The connection with MailChimp is something that first needs to be activated in BestInvoicing:

1. Navigate to the top right corner of the screen (email address) and select 'Apps and Integrations' in the menu.
2. Check the list of 'Apps and Integrations Related to Customers'.
3. Click the green button 'Activate' on the line mentioning 'MailChimp'. 

## Creating a MailChimp Account

In order to set up the connection, you need to have your own MailChimp account. Different formulas are offered, including a basic free version.

Once you've entered the key, select 'Save'. You will now see a message confirming the connection has been made. 

You're offered to select a list: if you're only using MailChimp for BestInvoicing contacts, it will by default propose a list by the name of your company. New customers that are added in BestInvoicing, will also be synchronized to your customer list in MailChimp.

Do you also use MailChimp outside of BestInvoicing? You can create multiple 'Audiences' in MailChimp. When setting up the connection with MailChimp, you will be able to select from multiple contact lists (= "Audiences"). This way you can select to which audience your BestInvoicing contacts should belong.
