The automation process is quite simple. First step is a newsletter with a link to the website. Users can subscribe to an event.
After 5 days the automation process checks if a contact has submitted that specific for, if not >> reminder mail. If a contact has completed that form the first time or after the reminder email, they get an auto respond confirmation mail (of that form).
The automation process will set a contact status in each of the cases.
After 10 days all subscribers of that form get a confirmation mail with more event details from the automation process.
This doesn't seem any rocket science to me.
