I want to avoid that my domain gets blocked and tagged as "spammer"
Still i want to use my domain in the from and return path to promote my new website.
I have a python script reading the email address from excel and processing them by adding a name_variable to each email header.
My host allows sending 500 emails an hour and my server supports cronjob and all other you may need.
Suggest me a good solution and help me install/adapt the settings.
I need it right away. I hear that there are many ways but no one seems to be able to tell me a concrete method.
