Sending Issue | WordPress.org

Have been using the Icegram Express to send out notification of new post emails since around May 2020. Notification email sent on July 27th went out to roughly 4500 subscribers. about 75(typical) opened. Next sent August 6th and now a few more new post and test post show as sent and report the date and time started and completed and reflect number sent. All have 0 opened. Through sampling and testing of small list in the campaign have concluded they actually have not been sent. Using Bluehost as our hosting. Any ideas or suggestions? Thanks in advamce
