Hey guys, I have been selling stuff on different sites but now I want to start my own site and I need help to build my newsletter. I had talk to all the clients I had the past months through mails, but I want to add them all to a newsletter thing. What software or plugin can I use to send all these newsletter e-mails to my clients? Something so I dont have to send them 1 by 1. I am using wordpress for my site. Thanks in advance.
