Hey, it's Geb from Email Rev Lab!
At 12:48 this morning, I signed up for Pure Protein's 10% discount through their pop-up.
Their confirmation message said: "Thanks for subscribing, check your email for 10% discount."
It's now 1:04 am. Sixteen minutes later. Still nothing.
That gap is costing them buyers every single day.
The Brand:
Pure Protein has been around since 1995. Thirty years in, they're the #1 selling protein bar brand in America under 1440 Foods' portfolio. Their mission is to help people "Live Deliciously." High protein. Low sugar. Big flavor. Built for everyone.
They sell everywhere. Walmart. Target. 7-Eleven. CVS. Kroger.
But none of that reach matters if a new subscriber signs up at midnight, checks their inbox, and finds nothing waiting for them.
By the time that 10% discount arrives, they've already closed the tab.
The Pop-up Test:
The pop-up is clean. Blue background. Bold "WELCOME!" header. A hand wave emoji. The offer is clear: subscribe and get 10% off your next order.
The photography is excellent. Their new AMMMAZE bars, Blackout Cake and Strawberry Shortcake, are front and center on the right side. Visually, it's a strong pop-up.
The confirmation message fires right after signup. "Thanks for subscribing, check your email for 10% discount." That's a good cue. It tells the subscriber exactly what to do next.
Problem: that cue sends them straight to an empty inbox.
The Tech Test:
This is the primary bottleneck.
Sixteen-plus minutes between signup and email delivery is a conversion killer.
According to Invesp, welcome emails sent in real-time convert at 4.01%. Delayed sends convert at 0.94%. That's a 327% gap. All from timing alone.
Invesp also reports that 74% of subscribers expect to receive a welcome email immediately after they subscribe.
A subscriber who signs up expecting an immediate discount code is in buying mode right now. Sixteen minutes later, they've moved on.
The Inbox Test:
Because the email hadn't arrived during the audit window, inbox placement and tab landing couldn't be confirmed.
That's worth noting on its own. A delay this long often points to a flow trigger issue in Klaviyo, a Smart Sending conflict, or a Shopify integration sync problem. Any of those can push a welcome email from instant to delayed.
The Email Creative Test:
Can't audit what isn't there.
What I can say is this: the pop-up creative is strong. That energy needs to carry into the welcome email itself. A 30-year-old brand with clean packaging and solid photography has everything it needs to send a killer first email. It just needs to actually send it.
The 3-Step Klaviyo Fix:
Go to Flows in Klaviyo. Open your Welcome Series. Check the trigger. It should be set to "When someone subscribes to a list" with zero time delay on the first email. If there's a delay filter, remove it.
Check the flow's Smart Sending settings. If Smart Sending is turned on for the first email, turn it off. Smart Sending skips contacts who received an email recently. It should never apply to your first welcome email.
Test it yourself. Sign up with a fresh email address. Time for the delivery. If the delay persists after removing those settings, check your Klaviyo integration with Shopify. A broken sync can cause trigger delays on form submissions.
According to Invesp, real-time welcome emails convert at more than 4x the rate of delayed ones. The gap between promising a discount and delivering it is where Pure Protein is losing buyers right now.
Here's what I'm curious about: how many people sign up for that 10% discount and never buy, because the code never hit their inbox fast enough?
Pure Protein has the brand, the 30-year track record, and the distribution. They need the email infrastructure to match.
I send these audits daily because bottlenecks like this can be resolved in a single day with the right information.
Want me to audit your Klaviyo account the same way?
Reply to this email, and I'll send you a free breakdown of where your welcome series is leaking revenue.
