Data cleansing will increase your chance of mailing success by ensuring your mailed message is going to the right address, to a person who accepts direct mail and to a person who is alive!
Mailing to up-to-date & clean address lists makes sound business sense and can increase your return on investment!
We are a responsible mailing company and suggest that you have your target addresses verified for accuracy, movement or mortality before mailing. We work with W8 data, experts in this field. They offer a FREE of charge address data audit to allow you to see how your data shapes up! We can arrange this for you.
6 Reasons to Data Check
Once you have the FREE audit report of your data you can decide how to proceed. If your data looks healthy, then just ask us for a free Excel de-dupe, free formatting to remove nasties (such as commas) and free lower/upper case alteration as required. If your data needs cleansing then we will arrange W8 data to contact you to arrange this.
Now we accept data cleansing is not the most exciting of subjects, – but it could be essential in maximising your ROI. It is worth paying to remove dodgy records rather than pay to mail them!
How do W8 data cleanse data?
