I do free online courses by email. We have thousands of students all over the world. I need to send out lessons in sequential order starting on the day they sign up for the email course.
I would like student firstname.lastname@example.org to subscribe to a list which is a course say Theology 1
Bob then gets lessons 1-30 sent daily, weekly or whatever, in order, starting that day
A few days later Sue@ example.com signs up and she starts on the day that she signs up.
A month later Albert signs up and also starts with lesson 1 etc.
Sometimes students accidentally unsubscribe themselves. Say Bob does this at lesson 15, I would like to get him back up and running with lesson 16.
Is this sequential email feature available in PHPList?
