Hey, it's Geb from Email Rev Lab!
At 11:42 pm last night, I signed up for Ancestral Supplements' mystery discount.
The pop-up said I had one waiting. I clicked "Reveal." It asked for my email. Entered it. Then it asked for my phone number to activate the discount. Entered that too at 11:43 pm.
The next screen said: "Check your texts and REPLY 'Y' to get your discount code in the next two minutes."
I waited.
No SMS came.
The Brand Bridge:
Ancestral Supplements built "The Beef Organ Supplement Movement" around one mission: to put back in what the modern world left out. They source from the most pristine grass-fed cattle in New Zealand and Australia, freeze-dried and encapsulated, so anyone can access what our ancestors ate. 100,000+ reviews. 3M+ customers. Doctors on the homepage. Ancestral Supplements
This is a brand that earns trust the hard way.
Which makes a broken welcome promise hurt more than it would for anyone else.
The Pop-up Test:
The mystery discount hook is genuinely smart. Curiosity-first, no discount size revealed upfront. Solid.
But the flow has a two-step ask: email first, then phone number to "activate" the code. That's a second commitment after the first one was already made.
Every additional field beyond the email address reduces pop-up completion rates. Buyers who drop off at the phone step never enter the SMS flow at all. They just leave. With nothing.
The Tech Test:
This is where it breaks.
I entered my phone number at 11:43 pm. The screen confirmed I'd get a text with the code "in the next two minutes." That text never arrived. Not in two minutes. Not at all.
Meanwhile, my email arrived at 11:42 pm. One minute before I even gave my phone number. It landed in Primary with a 20% discount code already in the hero: WELCOME202J925KJ6.
So the buyer has two problems at once. The SMS promised on screen never showed up. And the email, which did show up, contains a code the buyer was never told to look for because they were told to wait for a text.
Two systems. Two codes potentially. Zero coordination. And a first-time buyer sitting there wondering if the brand is scamming them.
The Inbox Test:
Primary inbox. That's the one win here.
Subject line: "Your Mystery Offer Is Inside." Weak for what the pop-up set up. After three screens of mystery discount energy, the subject line needed to pay that off with specificity. It didn't. A buyer who missed the email because they were waiting for a text would never know to go look for it.
The Email Creative Test:
The email is strong visually. "Welcome to the Tribe," Dr. Ken Berry's quote, the 20% code front and center. The HSA/FSA section is a smart trust add.
The problem: most of the copy lives inside image blocks. If images don't load, the buyer sees almost nothing. No code. No instructions. Just an empty dark banner. That's a deliverability risk on top of an already broken SMS experience.
Four CTAs compete for attention on a first-touch email. A new subscriber needs one next step, not a menu.
The Fix (Klaviyo + SMS platform):
Test your SMS flow right now. Enter a real number. Wait. If the text doesn't fire in two minutes, your SMS trigger is broken or your carrier compliance settings are blocking automated messages. Fix this before one more buyer hits that screen.
In your Klaviyo welcome flow, add a fallback branch. If a subscriber submits their phone number but has no SMS consent confirmation after five minutes, trigger an email that says: "Couldn't reach you by text. Here's your code." One email. One code. No confusion.
Set the same discount code across both channels. Email and SMS should send identical codes. A buyer who gets both should never wonder which one works at checkout.
Cut the welcome email to one CTA: the discount code and a single "Shop Now" button. Move the brand story, product grid, and free consult offer to Emails 2 and 3 in the flow.
The Impact Statement:
A broken SMS trigger means every buyer who completes the phone step gets a promise with no delivery. They gave Ancestral their most personal contact details and got nothing back.
The Curiosity Hook:
Here's what I'm curious about: how long has this SMS flow been broken? Because if it was broken last night when I tested it, it was probably broken yesterday too.
Ancestral's mission is to restore what the modern world left out. The irony is that their welcome flow is leaving buyers with exactly that: nothing.
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?
