I have this scenario.
Subscribers/people signup for an event (web form), and system should store their info in Data Extension and send an welcome email for those who registered.
I was able to create a landing page and insert the web form (Smart Capture) and populate the registered user data to a Data Extension.
But while trying to send a triggered email to that data extension it is not populated in triggered Data Extension.
so i created a triggered data extension but i am not able to populate data into this data extension , there is no primary key in triggered DE.
Please help me
