In E&P’s Email Master Class, publisher Mike Blinder interviewed two experts—Letterhead CEO Chris Sopher and VP Marianne Maniero—on turning email from a time sink into a revenue engine. The conversation zeroed in on four demands from registrants: monetizing beyond basic ads, growing subscribers in crowded inboxes, running newsletters with lean teams, and proving ROI to advertisers. Sopher and Maniero treated newsletters as products, aligning revenue to format and reader intent, and showed how smart automation preserves the editorial touch while scaling.
Treat newsletters as products—and put a P&L behind each one
Sopher opened with the core principle: “These things are products, right? It’s not just a distribution channel. It’s not just a way to mail out the stuff you’re doing on other channels and try to get people to click on it. It’s its own editorial product.” He argued that success starts with product thinking and discipline: quantify time, cost, and revenue for each newsletter and evaluate it on its own merits. “Here’s how much it costs to make this product… Here’s the revenue potential for it in the form of direct sponsorship and advertising, traffic to our website, monetization of products and services, donations, memberships, subscriptions…”
That P&L posture lets teams right-size ambition to capacity and revenue realities, rather than treating email as a generic blast channel. It also reframes editorial choices—purpose, format, cadence—as business levers.
Know your niche: align revenue to the product and the reader
A central theme was fit. Sopher cautioned against one-size-fits-all monetization: “It’s not one size fits all. It’s really like, what is this product? Who is it for? Where are they reading it? What’s going on?” Bespoke, personality-led digests can support handcrafted sponsorships; short, high-utility headline roundups may lean toward simpler placements, affiliate, or commerce. Crucially, niche beats bulk: “We hear all the time from publishers who are having an easier time selling their smaller, more niche and targeted products and a harder time selling their big general lists… That doesn’t surprise us at all.”
Maniero connected that to psychographics: “The power of the newsletter audience goes way beyond just the size of the subscriber list. It’s the strength of the engagement and the community that you build.” Even without full demographic detail, interest signals (health, fitness, food, business) match advertisers to intent, driving relevancy and yield.
Measure what matters (and what’s possible): metrics are changing
Email measurement is shifting under privacy changes. Sopher was blunt: “Your open rate is a range. Anyone who tells you your open rate is a number is lying to you.” With prefetching and caching from providers, platforms either show a larger, inflated figure or a smaller, verifiable one—so treat opens as directional. And links aren’t immune: “Providers like Apple are also getting into the business of stripping UTM tagging… It will get harder to track clicks…” The antidote is balancing the quant with the qualitative: surveys, polls, and reader feedback to understand perceived value and product fit.
Maniero reinforced getting the math right today: “It should be really based on a CTO or, which is unique clicks to unique opens… you really want to fully understand your metrics because it’s in your best interest to really know the truth, even if it’s painful.” That true baseline lets teams set realistic targets, adjust subject lines and formats, and benchmark progress.
Design for the job: inbox-read experiences vs. traffic drivers
Don’t force every newsletter to be a click machine. Sopher noted different product jobs require different yardsticks: “We have customers who send newsletters that are designed to be read in the inbox… It’s like I consume the whole thing and I don’t need to click on anything… Neither one’s wrong. It’s just a question of like, what product strategy are we doing for which audience for which thing?” If leadership expects site sessions from an inbox-read essay, the metric won’t match the mission—better to pair that product with a separate traffic-focused briefing.
Growth playbook: make signup obvious, use swaps, and give choices
On acquisition, Maniero called out a common, costly mistake: “Often we have to hunt for the signup form. It should be on every page. It should be prevalent at the top, not buried at the bottom.” She also advocated cross-marketing with complementary brands and, critically, choice: “If you’ve got multiple newsletters… giving people the option to decline one but stay on the other… Sometimes we’ll see people with one unsubscribe button and they end up losing them from five other channels…” Clear value propositions and visible CTAs matter as much as distribution tricks.
Churn mindset: focus on fans, not unsubscribes
Publishers often obsess over unsub emails or daily dips. Sopher reframed the effort: “It’s going to have a much smaller impact than focusing on the people who are highly engaged… find those fans and how do I replicate those fans and find more of them?” He contrasted the publisher’s promise with spammy political lists: “They don’t care about the longevity of the list… So they just spam the absolute shit out of you… You as a publisher want to be on the opposite end of that landscape… It should feel that kind of personal.” Keep the compact you made at signup; deliver what you promised at a cadence that respects attention.
Operating with lean teams: Automate (but keep the editorial touch)
Many attendees asked if small teams can run serious programs. Maniero’s answer: yes—if you productize workflow. “Global Post has literally three people on their team and they’ve got hundreds of thousands of subscribers… How do they do that? They do it with the automations… It’s a simple system with drag and drop blocks…” The efficiency gain is tangible: “Almost every call… the answer is always two or three hours… When we get switched over to Letterhead. The efficiency cuts that time in less than half.”
Sopher added nuance on automation levels: “We see a lot… 50, 60, 70, 80% automated newsletters… our system is helping you, but it’s not removing the value of that editorial layer.” Automation should pull trusted content; human curation preserves voice, trust, and that small “touch” that keeps readers coming back.
Selling value: Market penetration beats vanity numbers
When advertisers ask “what did I get?”, Sopher advised re-anchoring the conversation: “It’s all relative, right? It’s about market penetration, not about a gross number, right?” In local contexts, a five- or ten-thousand-person daily audience can rival a venue’s reach; the point is engaged mindshare with defined buyers. Chasing platform-scale metrics is a losing game; defining the market and your share of it resonates.
Maniero laid out a sales cadence that moves beyond one-off placements: “The advertiser is always going to take you back to the metrics… Impressions are the key…” But don’t sell isolated ads—sell programs: “You don’t sell them one ad at a time… you sell them a plan… it’s an awareness campaign to start with, and then it becomes…” She cited a Skimm example, reframing a mattress buy into a broader “sleep” campaign to unlock bigger results. And remember halo effects across channels: “They may have read it in the newsletter, but maybe later they’re on your website… All of those channels work together.”
Common mistakes—and how to avoid them
Maniero’s first caution: “Hammering your audience, just sending way too many emails…” Frequency without purpose erodes reputation and engagement. Equally risky is flying blind: “You should have a really quick view… to see the impact of the work that you’re doing… I just came from a call… they had no idea what their open rates were.”
Sopher recommended a one-pager for each product—purpose, audience, structure, success metrics—to prevent the “Christmas tree” effect where every team hangs an ornament on a single send: “If you’re not careful about productizing that strategy… you end up with… huge emails… because every part of the business… is trying to… squeeze a little value out of the channel.” He also pushed teams to talk to readers, not just dashboards: qualitative insights reveal the small personal touches that build loyalty.
Cadence and segmentation: Consistency, context, and spin-outs
On frequency, Maniero differentiated by product: “It’s fine to have a newsletter go out on a daily basis and then have news alerts… On a news newsletter, people expect that…” But promotional lists shouldn’t ping three times a day. Instead, be consistent, segment by interest, and let demand inform new launches: “If you’ve discovered that you’ve got a high interest in food… why not spin off another newsletter and start to grow that? You’ve already got a base developed.”
Onboarding and integrations: reduce friction, protect deliverability
Finally, what happens when a publisher is ready to level up? Maniero described a guided process: “It is very seamless, regardless of the size… you are immediately assigned a customer success manager… We hold your hand all the way through… we will do Advanced list cleaning if it’s required… guarding them from damaging… their reputation before their first send.” Sopher emphasized that Letterhead can layer into existing stacks: “We work with the vast majority of CRM and email service provider solutions… We can integrate with those products and help you 10x your newsletter execution, save time, drive more revenue, increase the opening click rates.”
Takeaways
Across strategy, measurement, sales, and operations, the throughline was clarity of purpose and respect for the reader. Treat each newsletter as a product with its own P&L. Align revenue to the experience you’re building. Balance changing metrics with qualitative feedback. Make growth easy with visible CTAs and choice. Automate the busywork to preserve the human touch. Sell market penetration and multi-touch programs, not just impressions. And above all, keep the promise you made at signup.
Two closing reminders captured the spirit of the session. From Sopher: “It’s not one size fits all… Matching the design and the layout and the metrics we measure to that” protects product integrity and performance. From Maniero: “You’re working for both”—reader and advertiser—“so… be relevant,” visible, and consistent, and the list becomes an engine that compounds value over time.
