You know email— but Email Marketing is a little different. Professional-looking, beautiful emails with the right message let you engage customers and reach new ones. Email marketing is directly marketing a commercial message to a group of people using email. In its broadest sense, every email sent to a potential or current customer could be considered email marketing. It usually involves using email to send ads, request business, or solicit sales or donations, and is meant to build loyalty, trust, or brand awareness.
