A sales and marketing manager is usually a sales manager who also handles the few marketing duties a business needs. He might help create, proofread and approve ads and decide which magazines the company uses to advertise. He’ll choose which trade shows the company attends, which gifts to pass out at the booth, decide if the company hosts a cocktail party or sponsors a golf tournament and develops other promotions to keep the company in front of its specific audience. This person doesn’t need marketing, advertising, promotions, social media or a public relations background, instead using contractors or internal staff to execute these functions.
