What to expect

Data validation services use a combination of physical visits, data analysis and data comparison. Our methodology will measure the quality of your data set according to your data quality requirements.

Depending on your requirements, we can devise the strategy from scratch or follow an existing methodology you use.

In a typical data quality assessment, we would review:

 Accuracy and data consistency

Is all the information in each data set accurate and correctly formatted to ensure delivery?

Completeness

Is all the information required for each data set available?

 Coverage

Does the data include the entire data field as required (for example, an area, a postcode or a demographic)?

Timeliness

Are movers/disconnects/hard bounces removed from the data set promptly?

For data verification, we commonly use a five-step process:

  1. 1.Data sourcing
    We will either source reputable data with which to compare your data set or verify your information through desk research based on what is publicly available.
  2. 2.Data matching
    If using an outsourced data set, we will compare the outsourced data to the customer data, resulting in three data sets:
    1. Those unique to the customer data set.
    2. Those that overlap in both data sets.
    3. Those unique to the outsourced data set.
  3. 3.Data sampling
    We will take samples from the unique customer and overlapping data sets for detailed analysis and correction.
  4. 4.Physical address visits and desk research
    We will visit addresses, call phone numbers and use email to verify the unmatched data to either confirm it is correct or update records to ensure accuracy.
  5. 5.Data quality report
    Once we have reviewed and updated the data as far as is possible, we will supply a report to summarise the accuracy of your data, suitable for sharing with stakeholders and other interested parties.

B2B address verification
We can also source major commercial business universes to verify business data in the same way as above.

Additional options

We are also able to offer these related services to the Data Quality Assurance Service.

Email ping validation

Email address records can be cleansed by running a ‘ping’ process, which is a technical method to verify email addresses without contacting them directly.

Individual contact research 

Our researchers can review and update contact information for individual contacts using methods such as reviewing their LinkedIn profile. This ensures your database contacts are up to date and relevant.
