It is alarming how fast a database can go ineffective. Every year, about 25% of the data that is contained in your data lists becomes redundant. This may be due to various reasons like a change in job, change in the geographical location, change of the mobile service provider, etc. Therefore, it is important to keep updating the list at regular intervals of time. Not just the removal of irrelevant or inordinate contact data, it is necessary to add-in fresh and current contact details of the qualified clients as well. By managing your data lists in the best possible way, you ensure that all your marketing initiatives propel your business towards a higher number of sales. Consequently, your business will reach a high pinnacle of ROI.
