“The State of Email Attrition 2018” analyzes NeverBounce user data to determine the attrition rate of B2B and B2C email addresses.

CLEVELAND, February 27, 2018 // NeverBounce, the industry leading email verification and list cleaning service, today released a new white paper examining the average attrition rate of B2B versus B2C email addresses.

Based on user data analyzed over a 12-month period, the white paper “The State of Email Attrition 2018” looks at the average attrition rate, or “churn rate” of B2C email addresses, addresses featuring consumer domains such as “,” “,” “,” “,” etc., and B2B email addresses, addresses containing unique domain addresses specific to a business or organization. A sample set of 40 million records of valid user B2C and B2B email data gathered during a five-month period was reevaluated after a year to determine the average attrition rate of both subsets.
