Case study: Evernue Media

The situation

The copy bottleneck was costing them clients.

Evernue writes a lot of email. Campaign emails, flow emails, SMS, all for a roster of e-commerce brands inside Klaviyo. The problem wasn't talent. There was just no shared way to write. Copy got pieced together across ChatGPT, Claude, Notion, and Docs, and no two writers did it the same. So every brand read a little different, and the work kept stalling.

Then it spread. Each writer could only push out 8 to 12 emails a day, so the accounts weren't getting enough volume. Projects slipped. Clients got unhappy. Some churned. And Joel, the head of operations, got pulled in to plug the gap, writing copy himself and project-managing the writers line by line. The person meant to be running the business was stuck doing the work inside it.

The obvious fix was to hire. He was about to bring on a third copywriter, maybe a fourth. But more writers meant more cost, more managing, and the same root problem underneath: no system, so no consistency. He didn't want to do it.

“I was pulled into writing copy and project-managing the team, distracted from my actual role. The accounts weren't getting enough volume, projects were delayed, and clients were churning.”Joel Adams · on life before the build

What we built

Evernue Studio , their own copy engine.

A private AI platform built for their agency, live at evernue.studio. It captures how each brand sounds once, then writes the first draft of every email from that. Built on Next.js, Supabase, and Claude.

Capture the brand once

An onboarding wizard reads the brand's website, their onboarding form, and call transcripts, then builds a Brand Passport: the voice, the audience, the products, the rules, the words to never use. Reviewed and locked.

Generate the first draft

A writer picks the brand and the type (campaign email, flow email, SMS), drops in the goal, and hits generate. The copy comes out grounded in that brand's passport, not a blank box.

Edit in a real editor

A rich editor with typed email blocks (hero, product, closing) and an AI panel on the side. Highlight a line, ask it to tighten or change the tone, and it only touches what you selected. Voice input too.

Share and ship

One share link with PDF and Word export, version history, and a flow builder for full sequences. The owner controls the AI prompts and the team from an admin console.

Brand Passport

Every client's voice, audience, and rules captured once and reused on every draft.

Same quality, every writer

The output is consistent across the whole team, because it all writes from the same source.

You own it

Deployed in their accounts. The owner edits the prompts and invites the team. No vendor lock-in.

Email + SMS

One editor for both, with an honest SMS counter and the brand's SMS rules baked in.

The results

9x faster per email. And it didn't stop there.

Faster per email

45 minutes down to 5. A writer now does in under an hour what used to eat most of a day.

14 days

Ahead on copy, agency-wide

Up from a shaky 3 to 4. That pulls the design team 7 days ahead too, with room to take on more.

5 to 10%

Of a draft now needs editing

Down from rewriting about half. The quality went up, not down.

Writers, not 5 or 6

Same small team. And Joel out of the copy seat, back to running the agency.

“I think it's the complete opposite. Instead of fixing 50% of the email, we only need to optimize around 5 to 10%. It's so much better than what it was.”Joel Adams · on whether AI hurt their quality

Why it's bigger than it looks

The real number isn't $5 to 6K. It's every hire they never make.

Skipping those 3 to 4 writers saves about $5,000 to $6,000 a month. That's the easy number to point at. But it's the smallest part of the story.

Here's the bigger one. Each writer used to top out around 8 to 12 emails a day. That ceiling is gone now, so the same two people can take on more brands without the agency hiring for it. Every new client they add lands as close to pure margin, because the capacity is already sitting there.

And that compounds. A normal agency grows by adding people, so cost climbs right alongside revenue and the margin stays flat. Evernue grows by adding clients to a team that doesn't need to get bigger. So the win isn't a one-time $5 to 6K. It's every future hire they get to skip, for as long as they keep growing. a number that never fits on a spreadsheet, and is far larger than the monthly line.

“The plan is to stay lean but bring in more clients. Even if we handle 10 to 20% more clients and don't need to hire for it, that's a winner for us.”Joel Adams

Joel got out of the weeds and back to running the business. And he's already sending other agency owners our way.

“It's crucial to move with the times or you'll get left behind. I've already pushed a few agencies in your direction.”Joel Adams

An email used to take 45 minutes. Now it takes 5.
