Over the last nine months I completely rebuilt my email strategy around a framework I call Dopamail.

In six months it lifted subscriber engagement 80%. Not opens. Not clicks. Real, active engagement. Button presses, poll votes, replies, the stuff that trains inboxes to prioritize you and trains subscribers to look for your name. And it’s still climbing.

Receipts. +80% engagement in 6 months on Ecamm’s weekly newsletter. Still compounding. Confetti animations are, unbelievably, part of the strategy. Read the full case study →

This post is the whole thing in one place: what Dopamail is, why it works, and exactly how to build it into your own newsletters.

What Dopamail is

Dopamail is an email framework that builds dopamine-releasing feedback loops directly into your emails. The core move is simple: instead of treating email as a one-way broadcast, you make it interactive. You give readers reasons to click, vote, reply, and react. Not just consume.

Traditional email says “here’s my content, see you next week.” Dopamail says “here’s my content. Now what do YOU think? Vote on this, try this, click here.”

Every interaction fires a tiny dopamine hit in your reader’s brain. Same neurochemical that keeps them scrolling TikTok, except now it’s strengthening their relationship with your newsletter instead of feeding an algorithm.

If you want the neuroscience version, Ali Abdaal has a great breakdown of how dopamine actually works on TikTok. Watch it, then come back. The short version: every like, every comment, every ping on social is a dopamine release literally designed to be addictive. Dopamail steals that exact mechanism for email.

The difference is what you do with it. Social media uses these loops to trap you inside their app. Dopamail uses them to build real connection with your readers.

Why it works (and why it matters right now)

Email has been around for over 50 years. It’s the backbone of the modern internet. It’s also, according to Radicati, delivering roughly 80 messages to every inbox per day. That’s 80 things fighting for attention in the same window.

Most newsletters lose that fight.

Dopamail changes the math by winning on engagement, not just content. And that engagement compounds in three places at once:

• Your reader’s brain. They start looking forward to opening you because opening you feels good.

• The inbox algorithm. Gmail and Apple Mail watch clicks and replies. Every engagement trains them that you’re wanted mail, not spam.

• Your relationship. Interaction turns a passive subscriber into a co-conspirator. Co-conspirators don’t unsubscribe.

Think about it this way. You’ve got five unread emails. One of them rewards you for clicking a button. Which one do you open first?

Social media stole from email. Time to steal it back.

Social media didn’t invent connection. It borrowed the idea from email and then added the addictive part.

Original social was about seeing your friends. Then the algorithmic feed took over and you stopped seeing your friends. Some studies showed early feeds only served up 1/3 of your actual community’s posts, and it’s gotten worse since. What replaced them was an endless scroll of dopamine-releasing recommendations. Doomscroll fuel. Anxiety in your pocket.

But the original engine, the direct-connection-plus-immediate-feedback loop, is still incredible. That’s the piece worth stealing back.

Because email has something social will never have: it’s the last direct marketing channel without a feed. The last channel without an algorithm deciding whether your subscribers see you. The last front line of direct relationship with your audience.

We just haven’t been treating it that way.

How to actually implement Dopamail

There are two ways I’ve been building this into client emails right now, with a third I’m testing. One is the easy version. One takes a little more work but lets you get really fun with it.

Easy mode: use a tool

The tool I use is List Gadget (not sponsored, genuinely just love it). It’s around $9/month and has the highest ROI of anything in my stack.

List Gadget lets you drop a leaderboard directly into your email. Readers scroll to the leaderboard section, click a button, and claim points. Simple.

Those points aren’t just a vanity metric for my client reports. By putting the leaderboard at the bottom of each email, readers are essentially marking themselves as having read the whole thing. And when they click, confetti goes off.

I have never once seen confetti and not felt a little dopamine spike in my brain. Not once.

Want to go further? List Gadget also does:

• Idea Battles (anonymous feature-request forums, which I love for customer feedback)

• Reactions (one-tap emoji responses to your content)

• Polls built for email

The magic: readers earn leaderboard points for engaging with any of it. So every poll, every reaction, every vote is another dopamine hit tied back to your newsletter. You’re retraining your audience to click every time something resonates.

Advanced mode: engagement scoring

If you want to build this yourself with liquid code and your existing ESP, the technique I use is called engagement scoring. Trickier to set up. Way more customizable once you do.

Here’s the shape of it. Every time a subscriber clicks a specific button (a poll, a vote, a “yes I want this”), an automation fires that:

1. Tags them with Engagement +1

2. Checks their engagement score custom field

3. Adds 1 to whatever number is there

Then at the top of every email, you use liquid code to show them their current score: You have 7 out of 10 points. Three more and you unlock [thing].

At 10 points, they get a free reward. Then the counter resets or ladders up. You’ve now built a mini video game into your newsletter and the reward loop runs on its own.

This is the version where you can really get weird with it. Different point values for different actions. Multiple concurrent challenges. Rewards that unlock at different thresholds. Choose-your-own-adventure sequences that branch based on their score. Once the foundation is there, you keep finding new mechanics to layer on top.

If you’re on Substack

Substack basically ships Dopamail out of the box. Your posts are discoverable, they’re part of a feed (same dopamine mechanics as social), and every post has native comments, likes, and reshares. Readers can engage with you. You can engage back. Their subscribers can find you through their reshare. The loop runs itself.

If you’re on Substack, use those features aggressively. If you’re anywhere else, you have to work a little harder, but you also get to have more fun with it.

The 80% number, revisited

I want to come back to that engagement lift because it deserves a second look, not a footnote.

80% in six months. On Ecamm’s weekly newsletter, running the full framework. Measured as active engagement (button clicks, poll votes, reactions, replies) not passive opens. And it hasn’t plateaued. Every month I iterate on Dopamail, the number moves again.

For context on what that means in practice:

• Deliverability climbed. More clicks and replies retrained Gmail and Apple Mail to route these sends to the primary inbox instead of Promotions. Free lift on top of the free lift.

• Unsubscribes dropped. People don’t unsubscribe from a newsletter they’re actively playing along with.

• Replies went up. Which matters a lot. A single genuine reply signals to inbox providers that this is real correspondence, not marketing broadcast. That signal compounds every send after.

• The list got healthier, not just bigger. Every dead subscriber a boring newsletter would have quietly lost is now either engaged or gone. Both good outcomes.

Nothing about this is magic. It’s just the same psychology social media has been using on us for a decade, pointed at something better than doomscrolling.

Give people a reason to press a button. Reward them when they do. Watch what happens.
