The newsletter strategy guide for publishers.

Four ways to build an owned audience that grows, engages, and earns.

We built this from the publisher's seat.

Our founding team started and scaled WhereBy.Us, a profitable network of local newsletters that reached hundreds of thousands of readers and earned millions in advertising. We learned firsthand how hard it is to run, grow, and monetize a newsletter operation. Letterhead is the software we wished we'd had, built so other publishers can skip the pitfalls we hit.

Built with the people who run newsletters.

“

We began looking for a solution like Letterhead
over a year ago, and were unable to find
anything like it. We considered building the
tech, but realized it was going to be too
cumbersome and expensive. When we found
Letterhead, we were thrilled. Now, we
recommend each company we incubate use it to
scale their business.

Letterhead has been a great partner for us.
They were great in helping us increase
newsletter revenue and introducing new email
products to reach new audiences. Letterhead
has been responsive, flexible and knowledgeable
about our needs and our industry.

Every channel you depend on is rented.

Search rented from Google. Social rented from Meta. Even your website is one algorithm change away from a 40% drop in traffic. The platforms train AI on the content you publish there.

SEARCH

RENTED

Rented from Google. Algorithm changes can take 40% of your traffic overnight.

SOCIAL

RENTED

Rented from Meta, TikTok, X. Your followers aren't yours; the platforms are.

YOUR WEBSITE

RENTED

Sits on top of search. Now sits inside AI summaries that don't link back.

EMAIL

OWNED

The one audience that stays yours when platforms shift, paid CAC climbs, and AI floods the rest.

The only audience you actually own is the one you can email directly.

The audience you email is the audience you own.

Owning your audience means owning the relationship and the contact information behind it. Build trust over time and you earn durable engagement, secure revenue, and real lifetime value. Email is still the best channel for it, returning around $40 for every $1 spent.

Most publishers under-invest in the one channel that's theirs.

There's a gap between what email can deliver and what it delivers for most publishers.

P L AT F O R M C O N C E N T R AT I O N

About 74% of digital ad spend goes to the three big platform companies. The reach you rent there was never yours.

SAYS IMPORTANT, ACTS OTHERWISE

90% of publishers say email is very important to their future. Only 22% say their growing investment is paying off.

UNDERWHELMING INBOXES

Consumers rate publisher emails among the lowest-quality they receive. The bar to stand out is low.

BORROWED REACH

Search, social, and even your own site can lose traffic to one algorithm change. A direct email list can't be taken away.

Four ways to build an audience that's yours.

Personality

Build newsletters around your people.

Put your existing work to work.

Growth

Ask for signups everywhere.

Revenue

Build in revenue from day one.

Build newsletters powered by personality.

People follow people.

People trust people, not faceless brands.

The content game changed. Put your team's names, voices, and expertise front and center, and readers keep coming back for them.

It doesn't need to be complicated.

A great newsletter can take under five minutes to read. Keep it tight, consistent in structure, and to the point.

Build newsletters powered by personality.

An editorial workspace built for human, on-brand newsletters.

Put your existing content to work.

Your other channels belong in every send.

Connect your site and social feeds.

Work you've already published should flow into every newsletter. It drives traffic back and adds value without adding production time.

Skip the generic headline blast.

Auto-dumps of your latest links don't add value and don't perform. Mix a little original content with your feeds, and you've got something only you can offer.

Put your existing content to work.

Turn the content you already make into a newsletter in seconds.

Ask for signups everywhere.

You're not asking often enough.

Prompt signups in every place you can.

The best publishers ask on every page, with every login, and inside every other product. You're offering a real benefit to people already engaging with you, so make it visible.

Let your readers do the asking.

A referral program turns the readers who love you into a growth engine. Offer a reward for referring a few friends, and the sharing takes care of itself.

Ask for signups everywhere.

Grow, segment, and manage your whole audience in one place.

Build in revenue from day one.

Plan to monetize before you launch.

Design your ad units up front.

Every new newsletter should launch with ad units planned: format, price, and placement decided in advance.

Don't wait for a magic audience size.

Use direct-sold, self-service, and programmatic together to monetize every send. Self-service alone opens a new funnel of advertisers from the readers you already have.

Build in revenue from day one.

Plan, place, and track every ad from one dashboard.
