Reading the forum, i learn about a mail marked with as "hard bounced" will not send to Amazon again.
But whats happened with the same email if i have it in a many lists?
Example : 1) In my database (my crm, not in sendy) i have my "students" list and i export all of them to send a email using sendy with the list "all students" and i have some bounces there. 2) Some day i exported from my crm a subset of my students (the girls), to invite them and i create the list "female students" to send a invitation. 3) When i send to the "female students" list, the bounces (from the "all students" list) are considerated in this send. 4) When i re import a email to another what happened with the "hard bounced" state.
