Hey, it's Geb from Email Rev Lab!
I just landed on Nutricost's homepage and saw a massive banner screaming "35% OFF SITEWIDE with code: BIG35."
Big, bold, impossible to miss.
But here's the problem. They're giving that discount code away for free. No email required. No opt-in. No list building. Just... here's 35%, take it.
For a $540M brand with 900 employees doing nine-figure growth every year, that's not just leaving money on the table. That's setting it on fire.

The Brand Story:
Min Kim dropped out of his PhD in chemical engineering at BYU in 2013 to build Nutricost with his high school friend. They started with single-ingredient supplements and grew into Amazon's #1 creatine seller with over 900 employees across 14 warehouses in 3 states. The brand stands for simple, clean formulas at affordable prices. They even run their own NSF-certified manufacturing facility in Vineyard, Utah.
But Amazon's dominance creates blind spots. When 90% of your revenue comes from a platform that owns the customer data, you stop thinking about list building on your own site.
The Homepage Audit:
The Banner Test:
Nutricost has a huge promotional banner offering 35% off sitewide with code BIG35. It's the first thing you see. Big football field graphic. Clear call to action. But the discount code is just sitting there, publicly visible, no gate required.
The Pop-up Test:
Zero email capture. I scrolled, I waited, I moved my mouse to exit. Nothing. The banner doesn't require an email. There's no welcome pop-up asking for contact info in exchange for the discount. Just a free-for-all giveaway.
The Footer Test:
No newsletter signup form. No "Join our community" box. No lead magnet. The footer has social links and a wholesale contact, but zero infrastructure for capturing first-time visitors.
The Missed Opportunity:
Here's what's broken. Nutricost is running a 35% sitewide sale, which is likely their biggest margin hit of the year. But they're not gating it behind an email capture.
If they get 100,000 visitors this month (conservative for a top-3 Amazon brand), and 10% use that discount code, that's 10,000 buyers. But how many of those 10,000 are now on Nutricost's email list? Zero. Unless they manually opted in at checkout, which most won't.
Compare that to gating the 35% discount behind a pop-up. Even at a modest 5% conversion rate, that's 5,000 new emails per month. At a $50 AOV and 20% repeat purchase rate over 90 days, that's $50,000 in additional monthly revenue from email alone. Over a year? $600,000 in email-driven sales they're currently missing.
And that's before factoring in the lifetime value of those subscribers. A supplement brand with 1,000 SKUs could nurture those emails for years.
The Solution:
Here's the one-day fix for Nutricost's homepage.
Step 1: Gate the 35% discount behind a welcome pop-up in Klaviyo. The pop-up appears after 15 seconds or on exit intent. Copy: "Get 35% OFF your first order. Enter your email for code BIG35." This turns every discount redemption into a list-building opportunity.
Step 2: Remove the public discount code from the banner. Replace it with a CTA: "Fuel the Big Game. Get 35% OFF" that clicks through to the email gate. This maintains urgency without giving away the farm.
Step 3: Build a 5-email welcome series for everyone who opts in. Email 1 delivers BIG35. Email 2 educates on manufacturing quality (NSF-certified angle). Email 3 highlights best-sellers by category. Email 4 shares testimonials. Email 5 reinforces the 60-day guarantee. Send every 2 days.
Step 4: Add a footer signup for people who don't want the discount but do want education. Frame it: "Get supplement tips, product launches, and exclusive offers weekly."
Most supplement brands lose 50 to 70% of promotional traffic because they broadcast discount codes instead of gating them behind email capture.
Here's what I'm curious about: How much of Nutricost's $540M comes from repeat DTC buyers versus one-time Amazon transactions? If they're trying to build brand loyalty beyond Amazon, this email infrastructure isn't optional.
Min Kim built Nutricost on simple formulas and affordable pricing. The mission is "Trust the Quality, Love the Price." But when you're giving away 35% margins without capturing customer data, you're not building a DTC moat. You're subsidizing one-time buyers.
I send these audits daily because bottlenecks like this can be fixed in one day with the right information.
