I would like to add a widget (free, no trial, no monthly fee) that will allow visitors to subscribe to a newsletter. Once done, I want the email address to be added to a distribution list available in my existing email provider which is included in my hosting fee. My provider recommended Email Subscribers & Newsletters By Icegram. Will this cause problems with the theme in anyway? I am not partial to it if you have other free plugin recommendation that will fit better with the theme. Constant Contact seems wonderful but it is not free to use after two months and was not easily able to add it to the dashboard.
