Any database very soon becomes out of date. Companies disappear, addresses, telephone numbers, contact persons change. To carry out an effective Direct-mail campaign at the least you need up-to-date facts about the addresses of the target group representatives you are interested in. As a rule the use of outdated databases doesn’t produce a desirable effect since the greater part of appeals simply doesn’t reach the addressee. The only way possible to get the working database lies in actualization of the special database organized earlier for the solution of the similar tasks or forming a new database using various sources. “Ring Round” of potential addressees is the optional means. To telephone round 5000 addressees 2 agents of your company need no less than 2,5 months. InfoServiceTelecom Call Centre service will help you to refresh the information contained in database or to create the new database in the shortest possible time.
