How I'd grow your Klaviyo revenue month by month

Hey it’s Idris from Retentiononly.

If I took over your Klaviyo account tomorrow, here’s exactly what I’d do.

No theory. No fluff. Just what has worked across 500M+ emails and $65M+ in email-driven revenue over the last six years.

Step 1: Fix acquisition first
I’d start with a high-converting popup that collects both email and SMS.

Simple structure. One clear incentive. No overcomplication.

Then I’d test the following elements constantly:

In that exact order.

The Goal

Turn more visitors into subscribers without hurting site conversion so you grow your list, generate more email revenue and shift future touchpoints from paid ads to essentially free email.

In DTC, it usually takes 5–7 touchpoints before someone buys. A strong pop-up captures as many visitors as possible, so those additional touchpoints happen via email instead of ads, driving conversions without paying per click.

Step 2: Build a welcome flow that actually converts

Next comes the welcome flow.

Not a brand story nobody reads.

But social proof, urgency and authority from the first email.

I’d also turn your best-performing ads into emails.

If it converts cold traffic, it usually converts subscribers too.

The Goal

Convert as many subscribers as possible into first-time buyers, so you get more new customers from the same ad spend, reduce CPA and increase new customer ROAS.

Step 3: Campaigns that move revenue, not just engagement

Then I’d send two to three campaigns per week.

Segmented.
Direct-response driven.
Designed to convert, not to just look pretty in Klaviyo.

Goal

Drive clicks, orders and repeat purchases.

Additionally, you wanna build a real relationship and trust with your subscribers and customers, so your brand stays top of mind and becomes the obvious choice whenever they have a problem you solve.

Step 4: Build and optimize the core revenue flows

After that, I’d build the eight core flows that drive most of the revenue.

Here are the best and worst email flows ranked

Here are the core flows

Inside those flows, I’d A/B test the highest-impact emails and SMS first.

Not subject lines for fun, but changes that move revenue per recipient.

Goal

Send the right message at the right moment based on customer behavior, so flows quietly do most of the revenue work in the background while campaigns amplify results.

Step 5: Weekly review and constant testing

Once everything is live, the real work starts.

Every week I’d review popups, campaigns and flows.

Compare weekly and monthly performance.

Track subscriber growth, revenue per recipient and flow contribution.

Then I’d launch the next high-impact split tests immediately.

Goal

Create a continous improvement loop where every week increases email revenue without adding more traffic or ad spend.

That’s how you grow email and SMS revenue every single month.

Not with hacks, but with a system that compounds.

If you want more breakdowns like this, just stay subscribed.

I share exactly what we see working across real ecommerce accounts.

Cheers,

Idris
