There are several ways you can use an autoresponder to automomate your online business.
First, send information of various kinds. When someone emails a question, for example, about one of your products you’re able to respond in a timely way with a hand written email or put them into a series of automated emails explaining about your product. You’re then able to also add information links into those emails.
Second, launch your product to your list. Having gained the trust and credibility you need from from your subscribers, give them some emails telling of your next product and its topic, including how it can help them. You need to test email campaigns over time so optimize them, and so their focused on the topic or topics that list is interested in.
Third, deliver courses in emails. These can be freebie courses or high level paid courses, including involving email coaching.
Fourth, send updates. Keep customers and subscribers informed of new products, business developments, and opportunities. If you have a membership let subscribers to it know of the latest additions.
All, or any of this, can be part of a larger email campaign promoting your funnels of products for the list you send them to.
