Wineries urged to use phone sales to reach their best customers. When the home phone rings during dinner, do you answer it? Many people don’t, because they fear the caller is a telemarketer trying to sell them a product they don’t want or need.But it doesn’t have to be like that, according to a panel of winery direct sales veterans who spoke Wednesday during the Wine Industry Technology Symposium attended by more than 300 people. Well-timed telemarketing calls from a winery already familiar to the consumer are often welcomed and can yield a very high rate of sales, the panelists said.
