A subscriber is an individual who has opted in to receive communications from a business or organization. Subscribers can be customers, prospects, or anyone who has shown an interest in the business's products or services and provided their contact information. Email marketing is one of the most common ways businesses communicate with their subscribers, but they can also use other channels such as social media or direct mail.
Subscribers are a valuable asset to businesses because they have shown a willingness to engage with the brand and can be more receptive to marketing messages. They are also more likely to make a purchase or take other desired actions, such as sharing content or referring others to the business. By building a strong subscriber list, businesses can improve their customer engagement and drive revenue growth.
