We have decided to switch to the original Magento 2.3 newsletter function and have about 7000 subscribers. However when I send out a newsletter and go into my Newsletter Queue, only 600 email has been sent for the last 4 hours. This mean that it will take around 46 hours or so to send out everything. I messaged my server provider (nexcess) and they told me it is not an issue with my server. Anyone help would be great.
