Effective Internet Marketing

Marketing questions for a small catering company.?
What is probably the least effective marketing tool for a new business? A. direct promotional mail to the mailing list B. An Internet web page add in the CA screen D. A Yellow Pages ad in the local newspaper I can only to three and need a little help deciding what to cut out.
Although all can be effective, I would assume the cost is important too. So response along with the cost weight, I cut the Yellow Pages. The mailing list is important, as are people who have shown interest in your business .. A page web is super cheap and can change every day or the seasons or holidays. Advertisements in local newspapers can also be changed regularly to reflect the holidays or seasons, and may be more affordable than the yellow pages.
