Hey, it's Geb from Email Rev Lab!
The Lead:
MET-Rx invented a category that generates billions of dollars a year.
In the 1980s, Dr. Scott Connelly (an anesthesiologist) built a protein formula to stop critically ill patients from losing muscle. That formula launched as MET-Rx in 1991 and became the world's first mass-market meal replacement powder. By the end of that decade, it was doing over $100 million a year in sales.
Today, MET-Rx has John Cena on the homepage, a slick product carousel, and a full-featured Shopify store.
And zero. Email. Capture.
No pop-up. No banner. No embedded form. Nothing.
The Brand Bridge:
MET-Rx literally created the supplement category. Dr. Connelly's Metamyosyn blend turned hospital nutrition science into a $100M brand. Their current tagline, "You Can't Fake Strong," is built around authenticity and earned results.
But you can fake having an email strategy. And right now, that's exactly what's happening. Every visitor who lands on that John Cena homepage and doesn't buy is gone forever, with zero way to bring them back.
The Pop-up Test:
There isn't one.
I visited metrx.com, scrolled the entire page, waited 60 seconds, and moved toward the exit. Nothing triggered. No discount offer. No loyalty club. No "join our list." Complete silence.
For a brand running paid media and a celebrity partnership, this is a significant problem.
The Tech Test:
No form means no list growth. No list growth means no Klaviyo flows to send. The welcome series, the abandoned cart, the post-purchase upsell, all of it is sitting idle (or nonexistent) because the front door is locked.
There's no email infrastructure to audit because there's no entry point being built.
The Inbox Test:
I can't report on inbox placement or subject line performance.
Because I never got an email.
The Email Creative Test:
Same answer. Nothing to evaluate.
The site itself is well-designed. The Big 100 bar product page is clean and benefit-led. The John Cena MET-RX Flex campaign looks polished.
But none of that creative energy is being used to capture or convert email subscribers.
The Impact Statement:
Most supplement brands lose 60-80% of their site traffic with no way to follow up. MET-Rx is losing 100% of theirs because there's no capture mechanism at all.
The Solution:
Here's the 3-step fix to get MET-Rx's email engine running in 24 hours:
Install a pop-up in Klaviyo. Offer 15% off the first order. Set it to trigger at 8 seconds on-site OR 40% scroll depth. Target new visitors only. This alone starts building the list.
Build a 3-email welcome flow. Email 1 delivers the discount code within 5 minutes of signup. Email 2 (sent Day 2) tells the Connelly origin story as a brand credibility piece. Email 3 (sent Day 4) features the Big 100 bar with social proof and a "complete your first order" CTA.
Set up an abandoned cart flow. MET-Rx has a full product catalog. Cart abandoners are your hottest leads. A simple 3-email sequence (1hr, 24hr, 72hr) with a 10% offer on the final send is standard for this.
The Curiosity Hook:
Here's what I'm wondering: If MET-Rx pushed even 2% of their site traffic into a welcome flow, what would their 30-day email revenue look like?
Given their price points and product volume, I'd bet it's significant.
The Pitch:
MET-Rx invented the supplement category. They have the brand history, the celebrity partner, and the product range to build a world-class email program.
They just need someone to turn the front door on.
I send these audits daily because bottlenecks like this can be fixed in one day with the right information.
Want me to audit your Klaviyo account the same way?
