How to Build a Crystal Ball for Your Email Program: A 6-Part Revenue Projection System for 2026
A few years ago, Jordan Gordon from Pilothouse was running email on the brand side — large domain, millions in email revenue, and a self-set annual target.
So he built a projection model. By December, he landed within $50K of his forecast.
Most brands don’t operate this way. In paid media, forecasts often rely on gut feel — “we’ll grow 10%” — because buyers are at the mercy of CPMs, auctions, and impression volatility.
Email is different. You control the outbound. You decide how many emails get sent. Which means your forecast can be precise — not directionally right. Actually right.
Jordan’s system breaks your program into six components. Project each one, add them up, and you have your 2026 number.
First: Your Two Warm-Up Inputs
Before you model anything, you need two numbers.
1) Top-of-funnel growth factor: Get this from your ads team — their projected Shopify growth from paid channels.
Is it: 20%, 50%, 100%? You need the real number.
2) Compound mailable list growth rate: Pull your master mailable list from your email platform and measure YoY growth. If your list grew 20% last year, assume a similar baseline.
Important distinction: Your list is a balance sheet, not an income statement. Addresses accumulate slowly and churn slowly. That makes list growth more stable than traffic growth.
👉 Don’t blindly apply your ads team’s growth rate to list size.
👉 Use historical list growth, then nudge upward if paid is scaling aggressively.
These two inputs power the entire model. From there, the program breaks into six revenue buckets.
The Six-Component Projection Model
Not all six matter equally.
Primary revenue drivers:
Strategic support flows:
Start here.
1. Campaigns (Your biggest lever)
Formula: Mailable list × campaigns sent × revenue per email sent
You’ll need to calculate revenue per email sent manually: Last 12 months campaign revenue ÷ total campaign emails sent
Jordan’s observation: this metric is surprisingly stable across brands.
Projection: Adjusted list × planned 2026 sends × revenue per email sent.
2. Welcome (Driven by new subscribers)
Welcome revenue is tied to new subs, not total list size.
Formula: New subscribers × welcome length × revenue per recipient
Pull from your email platform:
Then apply your top-of-funnel growth factor.
3. Prospect Reactivation Continuation
These target non-buyers after welcome.
Jordan’s candid take: these are often weak performers and can hurt inbox health.
If you keep them:
Formula: Prospect list × list growth × emails in flow × revenue per recipient
Shortcut: Grow last year’s revenue by the average of your two growth factors.
4. Post Purchase
Triggered by first-time buyers.
To size the audience:
Formula: Projected first-time buyers × emails in flow × revenue per recipient
⚠️ Uses top-of-funnel growth, not list growth.
5. Buyer Reactivation Continuation
Same structure as prospect reactivation — but more meaningful.
👉 For most brands, roughly two-thirds of Klaviyo revenue comes from buyers.
Formula: Buyer mailable list × list growth × emails in flow × revenue per recipient
Most of the value shows up later in campaigns via improved engagement.
6. Abandonment (The exception)
Abandonment doesn’t follow the normal formula. Instead, use: Abandonment emails per session
How to calculate: Total abandonment emails sent ÷ total sessions (last 12 months)
Then project: Projected sessions × abandonment emails per session × revenue per recipient
If you run multiple flows (site, browse, cart, checkout), model each separately.
👀 The Customer Service Shift Showing Up in 2026
Klaviyo asked 500+ ecommerce, hospitality, and retail leaders how AI and self-service are reshaping customer service, and the findings are eye-opening.
For example, 44% of respondents say AI and automation tools haven’t significantly changed the size or structure of their customer service team.
The takeaway? In 2026, self-service isn’t about fewer agents; it’s about smarter conversations.
👉 Klaviyo’s 2026 State of Customer Service Report gives you the data your brand needs to have those conversations, with insights from business leaders across the US, UK, and Australia.
