What does cleaned mean?

In Mailchimp, “Cleaned Members” refers to email addresses that have been removed from your active subscriber list because they were found to be invalid. These addresses typically bounce back email messages as undeliverable. There are two types of bounces that can lead to an email address being marked as cleaned:

1. Hard Bounces: These occur when an email is permanently undeliverable. Reasons for this might include the email address being invalid or the domain name no longer existing.

2. Soft Bounces: These are temporary issues, such as the recipient’s mailbox being full or the server being down. However, if an email address repeatedly soft bounces, Mailchimp will eventually categorize it as cleaned.
