Email marketing and social media marketing often go hand in hand. They both use the same tools and both aim to reach their target audience. The main difference in these two forms of marketing is how they target audiences. Email marketing typically targets an audience that has already been identified as a prospect, such as those that have already signed up for your product or service or those you have contacted before. It can also be used as an outreach tool for getting in touch with those who aren't yet customers but might be interested in your company. Social media marketing typically targets a broader audience than email marketing and can be used as a customer acquisition strategy for new members, who may not even know they are potential customers yet.
