How to send multiple mails at once with

Question

I am interested how mailgun or similar services does send same message to multiple users with one call to user list, like described here

Is it just simple loop for each user or there is bulk mailing options for all SMTP servers. I just want to create my own server for marketing newsletter to our users and was thinking about how to organize sending of mails.

I cannot comment on the back end of how specifically mailgun works, but I know when I have needed to do it in the past I have done it with a message, php array of emails and just sent them using php send-mail, just a for-each to loop through the list of emails and they would all be sent right off.
