The hour after a reader registers is your highest-value conversion window. Most publishers waste it.
You send the automated login email, maybe fire a 50% discount popup three days later, and call it a drip campaign. Meanwhile, the reader has finished the article they unlocked and moved on with their day.
That’s the moment you’ve lost.
Two of our publishers have figured out how to win it. Small Boats Magazine converts free registrants with exactly one drip email, sent 60 minutes after signup. The Moss Report converts them with 18 emails spread across two months. Same goal. Totally different sequences. Both work.
Here’s what they know that most publishers miss.
Start with the Transactional Email (Most Publishers Waste It)
The transactional welcome email gets a 70% open rate. It’s the most-opened email you’ll ever send to a new reader. Substack data confirms it, and we see it across every publisher we work with running free registration.

Most publishers treat it as a technical chore. A plain-text note with a login link and a password, and that’s it.
That’s a strategic miss. 70% of your most engaged users (they just handed you their email and created an account on your site) are going to open this thing. You don’t need a flashy marketing banner. A subtle text line at the bottom does the job: “Ready for full premium access? Subscribe here to unlock everything.”
If you’re running a free registration wall, expect 5-10% of those free users to convert to paid over time. A purposeful welcome email is one of the levers that gets them there.
Case Study 1: Small Boats Converts with One Email, Sent 60 Minutes Later
Small Boats Magazine sends exactly one drip email. It’s their highest-converting inbound asset by 5x.
Looking to grow your publication?
Sign up for expert advice straight to your inbox.Their setup: a metered registration wall. First article is free, second article requires registering for a free account. Turning on that registration step alone grows lists 500% faster than a standard newsletter signup.
Once a reader registers, the transactional welcome fires immediately. Then, Small Boats waits exactly 60 minutes.
One hour later, the reader gets a visual HTML welcome email. The copy reads:

A single “Join Now” button sits below the copy. Below that, four content blocks (boat designs, reader-built stories, adventures, plus a “more” link). A second Join Now button at the bottom. That’s the whole email.
No price on it anywhere. No discount, no countdown, no testimonial wall. It reads like a digital welcome brochure (old-school word, but it fits).
The 60-minute window is doing real work here. In that hour, the reader has likely finished the article they registered to unlock. They’ve experienced the writing, sat with the brand, and walked away feeling good. The Small Boats email hits at peak engagement, while everything’s still fresh.
The proof is in the data. Looking at their Subscriber Insights dashboard, that one email converts 5x higher than any of the other ~20 inbound sources Small Boats tracks with UTM codes.
If you’re running Leaky Paywall, the new Subscriber Insights dashboard ships with UTM tracking built in. Tag your buttons, your newsletters, any paid campaign. The dashboard tracks paid conversions by source, so you actually know which emails are moving the needle and which are noise.
If you run an enthusiast or hobbyist publication, this is the model. Your readers already love the topic. They joined a tribe. You don’t need months of education. You need to open the door and show them where to step in.
Case Study 2: The Moss Report Converts with 18 Emails (And a Bundle Up Front)
The Moss Report has been doing independent cancer journalism since 1974. They send 18 emails to every free registrant, spread over roughly two months.
Every time one of those 18 emails fires, their dashboard shows a paid-conversion bump.
This works because their audience is doing different work than a Small Boats reader. They’re navigating a serious medical situation, and they’re looking for deep, evidence-based information they can trust. You don’t build that trust in an hour. You build it across weeks of consistent, credible content.
The Moss Report makes the 18-email sequence work with two specific moves.
1. The Essentials of Cancer bundle
Instead of giving away a single article to free registrants, they package their top 20 evergreen pieces into a curated bundle called “The Essentials of Cancer.” Sign up for a free account, get instant access to all 20.
When they turned this on back in February, free registrations jumped 30%. They’ve stayed up 30% since.
The bundle does double work. It pushes the registration rate up, and it resets the reader’s expectations for what comes next. You’ve just unlocked a 20-article mini-library, so receiving 18 follow-up emails over two months feels like a guided tour of the library you joined. It doesn’t feel like a sales sequence.
2. A personal intro at the top of every email

The Moss Report doesn’t send generic automated newsletters. Every drip email opens with “Hello, healers.” Then the editor writes a personal intro with real analytical value baked into the email body, before pointing readers to the article link.
The reader gets value in the inbox. When they click through to read the full piece on the site, they land on a page where premium upgrade messaging is built in.
The Moss Report also runs articles with a time-limited free window using Leaky Paywall’s Timewall extension. A new investigation is free to read for 48 hours, then it shifts behind the paywall and into the premium archive. Their drip emails leverage that timer: read this now while it’s open, or pay to read it later.
That’s editorial urgency, not manufactured urgency. The clock is real, and it gives free readers a legitimate reason to click through today.
The Local News Playbook: 4 to 6 Emails, Built on Trust
Local news doesn’t fit either case study above. You’re not a hobbyist tribe and you’re not a high-stakes medical resource. You’re somewhere in the middle, and your drip should be too.

4 to 6 emails is the sweet spot.
Local residents who register on your site don’t want a 50% discount coupon out of the gate. They want to know who you are and why your reporting matters to their neighborhood.
Tyler from Newsletter Glue (he works with a lot of local news publishers) builds the local news drip around four pillars:
Introduce the team. Photos of your reporters and editors, plus a clear statement of your mission. Make the journalism human.
Highlight your wins. Salem Reporter uses a subject line that nails this: “Holding power accountable: how Salem Reporter works for you.” Pick a major investigation, walk readers through how you reported it, and explicitly tell them that premium subscriptions fund that exact work.
Match content to what’s actually driving conversions. Pull your analytics. If food and crime are your top two paid-conversion drivers (as they are for one New York City publisher we work with), build email two around food and email three around crime. Don’t try to showcase 12 categories in one email. The reader closes the tab out of confusion.
Run a subscriber testimonial. One of your existing paid subscribers explaining why they pay. Social proof, with a soft ask at the end. Drop it mid-sequence, not at the top.
A note on cadence: your first email or two should fire within the first hour to first day. After that, slow it down. Tyler’s rule of thumb: if you’ve ever ordered something online and gotten 15 confirmation emails in two days, that’s exactly what your drip shouldn’t feel like.
Trust Your Voice
When I interviewed Ben Moss recently, I asked him what he’d regretted most as a publisher.
His answer:
My biggest failing has not been using and trusting my own voice.
That’s the thing too many publishers get wrong. You worry that requiring registration will scare readers off. You hesitate to turn on the paywall because you don’t want to upset your audience. You hedge.
You have two superpowers that AI scrapers and content aggregators can’t steal: your content and your audience traffic. People are already coming to your site because they value your voice. Stop begging them with weak “please subscribe” popups.
Put up the free registration. Capture the email. Run a drip sequence calibrated to your audience: 1 email for niche enthusiasts, 4-6 for local news, 18 for trust-building education. Let the welcome window do its work.
That’s how you survive in today’s publishing landscape. You leverage what’s already yours.
