Frequently asked questions
What is data cleansing?
Data cleansing is the process of correcting, removing, and updating inaccurate or incomplete information in your database to improve accuracy and reliability.
Why is CRM data cleansing important for B2B companies?
Clean CRM data helps your sales and marketing teams reach the right people. It reduces bounce rates, improves targeting, and prevents wasted spend on poor-quality leads.
How does Newton Fox’s data cleansing service work?
We audit your existing database, remove duplicates, correct errors, verify contact information, and complete missing fields. Our data cleansing services and expertise enable us to deliver a compliant, ready-to-use master file that is ready for your team.
What is the difference between data cleansing and data enrichment?
Data cleansing fixes existing errors, while data enrichment adds valuable new information, such as company size, sector, or verified contact details, to improve targeting.
Can Newton Fox clean and format CRM data from any system?
Yes. We work with most major CRM and marketing platforms, aligning data formats and naming conventions so your team can act confidently on every record.
How often should data cleansing be done?
Ideally, every 6 to 12 months. Up to 10% of B2B data becomes outdated each month, so regular refresh cycles help maintain high accuracy and compliance.
Is your data cleansing service GDPR compliant?
Absolutely. All our data handling, validation, and enrichment processes follow GDPR and PECR guidelines to protect your business and contacts.
Can clean data improve lead generation results?
Yes. Clean, verified data boosts conversion rates and ensures your lead generation and telemarketing campaigns reach real, relevant decision-makers.
What types of businesses benefit most from data cleansing?
Any organisation running CRM, email, or telemarketing campaigns benefits, especially those in B2B, SaaS, finance, or professional services.
