Data preparation – from data to customer experiences

Professional data preparation lays the foundation for targeted outreach, legally compliant communication and sustainable marketing success.

Whether by post, telephone or digitally: only with complete and accurate data can you reach your customers reliably and address them correctly. CRM systems offer many functions, but without verified data, errors arise that can jeopardise trust and the success of your campaigns. Incorrect forms of address, incomplete addresses or exclusion lists that have not been taken into account do not leave a good impression – and in the worst case, may even pose legal risks. Here at yourdata, we ensure that your customer data is professionally verified, cleaned and sustainably improved. With more than 15 million refined addresses per year, we are familiar with the typical sources of error and have developed a processing chain that reliably improves data quality.

Requirements for professional data preparation

Ensuring accessibility

Addresses, telephone numbers and email addresses must be correct and valid.

Consistent forms of address and personalisation

Titles, forms of address and name components must be correctly assigned.

Ensuring legal certainty

Block lists, advertising opt-outs and GDPR requirements must be consistently taken into account.

Avoiding duplicates

Duplicate systems and redundant contacts must be identified and resolved.

Ensuring data consistency

Contradictory or incorrect content must be identified and corrected.

Making the most of automation

Data preparation processes should be made efficient through automation. Manual processing steps should be kept to a minimum.

Assess special cases professionally

Although complex cases or those that cannot be clearly automated can be detected by machines, they must be assessed manually.

Ensuring sustainability

Improvements must be permanently incorporated back into the source systems.

Ensuring measurability

Quality improvements should be documented transparently and in a way that allows them to be traced.

FAQ

Why is professional data preparation important for my business?

Neglected or inaccurate customer data can quickly lead to incorrect addressing, undeliverable campaigns and, in the worst case, legal problems. Professional data preparation ensures that your customers are reached accurately, in a personalised manner and via the right channels – the foundation for trust and successful marketing initiatives.

What types of errors are typically corrected during data preparation?

Common errors include incomplete or incorrect addresses, incorrect salutations, duplicate records, inconsistent spellings or failure to take block lists into account. These are systematically identified and rectified through automated checks and manual verification.

How do you ensure the quality and sustainability of the data?

We combine automated validation mechanisms with manual visual checks carried out by experienced data stewards. It is not just the one-off data cleansing that is crucial: the optimised data is fed back into your systems, ensuring that quality is maintained in the long term and continuously improved.

What specific benefits does clean data offer me in marketing?

With high-quality customer data, you can increase delivery rates, improve your targeting and boost the conversion rates of your campaigns. At the same time, you reduce internal workload and minimise legal risks – for more efficient marketing and sustainable business success.
