I've been searching to see if it is possible to send emails out in chunks. Because of the GDPR, I am investigating the e107 newsletter functionality. Cannot (don't want to) 'just' use MailChimp. The main issue is that on most providers you are only allowed a certain amount of emails per time unit. I.e., 100 emails per hour. I looked in the newsletter code, but as far as I can see, there is no code to perform this. I have been looking into the cron setup, but that doesn't bring me further. Is it possible to send newsletters in chunks?
