Email Frequency Optimisation Calculator
Revenue against churn, both counted.
Better frequency
4 campaigns
by $4,410 a month
Sending more loses $4,410 once the lifetime value of the extra unsubscribes is counted. Per-campaign revenue would still look fine, which is exactly why frequency decisions made on campaign reports go wrong.
How the Email Frequency Optimisation Calculator works
Most brands under-send, because the revenue from an extra campaign is visible and the churn it causes is not. Modelling both sides at once is the only way to find the frequency that maximises the total rather than the per-campaign figure.

Frequently asked questions
How often should I email my list?
Wherever total revenue less churn cost peaks — which for most ecommerce brands is more often than they currently send. There is no universal cadence.
Why does per-campaign revenue fall as I send more?
The same audience buys only so often, so extra campaigns split the same demand. Per-campaign revenue falling is expected and does not by itself mean you should send less.
How do I know when I have gone too far?
When total revenue stops rising while unsubscribes keep climbing. That is the point where extra sends are consuming list without adding sales.
Should everyone get the same frequency?
No. Segmenting by engagement lets you send more to the people who want it and less to those who do not, which raises total revenue and lowers churn simultaneously.
