Address Validation & Enrichment

The procurement and provision of high quality target group address data make a significant contribution to the success of your intended direct marketing and sales campaigns. Many address lists are generated automatically and show high error rates and data sets are often outdated. Furthermore, address data that has been created by hand in your own company can also contain errors. There are numerous sources of error, for example mistypes, change of street names, change of place names, moves, closures, deaths, relocation within a company, staff fluctuation etc. Every incorrect address and return cuts back the effect and effectiveness of the marketing or sales campaigns. This is avoidable!

With our network of thousands of qualified Clickworkers we will be glad to search your address data sets online. Inaccurate data will be corrected, outdated data updated and non-existent address data will be marked accordingly. This will give you immediate data, and if required, address data that is updated at regular intervals. This data will provide a basis for the successful realization of your marketing or sales campaigns.
In addition, we offer our data enrichment service to enhance the optimization of your data sets. Data can be supplemented by adding contact persons, email addresses, branches or URLs. Every optimized data set increases the value of your database, irrespective of whether you are using it for your own purposes or as a third-party provider.
To ensure the quality of the data, the information will only be collected by Clickworkers with the relevant native language. In addition, the data can be collected several times and the results can be compared.

Direct quote

“To make preparations for a direct marketing campaign, we needed the data of contact persons in 15,000 companies. We let the Clickworkers research the company websites to find or check the address and name of the relevant contact person.” …”The pace was impressive. The whole process took less than three days.” …”Honestly, for some jobs, there are no other options. In particular with regard to the duration of the implementation. We wanted to have the project realized in 14 days. We would never have managed it on our own. Agencies even estimated four weeks.”
