College students are a popular target for direct mail marketing. Using target mailing lists, direct mail advertising tailors direct mail campaigns to young, emerging individuals who are open to business opportunities, new products, ways to save money, etc.
Direct e-mail marketing and direct mail marketing (direct mail post cards, free brochures, door hanger flyers, booklets...) reach students who are less likely to regard such correspondence as junk mail as would the middle aged homeowner.
Students love email, love receiving mail and love the word "free." Direct mail services are in-tune to these sentiments and thusly inundate college students' mailboxes with tri fold brochures, direct mail letters, free booklets with "how-to" tips and advice, free mail order catalogs and other forms of direct mail advertising.
