Churn Rate in Email Marketing
DIRECT ANSWER
Churn rate is the percentage of customers — or revenue — that a business loses in a defined period. Customer churn divides lost customers by starting customer count; revenue churn divides lost MRR by starting MRR. For SaaS, median annual gross revenue churn is roughly 10–14% for SMB-focused products and 6–10% for mid-market. In Email Marketing specifically, this means Segment contact list dynamically by firmographic, behavioral, and lifecycle attributes and Draft and personalize email campaigns using merge fields and conditional content blocks — all of which Hadrian's Email Marketing Agent executes autonomously on your live data.
What churn rate means in Email Marketing
The standard formula is: churn rate = (customers lost during period) ÷ (customers at start of period). A company that starts January with 500 customers and ends with 475 has a 5% monthly churn rate — which compounds to roughly 46% annual attrition, a figure that makes growth extremely difficult to sustain. This is why monthly churn above 2% for a SaaS product is generally treated as a structural problem requiring intervention, not a normal operating variable.
For Email Marketing teams, churn rate is a lever that needs consistent execution.
