Telemarketing is one of the most common forms of direct marketing in which marketers contact consumers by phone. Whether you are direct mailing to consumers at home or key executives at their office, telemarketing follow up calls will dramatically increase your return on investment. There are many advantages to allocating marketing dollars and time into telemarketing follow-up after any direct mailing list campaign. The majority of mailing lists have telemarketing telephone numbers available.The consumer direct mailing list database has phone numbers where available. Due to the National Do Not Call passed in 2003, residential phone numbers available have dropped off significantly. It is important to register with the national do not call registry as a telemarketer. Approximately 10% of all residential addresses have a telephone number available for telemarketing. As an example, if you are mailing to 10,000 households, it is realistic to expect roughly 1,000 phone numbers. Calling those 1,000 phone numbers will still have a large impact on improving the results of your overall direct marketing campaign. It is also important to note that political organizations, charities and non profits, and survey companies are exempt from the do not call and are permitted to call all phone numbers available, even numbers registered with the federal do not call.The business direct mailing list database also has phone number available for telemarketing. The advantage to the business file is that every business record on file has a phone number and are all permitted to be called. Business phone numbers are exempt from the National Do Not Call registry. That gives the advantage of being able to call and follow up on every prospect that has received your mail piece for follow-up. Combining the business phone numbers with a top contact name within the organization, can make your campaign the ultimate success.Telemarketing can also increase sales from your current customer file. Even if your current customer file does not have telephone numbers, a reputable mailing list broker provider can append phone numbers to your in house database file. You can append phone numbers to a residential or business customer. Also, if a residential customer has purchased from you within the past 12 months, they are also exempt from the national do not call.Telemarketing puts slight pressure on a potential customer to react and/or respond to your offer or product.
