Answer:
(C) Electronic approaches to follow-up dramatically lower the cost of marketing efforts
Explanation:
In sales and marketing, follow-up refers to continuously building future client or customer relationships in order to make a sale. This also means contacting the possible client or customer through various avenues of contact to establish a better relationship which might translate into future sales. These days, online marketing tools such as newsletter emails, make follow up much easier than offline marketing efforts, such as through phone calls.
