I am running a WordPress site and have been using "Wp-opt-in" to collect emails of viewers. However, I am looking for a way to set-up a more sophisticated mailing system. I have activated MailPress and have it properly sending emails. I was wondering if anyone has every integrated these two plug-ins so that when someone "opts-in" ojn our website by submitting their email address, they receive an automatic reply with an HTML email. Perhaps, there is a plug-in in MailPress that does the same thing? Any advice would be greatly appreciated. Thanks!
