Posted: Sun Aug 17, 2025 9:36 am
When you use Mailchimp for sending emails, you collect a list of people who want to hear from you. This list is very important for your marketing. However, sometimes, email addresses on your list become inactive or cause problems. Mailchimp automatically identifies these problematic contacts and puts them into a special category called "cleaned contacts". These are email addresses that Mailchimp will no longer try to send emails to. This happens for different reasons. For instance, an email address might no longer exist. Or, a person might have repeatedly marked your emails as spam. Consequently, Mailchimp cleans these contacts to protect your sending reputation. As a result, this helps ensure that your emails reach the people who actually want them.
Why Does Mailchimp Clean Contacts?
Mailchimp cleans contacts to keep its email system healthy and to protect its users' sending reputation. If you keep sending emails to addresses that bounce (don't go through) or are marked as spam, email providers like Gmail or Yahoo might start seeing your emails as unwanted. This can hurt your deliverability, meaning fewer of your emails will reach your subscribers' inboxes. Furthermore, a high bounce rate or spam complaint rate can even lead to your Mailchimp account being suspended. Therefore, by automatically cleaning problematic contacts, Mailchimp helps you avoid these issues. Moreover, it ensures that you are only sending to engaged and valid email addresses. This ultimately leads to better email marketing results.
Types of Cleaned Contacts

Mailchimp might try to send to these addresses again. However, hard bounces are permanent delivery failures, like a non-existent email address. Mailchimp will immediately clean hard-bounced contacts. Another type is "complained" contacts. These are people who have marked your email as spam. It is very important not to email these people again, as it can damage your reputation. Additionally, "unsubscribed" contacts are those who have actively chosen to stop receiving your emails. While they are not in the "cleaned" category, it's crucial to respect their choice and not send to them. Finally, Mailchimp might also clean contacts that are deemed "inactive" based on their engagement history.
