Morphy SMTP Server will shoot unlimited emails at the speed of 1500 emails to 5000 emails per hour if not throttled, which is harmful to the reputation of the ip and domain. Hence we recommend you to reduce the speed (throttle) of email sending to 250 emails per hour or 300 emails per hour using the settings inside morphymail email marketer. If throttled, you can use your server without getting blacklisted for a long period of time.
