MailChimp is an email marketing service used by companies large and small all over the world. Their product has everything your business needs to manage an email newsletter, and they give you great reporting along the way.
The Help Scout App pulls everything you need to know from the customer's MailChimp profile right into the sidebar. You can see what lists they are subscribed to, add them to or unsubscribe them from a list, and open their MailChimp profile in a click. Important to note, when you unsubscribe a customer from a mailing list, it works as if the customer has unsubscribed themselves.
You'll need a MailChimp API key to get started. Log in to your MailChimp account, click on your name from the sidebar, and select the Account option.
Click on the Extras tab, then select API keys from the dropdown menu.
Under the Your API keys section, click on the Create A Key button.
Copy the generated key and hop back to Help Scout to install the MailChimp app. Paste in your API Key then select which mailboxes to connect to MailChimp. Hit the blue Save button when you're done!
