Email launched properly in July 2025. In six months, it generated $453,309 in attributed revenue. Klaviyo puts the account in the top 10% of operators on the platform.
The specialty retailer I was running marketing for had Mailchimp configured since late 2022. It sat mostly unused while I focused on SEO and content. Here’s what changed.
Email is not a broadcast channel. You do not just send things to people.
A real email program is a set of automated systems that respond to customer behavior, plus a campaign calendar that teaches and sells in a rhythm. When those two things are in place, email becomes the most profitable channel you have. It keeps paying you after you stop spending money on it.
The system was missing.
Flows first. This is where most of the revenue sits.
Welcome series. The first email a new subscriber gets matters more than any campaign you’ll ever send.
Most brands send a discount code and stop there. A real welcome sequence does more than that. It tells the brand story, earns trust, and gives the subscriber a reason to stay engaged before they’ve spent a dollar. The goal is not just a first purchase. It’s to make them feel like they made the right call signing up.
Cart abandonment. Seven emails. Not one, not three. Seven.
The sequence moves through stages: reminder, validation, urgency. Each email has a different job, and the later emails exist because some people genuinely need more time. Most brands cut the sequence short and leave those people behind.
Browse abandonment. Five emails. Someone visited a product page and left without adding anything to their cart. Weaker signal than cart abandonment, so the sequence is softer. But it catches people who were interested and just needed a nudge. Most brands never follow up with them at all.
Site abandonment. Catches people who left before browsing a specific product. They landed on the site but never made it to a product page. Broader signal, so the messaging is broader. Worth running because it captures visitors the other flows miss entirely.
Post-purchase. This is where most brands leave the most money.
The first email after a purchase has one job: ask for a review while the experience is fresh. That sequence drove a consistent flow of product reviews onto the site, which then helped convert future visitors.
Later emails in the sequence cross-sell related products. A customer who just bought from you is the most qualified person you can email. They already trust the brand. The post-purchase flow is where you ask for the next purchase while that trust is still warm.
Campaigns second. Once flows are running, campaigns are fuel.
The pattern that worked: write a useful email about a product or topic, link to the related blog post or product page, send to the engaged segment. One product-focused campaign contributed to $6,200 in attributed revenue from a single send. Another drove thousands in sales the same week.
I also built a send calendar. Not blasts whenever there’s a sale. A real schedule: new arrivals, seasonal content, educational pieces, product spotlights. Consistency builds the habit of opening.
Flows and campaigns don’t do anything without subscribers.
There was an existing list — imported years earlier, never properly maintained. It was full of bad addresses, and sending to it would have torched deliverability before the program got started. So I ignored it and built a clean list from zero using a pop-up.
The list grew from three places: an on-site pop-up offering something useful in exchange for an email, organic search traffic landing on content and signing up, and Meta ads bringing new people into the funnel.
SEO and email are not separate channels. SEO built the audience. Email monetized it. When both are running, each one makes the other more effective. A subscriber who found you through search is already interested in what you sell. The email program captures that interest before it goes cold.
Most email guides skip this entirely. They treat email like it exists in isolation.
You cannot send the same email to everyone.
A customer who bought last month is not the same as someone who visited once and never came back. Sending them the same message is not just lazy. It hurts deliverability and trains people to stop opening.
The segments that mattered most were built around recency and behavior: how recently someone visited, what they looked at, whether they bought. Different segments get different messages at different frequencies.
I moved from no segmentation to proper segmentation in July 2025. The revenue curve follows that timeline almost exactly.
Six months. Systems built properly the first time and maintained from there.
The flows took a few weeks to build out. The campaign calendar took discipline to keep up. The segmentation took time to define and test.
The results came from treating the program like it had to perform. Because it did.
If your Klaviyo account is basically abandoned, the list is not the problem. The list is an asset you have not deployed yet.
