Much like autoresponders, triggered emails are emails that are send out after someone completes an action. You can set a triggered email as a stand-alone or as part of a series that will be sent out at a set time after a person subscribes to your contact list or completes another type of action. Triggered campaigns can be set to trigger based on several criteria including dates, a recipient opening a campaign, or a recipient clicking on a link within a campaign.

For example, you can set up an autoresponder to be sent immediately (0 hours) after the person signs up to let them know about a promotion you are having for new users. Another autoresponder could be set up to be sent 72 hours later see how the recipient feels about your offer.
