Hey, it's Geb from Email Rev Lab!
At 2:31 AM, I signed up for Stop Aging Now's 50% off offer.
The pop-up asked for my email. Then my phone number. Then a 6-digit verification code was sent to my inbox.
I gave them all three. The email came. The SMS never did.
They collected my phone number and sent nothing to it. That's not a data strategy. That's a friction tax with no receipt.
Brand Bridge
Stop Aging Now was built on Jean Carper's bestselling book on reversing the aging process. Since 1995, they've been formulating premium USA-made supplements backed by a 365-day no-questions-asked return policy. That's 30 years of trust.
But a 3-step pop-up verification flow is a trust tax. Every extra step tells your buyer, "We don't trust you yet." And buyers who feel like suspects don't convert.
The Pop-up Test
The design is clean. Logo front and center, "Celebrating 30 Years" badge, bold "UNLOCK 50% OFF" headline.
The flow is where it breaks. Email field. Submit. Phone number field. Submit. Then a 6-digit code arrives by email, and the third screen asks you to enter it to proceed.
Here's the problem. No SMS came after submitting my phone number. Not during sign-up. Not after. Nothing.
So they asked for a phone number, added a mandatory step to the flow, created friction, and delivered zero value back to the subscriber. That phone field isn't SMS marketing. It's dead weight that costs sign-ups.
The Tech Test
The email arrived at 2:31 AM, the same minute I submitted. So delivery speed is solid.
But the pop-up itself tells subscribers: "Check your inbox and spam folder for your code." That line is a red flag. Stop Aging Now already knows deliverability is inconsistent enough that they have to warn people before the email even arrives.
Fix that infrastructure issue first, then remove the warning copy. Right now, they're advertising their own weak spot.
The Inbox Test
The welcome email landed in Promotions, not Primary.
Subject line in inbox: "50% OFF Just for You — Act Now!" with a party emoji. That subject reads like a flash sale broadcast, not a personal welcome.
For a brand with 30 years of customer trust, the first email a new subscriber sees shouldn't feel like a promotional blast. Promotions tab placement confirms that Gmail's algorithm reads it the same way.
The Email Creative Test
Inside the email: a big "ENJOY 50% OFF SITEWIDE" graphic, the discount code above the fold, and two product recommendations below it.
The code is visible. That part works.
But the entire email is image-based. No real text. No personal welcome. No brand story. Just a coupon delivery wrapped in a colourful banner.
For a brand built on longevity, science, and 30 years of trust, the first email reads like a one-time promo for a brand nobody's heard of.
The Fix
Primary bottleneck: phone number field collecting data, but activating nothing.
In Klaviyo, either wire the phone field to an actual SMS welcome flow or remove it from the pop-up entirely. Right now, it does neither. A field that takes from the subscriber without giving anything back destroys trust before the relationship starts.
If SMS is the goal, send a welcome text immediately after sign-up. Something simple: "Welcome to Stop Aging Now. Your 50% off code is [code]. Shop here: [link]." That turns the phone number into a revenue asset instead of a roadblock.
Add 2-3 lines of plain-text copy above the discount code image in the email. Something like: "Welcome to Stop Aging Now. Here's your 50% off code." Plain text helps with Primary tab placement and makes the email feel personal, not promotional.
The Impact Statement
Asking for a phone number and sending nothing to it is the worst of both worlds. You added friction to the sign-up and got no SMS channel to show for it.
The Curiosity Hook
Here's what I'm curious about: how many people dropped off at the phone number step and never came back? Because right now, Stop Aging Now is paying for lost sign-ups for an SMS list they're not even using.
The Pitch
Stop Aging Now has 30 years of credibility and a product line worth promoting via SMS. They just need to actually send the texts. Right now, the phone number field is a promise they're not keeping.
I send these audits daily because bottlenecks like this can be fixed in one day with the right information.
