I'm using Mautic version 5.1.1 but I can't find the option send the emails with delay to avoid blocking. My goal is to slow down sending emails to 90 per hour. I've tried with cron jobs but didn't work. Also I read that the option was supported in older versions “How should email be handled?“ and then I can set queue and limit the messages easy. Unfortunately in the newer version 5.1.1 that option does not exist. I usually use Mautic-> Channels -> Emails from there I send the messages to segmented groups. No matter how much I tried to limit them through cron jobs they were sent immediately. Do you have any ideas on how to achieve it?
