This article sets out the process from removing participants from an organisation's Mailchimp mailing list.

If a participant has a canceled or transferred registration and their contact details have already been synced with an organisation's Mailchimp account, their contact details will remain in Mailchimp. There are two options for removing a participant from a mailing list.

1. The participant can remove themselves from the mailing list by using the unsubscribe link the next time they receive a communication from the organisation.
2. An administrator can remove a participant by following the steps below:
   1. Identify contacts that are no longer participating at your organisation, run the Participant Report and review the 'status' column. Those who have a status of ‘transferred’ or ‘cancelled’ are no longer active at your organisation.
   2. Archive the 'transferred' or 'cancelled' participant in Mailchimp following the steps in this Mailchimp support article here.
