CLICKS are recorded when someone clicks a link in your email message.
A VIEW is when a user opens an email message that you send. We use a transparent 1 pixel image to track when a message is opened. This is important to understand because many common email clients (Outlook, Gmail, Yahoo) block images by default. If a viewer does not load images in their email then we cannot track the fact that they viewed the message. It’s possible for someone to view a message multiple times.
