Hey, it's Geb from Email Rev Lab!
At 7:34 PM, I signed up for Nuzest's 15% discount.
One minute later, the email showed up. Fast, right?
Wrong tab.
The Brand Bridge:
Nuzest started in 2012 when founder Trevor Bolland's daughter, Monique, was diagnosed with Multiple Sclerosis at 22. Instead of accepting the prognosis, Trevor spent years travelling the world, consulting neurologists, naturopaths, and nutritionists. That search became a brand built entirely on the idea that doing the work properly is the only way to go.
That's why a spam-folder welcome email stings more for Nuzest than for anyone else.
The Pop-up Test:
The pop-up was clean. "Unlock 15% off your first order." Clear headline, clear promise.
But after entering your email, a second screen appears asking for your phone number. That's two asks before a single email arrives.
Then the confirmation screen shows a code that just says "WELCOME." Not the actual discount code. Confusing on the spot.
The Tech Test:
The email hit in 1 minute. Speed isn't the problem here.
The problem: Gmail routed it straight to Spam. The reason Gmail displayed: "previous messages from nuzest-usa.com were marked as spam." That's a domain reputation signal. It compounds over time and it doesn't fix itself.
Second problem: the pop-up promised 15% off. The welcome email delivered 10% off.
That's a broken promise on the very first touchpoint.
The Inbox Test:
Subject line read: "Welcome to Nuzest - Enjoy 10%..."
That's a receipt header, not a subject line. It tells you exactly what's inside before you open it. No curiosity gap. No reason to click.
The Email Creative Test:
The email itself looks solid. Clean layout, clear discount code box, good brand pillars below the fold.
But it's sitting in Spam. Nobody's seeing it.
The Fix (3 Steps in Klaviyo):
Pull up your Klaviyo sending domain settings and confirm SPF, DKIM, and DMARC records are in place. Gmail's spam routing is telling you something's broken at the infrastructure level.
Run a deliverability test using GlockApps or Mail Tester before your next send. Find out which providers are flagging your domain so you know the scope of the problem.
Fix the discount mismatch. Your pop-up and welcome email must make the same offer. If you're promoting 15% off, the welcome email delivers 15% off. Every mismatch erodes the trust you just earned.
Emails sent from domains with poor reputation see 30-40% land in spam before a single word gets read. For a brand whose welcome email is its first real impression, that number hits harder. Paved
Here's what I'm curious about: how many of Nuzest's pop-up signups are ever actually opening that welcome email?
Nuzest's science-backed, plant-based supplements deserve email infrastructure that matches the product quality. The fixes above won't rebuild domain reputation overnight, but they stop the bleeding today.
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?
