hello
A direct mail copywriter learns the features and selling points of the product or service being offered and uses them to create a compelling advertisement targeted towards a specific audience. When sent by email, it is sometimes also referred to as opt-in email to distinguish it from spam. A direct mail copywriter might be an employee of an advertising firm which requires a large volume of direct mail writing, or he or she might be hired by companies in a freelance capacity for occasional direct mail campaigns.

Thanks
