My list statistic now working, but i can use only “email-user” option. When i use email all (275 people), most of people doesn’t receive e-mail and my page is blank.
For the send events meta box, i don’t have last entry because i tried to restart it. And now i send e-mail to 1 user, succesful, but there is no data in “send events meta box at the bottom of an email edit screen”. It is empty.
