Trigger Campaigns are event based campaigns that are launched on the occurrence of some specific activity. For instance, you may want a contact to receive your Followup email after 5 days the contact opened your first email but has not done the activity that you wanted him to do. Trigger campaign allows you to design such campaign that will launch based on the set of Rules that you define in your criteria.
Trigger campaigns are mainly useful when you have some pre-designed emails that you want to send whenever the contact does some activity and these campaigns will keep on running continuously sending emails to new contacts that satisfy the criteria. You can use a Trigger campaign to send the email containing Login details whenever a person registers on your website. You may then want to send an email guiding the customer how to use your application / product / software after 2 days of sending the Login email. These are repetative activities and you want all such emails to go at the right time without manual interpretation. Trigger campaign will let all these happen automatically.
The type of rules that Nurture allows you to create in a Trigger campaign are as follows. You can select one or more of these conditions :
1) Contact was sent this email
