Note: Drip campaigns are only available to Premium users.
A drip campaign is an email that you send to a contact based on a specific trigger. For example, someone is added as a contact to your list. A regular email campaign sends to your contacts at the time you choose. With a drip campaign, emails are sent automatically to specific contacts as they meet your trigger and sending criteria. You can choose to send one email or a series of emails.
