Address maintenance and data cleansing

Nowadays, hundreds of pieces of information are pelting your company every day. However, in order to be able to use this data in a meaningful way, professional handling is required.

Valuable customer data is lost because addresses or telephone numbers have changed. Small spelling mistakes will result in a mailing not being delivered or a duplicate being created.

Keeping a customer database consistently in good quality requires some effort.
After all, impeccable address maintenance is a key success factor for any company.

What do you want to achieve?

  • safe arrival of your message

  • Data up to date

  • Avoiding returns and multiple requests


By regularly maintaining your customer data, you can reduce returns and avoid multiple calls. You’ll make sure your message gets across as intended and also cut costs at the same time.

With well-maintained addresses, you noticeably increase the chances of success of your sales and direct marketing measures.
