Triggered mailings are a feature of ListManager Enterprise, and are unavailable for standard or Pro ListManager. Contact your account representative at sales@lyris.com if you'd like to upgrade to ListManager Enterprise.
Triggered mailings work on the premise that the time when the mailing is sent to a member depends on some action performed by that member, such as visiting a web page or making a purchase. It can also depend on some date associated with that member, such as their birthday or the date they joined the list.
Triggered mailings run on a regular frequency. This is usually once per day, but could be as often as once per hour, or as infrequently as every several weeks. The exact time of day when it runs is specified by you.
Each time the triggered mailing runs, it works the same way as any other mailing to a segment. It first calculates which members meet the criteria specified in the segment, and then sends them the mailing. What is special about triggered mailings is that they have a special type of segment called a triggered segment, or trigger for short. A key part of a triggered segment is the trigger clause. This determines who should receive the mailing right now.
Creating a Triggered Mailing
Creating a triggered mailing is much like creating a standard mailing, except that the "Schedule" tab is replaced by the "Trigger" tab. For details on the other tabs, please see:
Trigger Tab
The Trigger tab is where you select a trigger from the ones created in Segments: New Triggered Segment, and define the times for the mailing to be sent. For details on how to use the Trigger tab, see Mailings: Advanced Mailings: Trigger Tab.
