"Defining these benchmarks is easy. Look at your 2–3 most successful customers — their performance determines the 'Best' benchmark. Then look at 2–3 failing customers to identify the 'Poor' benchmark. The range in between is the 'Good' benchmark."

Example

For an ecommerce email tool: Poor open rate is below 20%. Good is 21–35%. Best is 36% or higher. Customers in the Best tier are your expansion conversations. Customers in Poor are your save conversations.
