Their Best Campaign in Brand History, Built in Our First Month Together.

This client came to us with a healthy Klaviyo list, a product people already loved, and a genuine connection to Earth Day as a brand moment. In our first month together, we ran a three-day campaign across email, SMS, and flows, and it quietly became the best-performing campaign in their history, including Black Friday and Cyber Monday. The $32K was great. The context behind it is what we actually want to talk about.

The Starting Point

What We Had to Work With

The list was in good shape, the brand had real seasonal relevance, and the product genuinely fit the moment. What was missing was a coordinated strategy, one that sequenced the channels intentionally, rewarded the most loyal customers first, and gave every touchpoint a specific job to do.

The challenge wasn't finding the opportunity. It was building a campaign structure that could extract its full value across three different channels without over-sending, fatiguing the list, or leaving revenue on the table.

That's what we spent our first month figuring out together. The result was their best campaign ever.

The VIP email went to 1,934 recipients and generated $4,977 — at a 56.7% open rate and 5.01% CTR.

That's more revenue per recipient than any other campaign in the window. Your most engaged subscribers aren't just your best customers — they're your proof of concept. Lead with them, and the rest of the campaign structure becomes much easier to call.

The Strategy

Five Moves That Built the $32K.

01

VIP Early Access Sequencing

We led the sale with the most engaged segment before the full list heard anything. VIP early access rewards loyalty, signals exclusivity, and consistently produces outsized efficiency — here it generated a 56.7% open rate and 5.01% CTR from fewer than 2,000 recipients. That performance became the proof of concept that validated the rest of the campaign structure.

02

Coordinated Email + SMS Timing

Rather than treating email and SMS as competing channels chasing the same window, we sequenced them to amplify each other. The VIP email was followed by a VIP SMS that achieved 33.3% CVR and $6,098 in revenue. The main Earth Day send used both channels simultaneously to capture the broadest intent window during peak sale hours.

03

Channel-Specific Messaging

Email and SMS audiences behave differently. Email gave us space to tell the product story, showcase the line, and build context for the sale. SMS was kept tight — high urgency, short copy, one clear action. That discipline is what kept SMS conversion rates between 20–33% across all three campaign sends.

04

Last Chance Urgency at Scale

The final email send went to 120,255 recipients and drove $7,026 despite deliverability challenges affecting open rates. Urgency messaging at the close of a sale window re-engages browsers who saw the offer but didn't act. At scale, even a lower conversion rate produces meaningful revenue — which is why the last-chance send remains a reliable part of the campaign structure.

05

Pop-Up Form During Peak Traffic

We ran a pop-up form during the sale window to convert visitor intent into a list asset. The form achieved a 5.29% submit rate — 157 submits from approximately 3,000 views — and generated ~$1.8K in revenue through triggered flows. High-intent sale moments are one of the most underutilized opportunities for list growth, and this reinforced that.

Key Takeaway

What This Tells Us

The VIP segment came close to matching revenue from a send 13x its size.

Leading with your most engaged customers before opening to the full list doesn't just reward loyalty. It validates your offer at a smaller scale before you commit it to 120,000 recipients.

The thing we're most proud of here isn't any single metric. This was our first campaign together, and it became their best one. That's the kind of start we aim for with every new client.
