How Warners Group Publications doubled return on ad spend by replacing guesswork with first-party data

Warners Group Publications connects people with their passions, in print, digital, live shows, audio, travel, and education, across 25 brands and more than 5 million people. Running that many brands with a lean team means constant pressure to do more without more budget, more headcount, or more hours in the day.

Ben Romaine, Marketing Manager, and Katherine Brown, Head of Marketing and Advertising for BirdGuides, opened their Dotdigital Summit session by asking the room a simple question: who in here feels time poor, under pressure, and expected to deliver more with less? Every hand went up. It set up exactly the problem they’d spent the last year solving. Not by doing more, but by finally using the data they already had.

The same problem, showing up twice

For years, Warners Group leaned on paid advertising to reach interest-based audiences, and it worked, but it wasn’t cheap or precise. “Historically we’ve been paying a premium across paid advertising channels to reach those interest-based audiences,” Ben explained, “mainly because we have no control over these audiences.”

Meanwhile, the data that could have fixed this was sitting right there, just disconnected from anything useful. The shows team had rich purchase data from ticket sales running through Eventbrite. BirdGuides had web behavior data clearly showing which visitors were spending time in its most valuable membership-gated feature. In both cases, the signal existed but nobody was acting on it.

“We had the data but we weren’t using it where it mattered most,” Ben said of the shows business. Katherine put the BirdGuides version of the same problem more bluntly: “We had the data and an opportunity to convert, but we just weren’t doing it.”

Building one connected data foundation

The fix started the same way in both cases: making Dotdigital the central hub for customer data rather than a bolt-on email tool. For the shows team, that meant syncing Eventbrite ticket sales so every purchase became order insight against the customer record, then layering in subscription, membership, and ecommerce data on top. The result was what Ben called “a rich profile of that user,” a genuinely holistic view instead of scattered fragments.

From there, the real shift was exporting those segments straight into Google and Meta instead of keeping them siloed in email. Past show attendees got excluded from campaigns advertising that same show. High-value segments got prioritized for spend. Email and paid social stopped being two separate channels and became one connected story, powered by the same first-party data.

“So why guess when the data is already telling us who matters?” Ben asked the room. That line is the whole session in one sentence, and the shows team’s numbers back it up: total ticket purchases up 56% year over year, return on ad spend more than doubled, and cost per purchase down roughly 7%.

We stopped guessing and started letting Dotdigital tell us exactly who mattered. Ticket sales, membership conversions, ad spend, all of it got sharper the moment we connected the data properly.

Turning intent into memberships

BirdGuides took the same foundation and pointed it at a more specific problem: converting the anonymous intent from those sightings-page visits into paying members. The team built an automation that enrolled those visitors, minus existing members, into a series designed to educate first and sell second, then extended the same segments into paid social so the message followed people across channels, not just their inbox.

For the free trial specifically, sign-up stayed deliberately frictionless, just an email and a phone number, and they ran a 54-day, seven-email journey using Dotdigital. The tone shifts on purpose as the trial progresses. No mention of pricing in the early welcome emails. A soft upsell once a week remains. A clear reminder of what’s about to disappear once the trial ends.

“It works because it’s simple, it works because it’s replicable, and it works because it’s proof.”
Katherine Brown Head of Marketing and Advertising, BirdGuides

The program converted at 12.3%, against an industry standard of 5 to 10%, and generated £10,000 in revenue in year one. Two emails alone, the seven-days-to-go message and the expiry-date message, accounted for 68% of that total. A related automation targeting high-intent, non-member visitors added another £6,000 in direct revenue on its own, converting 70 new memberships at an average value of £82 each, with lifetime value still to come on top.

Backing instinct with proof

Both teams tested their way to certainty rather than relying on gut instinct. When BirdGuides A/B tested send day, midweek against weekend, weekends won clearly. “Rather than relying on our gut,” Ben noted, they had the data to support the call instead of just a hunch about what people do on their days off.

Looking ahead

Warners Group has recently onboarded Dotdigital’s Personalization, and because the business is fundamentally about content, that means recommending the right article, video, or podcast to the right reader, not just the right product. The next step is extending the shows team’s Meta and Google integration into the BirdGuides free trial programme, so every touchpoint tells the same story no matter where a customer encounters the brand.

“Get the fundamentals right,” Ben told the room. “Good use of data beats complicated automation.” For Warners Group, that’s meant one platform, one connected data foundation, and two very different problems solved the same way.
