I have a website, and i added a subscriber plugin which pops up a subscribing window for my visitors. In order to browse the site, they have to either close the window (it will pop-up again when opening another page), or submit their names and addresses. I have the option to CSV Export my list at anytime. This is my first time building email list, am i doing this right?Is anything that i need to know?I've read something about verifiyng the emails.how do i do that? Any good tutorial will help too.
