Outbound marketing, also called “interference” or “push” marketing, uses strategies to reach large numbers of people with a message in order to close a sale. Cold calling, direct mail, bulk email, and other approaches are used to reach large groups. It’s usually a one-way conversation about the product and why the audience should buy it. The purpose of outbound marketing is to actively establish real relationships with customers through engagement, targeted messaging and positioning your brand in the right place at the right time.
