Within MailChimp, there is a campaign Click-map overlay (heat map). This is an interesting feature which can be easily overlooked. When you click on ‘View Report’ for a campaign, you will see four boxes (Opened, Clicked, Bounced, Unsubscribed).
Click on the number within the 2nd box (Clicked) and you will see a ‘Click map’ option. This visual report enables you to see which types of link are proving to be the most popular and also whether your subscribers prefer text links or image links. You will see the information presented as a percentage (click in order to see who has clicked).
