Omnis is a domain and web hosting service. I use them to host my personal, business and ministry domains.
AWeber is a mailing list management service. I use it to send out emails to my subscribers, and I utilize their blog broadcast feature, which automatically sends out quick intros of my new posts.
Formget is an easy online drag and drop contact form builder tool. I use them to collect requests, and inquiries as well as manage contact information from potential ministry clients and customers for speaking and consulting opportunities.
