Blog with SEO articles and email marketing

A site was created on the WordPress engine. A six-year marketing plan was developed and the decision was made to make authors' SEO articles and collect an e-mail base from them. This week, the third article was posted on the website. Over a half year, a base of active subscribers was collected in 1,300 people. E-mail marketing was abandoned and therefore 30 people were monetized from the entire base. It was earned $2800 net.
