Lifecycle Revenue Model
Campaigns are most of your sends; flows are most of your revenue per send. This model projects your annual email revenue and shows exactly how much comes from triggered flows — the business case for building them first.
The lifecycle revenue model projects your annual email revenue across two streams — scheduled campaigns and triggered flows — and shows the share flows contribute. Because flows reach people at the moment of intent, they typically earn far more revenue per recipient than campaigns (industry benchmarks put flows near 41% of revenue from ~5% of sends). Enter your list, send mix, and per-recipient revenue to see the split and the case for building flows first. Runs in your browser.
Lifecycle Revenue Model inputs and result
Run it twice. The first pass uses your current numbers and shows where revenue comes from today. The second pass assumes you have built the flows you are missing — estimate the trigger volume each one would catch per month and a realistic per-recipient figure for it — and the difference between the two annual totals is your business case for the build. Be conservative with per-recipient revenue; it is better to under-promise and beat the forecast than to anchor leadership to a number you cannot hit. Remember that flow-trigger volume is not the same as list size: a welcome flow only catches genuinely new subscribers, an abandonment flow only catches abandoners, and a replenishment flow only fires near a customer’s reorder window. Estimating each trigger audience separately keeps the projection honest. Finally, treat the output as a hypothesis to validate, not a promise to bank — confirm the actual lift with a holdout once the flows are live, because attributed revenue and incremental revenue are rarely the same number.
How to use this tool
- Enter your reachable list.Use engaged subscribers you can actually mail, not the raw list total inflated by dead weight.
- Add your campaign mix.How many scheduled sends per month, and the average revenue each recipient generates from one.
- Add your flow volume.How many people hit a triggered flow each month, and the revenue per flow recipient.
- Read the split.The model projects annual revenue and the share coming from flows — usually far higher per send than campaigns.

RGM Expert Says
The single most useful chart in lifecycle marketing is the one this model draws: campaign revenue versus flow revenue. Almost every brand discovers the same lopsided shape — campaigns are the overwhelming majority of sends but flows earn a wildly disproportionate share of the revenue, because they reach people at the exact moment of intent. Industry benchmarks put flows at roughly 41% of email revenue from about 5% of sends.
The strategic move that follows is counterintuitive to most teams: build your flows before you write another campaign. If your flow revenue-per-recipient is many times your campaign figure (it almost always is), the highest-leverage work isn’t the next newsletter — it’s the eight or nine flows that fire automatically and never need a calendar slot. Plug in honest numbers and let the flow-share figure make that case to leadership for you.
One discipline: use engaged subscribers as your list size, not the raw total. Mailing dead weight doesn’t add revenue — it lowers deliverability for everyone (see the deliverability and win-back modules). A smaller, engaged list usually earns more than a bloated one.
How it works
The model projects annual revenue from your two email streams and the share flows contribute:
- RPR — revenue per recipient, the average a single recipient generates from one send.
- Flow share — flow revenue as a percentage of total email revenue.
- Annual total — campaign plus flow revenue, projected over twelve months.

Why the flow share is the number that matters
Most email teams spend almost all their time on campaigns because campaigns are visible and due on Friday. Flows are invisible infrastructure, so they get starved — which is exactly why they are under-built and over-performing. This model exists to make that invisible truth visible in dollars.
When you see that a thin slice of triggered sends drives a large share of revenue, the roadmap reorders itself. The fastest revenue is almost never another newsletter; it is completing the welcome, abandonment, post-purchase, win-back, and replenishment flows that fire on their own. Campaigns then layer on top of a foundation that is already earning.
Run the model twice: once with your current numbers, once assuming you build the flows you are missing. The gap between those two annual figures is the business case for the work.
Flows vs campaigns: the typical shape
Directional industry split — your mix varies, but flows almost always over-earn per send.
| Stream | Share of sends | Share of revenue |
|---|---|---|
| Flows | ~5% | ~41% |
| Campaigns | ~95% | ~59% |
What operators say
Build your flows before you write another campaign — that is where the revenue-per-send actually lives.
