I use the Newsletter Plugin 1.5.9 version. I need to select the SMTP connection from the plugin. When i click on the SMTP menu, the plugin says: “You need Newsletter Extras 1.0.4+ installed to configure SMTP”.
Is it possible to have the SMTP functions in the 1.5.9 version?
I need to upgrade the plugin? Is it compatibile with the 3.3.1 WordPress version?
