title: How to set up a newsletter sent via php code on your centos 8 server and an external service
body: <p>I have a problem and I would like a couple of tips from you. I have a corporate email @ example.info relating to my example.info website hosted on godaddy. I have searched on google but I have not found any guides on the matter, how can I create a php code on my centos 8 server that sends a preset newsletter when I decide it?
  1- I just need to know if it is possible to link my php code to an @ example.info externa email and how to do it.
  2- Furthermore, I would need to know how to send a newsletter to more than 8 thousand people without being entered as spam by google or other such problems.
  I opted for this solution because I found on the internet that gmail doesn't allow you to send more than 100 emails automatically or something like that, so I created my own email to do the same thing but bypass the limitation.
  Anyone who can explain to me how to do or link me a guide, is welcome. Thank you</p>
