Actionetics is ClickFunnels’ email automation software, designed to be used in conjunction with ClickFunnels. When it comes to Actionetics, you are spoiled for choice when it comes to functions. For example, you can use Actionetics to create an autoresponder, to create email lists, to make email sequences, to segment/organize contacts with tags, and to construct action funnels following certain internal/external triggers.
Prospecting and marketing are all the things you do to get people into the first of your sales funnel stages. Note that stages are broken into two or more steps wherever possible. A demo could be called a single stage, but in real life it involves a lot of things: contacting the customer, sending reminders, doing the demo, and then following up. Whatever your own sales stages look like, the support you need in managing them will be the same.
