Low cost and ease of implementation, targeted email advertising has become a tool that is nearly accessible to all businesses. A small beauty salon can also provide an email list and send coupon discounts for nail services or hair styling. The size and complexity of the marketing email campaign in this salon may not be large, but if the owner knows what marketing is and the campaign is targeting and implementing correctly, then the results may be more satisfactory to him than email marketing campaigns. Maybe the executor does not know what marketing email is!
