I have been using newsletter plugin. At times I find that my site medicaljobcity.com is too slow and wonder if it is because of newsletters sent out from Newsletter plugin. I usually send newsletter to 20,000 subscribers every day through the plugin. My wordpress site medicaljobcity.com is on shared hosting “Dreamhost”. We have around 1000 sessions every day. Please advice how to optimally utilize the plugin and also to maintain site speed
Hi, if your server has not enough cpu to send such amount of email and support the traffic, there is not you can change in the plugin. Mail sending is a cpu consuming process, you can eventually use an external SMTP.
