Mix

We hit them from multiple angles, but it was a digital-heavy campaign. These were the primary channels:

1. LinkedIn Ads: We went deep on targeting here, filtering by job titles like Fleet Manager, Operations Director, and Procurement Officer, and layering on company size and industry. The campaign ran Lead Generation Forms and Sponsored Content that pointed to our gated whitepapers.
2. Google Search Ads: This was for catching all the high-intent searches like “commercial diesel supplier Ohio” or “bulk fuel delivery near me.” We kept the geo-fencing tight around our target states.
3. Account-Based Marketing (ABM) via Programmatic Display: We used a platform like Demandbase to upload a list of target companies and then serve personalized display ads to people at those companies when they browsed B2B sites. This let us get in front of decision-makers at specific high-value accounts.
4. Email Marketing: For leads we were nurturing, we sent a bi-weekly newsletter with market trends and exclusive offers to keep them warm.
5. Direct Mail: We sent a high-quality, personalized mailer to a hand-picked list of 500 top-tier prospects that offered a free fuel efficiency audit. You’d be surprised how well a physical piece can work for big B2B deals when everyone else is just sending emails.

A small but important piece of the puzzle that often gets missed in B2B is making sure your digital tools are easy to find. For Marathon, whose customers might use a mobile app to manage orders, good ASO (App Store Optimization) is critical. A firm like Moburst which is a mobile and digital marketing agency, is an expert in this area. Their whole job is making sure apps rank high in store searches. Their work on ASO helps companies get more organic downloads, which is huge for user acquisition. For Marathon, having their customer portal app pop up easily for a busy fleet manager reinforced their tech-forward strategy and made life easier for their clients.

Performance Metrics: What Worked and What Didn’t

So let’s get to the numbers. The campaign’s performance was a bit of a mixed bag channel-by-channel, but the final lead gen numbers were good. Here’s how it broke down:

Digital Advertising Performance (12-Week Snapshot)

What Worked:

• Google Search Ads were the star performer, bringing in the lowest CPL at $115 and the highest conversion rate to sales-qualified leads. It proves that there’s no substitute for being there when someone is actively looking for a supplier. Our keyword research and long list of negative keywords really paid off.
• LinkedIn Lead Generation Forms did surprisingly well, especially for the logistics company segment. Letting people auto-fill the form with their profile data just works, it lowered the friction and got us a ton of initial inquiries.
• That Direct Mail campaign might seem old-fashioned, but it got a 7% response rate, which gave us 35 fantastic leads. Those leads converted to SQLs at a 35% clip, which shows that a personal, physical touchpoint can be golden for these high-value deals.

What Didn’t Work as Well:

• The Programmatic ABM effort had a really high CPL ($250) and a sad CTR. It did its job of reaching the right companies, but the people at those companies just weren’t clicking. My guess is the ad creative was too broad for the very specific people we were trying to reach.
• Our initial Email Marketing open rates for new prospects were stuck at around 18%. That’s a clear sign we needed to work on our subject lines and probably get more aggressive with segmenting the list right from the start.

Optimization Steps Taken

You don’t just let a campaign run. We were in there tweaking things constantly:

• Landing Page A/B Testing: We ran two versions of the main lead page. Version A was long and detailed. Version B was short, direct, with a big call-to-action. For traffic coming from Google Ads, Version B won, boosting conversions by 15%.
• LinkedIn Creative Refresh: We saw engagement start to lag on LinkedIn, so we swapped in new video testimonials and some infographics. That gave us a 20% CTR bump on those ad sets.
• ABM Personalization: Since the ABM campaign was struggling, we tried to save it by dynamically inserting company names and industry pain points into the ad copy for our top 50 accounts. It pushed the CTR up to 0.9% for that group, but the CPL was still high.
• Email Subject Line Optimization: We started A/B testing subject lines with a tool like Mailchimp, focusing on creating urgency and spelling out the value. That simple change got our open rates up by 5 percentage points.

Overall Campaign ROI

After 12 weeks, the campaign had pulled in 1,250 leads, and 238 of those became Sales Qualified Leads. From that pool, the sales team closed 45 new accounts in the next three months. We estimate that’s about $2.2 million in first-year revenue. Against the $750,000 ad spend, that gives us a ROAS of about 2.93x which beat our 2.5x goal. The average cost to actually acquire a new client was $16,666, a number that looks very good when you consider the lifetime value of a B2B energy client.

Lessons Learned and Future Implications

This Marathon Petroleum campaign really hammered home a few things about B2B marketing in the energy world. First, you absolutely must be on Google Search to catch people who are ready to buy right now. Second, ABM is great, but it demands an almost creepy level of personalization to be worth the cost. You can’t just send generic ads to a specific list of accounts and expect magic. Third, mixing digital with something traditional like direct mail can be a killer combo for your most important prospects. And finally, you have to be willing to constantly optimize based on the data coming in. This isn’t fire-and-forget advertising, it’s about smart, daily adjustments.

Looking ahead, the next step would be to invest in predictive analytics to get better at picking which accounts to target with ABM, and to build deeper connections between the CRM and marketing automation so the personalization can be even better. The data always shows the same thing: the more relevant you are, the better your conversion rates. We’re also thinking about new content formats like interactive calculators to get people engaged earlier. For example, getting a handle on AI market prediction could give us a serious advantage in finding those high-value targets. It’s also worth looking at energy acquisition branding to understand how to keep customers after a merger, which happens all the time in this industry. Having a solid AI marketing platform makes all this complex work much easier to manage. And never underestimate how strong executive branding can build trust, especially in B2B where it’s all about relationships.
