I would like adapt workflows from  answer received from recipients 

-Answers from recipients themselves,

-Request to unsubscribe (via form)

- Automatic answers (from the servers: new contacts, absences ..)

And how to customization content of the mails following actions :

Create segments or insert "variables" to adapt the content?

Thoses to adapt contacts are at different stages of maturity; (Tunnel) prospect cold, Awareness, interested ....

Another question ; Is it possible to trigger a new workflow following the result of a previous workflow?

How to personalize the contents of the mail following the events that are the ones rested with our mails
