Inconsistent data (e.g. “Ltd” vs. “Limited”).
Spelling mistakes or typos
By entrusting us to addressing these issues for you, your data becomes a valuable business asset ready to power accurate reporting and targeted marketing.

how frequently you should cleanse data
How frequently you cleanse your data depends on how fast your contact records change but generally speaking, a full data cleanse should be initiated every 6 to 12 months.
If you’re actively running outbound campaigns or managing large databases, quarterly or even monthly spot-checks can prevent issues like duplicate contacts or invalid email addresses from creeping in.
Regular data cleansing protects your investment in CRM and marketing tools by keeping your lists accurate and ready to be analyse effectively.
our professional data cleansing process

Initial Data Audit / Brief
Step one is always the brief where we get to understand why the cleanse is happening, what data is needed and what outcomes are expected.
Data Hygiene
Before removing duplicates or validating, we need to gather data in a consistent format so that duplicate detection and validation work properly.
De-duplication
Once data is standardised, duplicates can be detected and removed accurately.
Validation & Verification
We then check which records are active or no longer trading. We also verify addresses, emails, phone numbers, and compliance flags.
Data Enrichment
After validation, we then enrich the data by adding missing details like job titles, emails, or decision-maker contacts.
Compliance & Suppression Check
This ensures GDPR compliance, suppression lists, and CTPs are applied after enrichment and verification so that no invalid records filter through.
Segmentation
Once data is clean, it can be segmented by job title, industry, product interest, or other client-relevant categories.
Clean Data Delivered
Final delivery is in the format requested by the client, ready to import/export into their CRM.
Can data cleansing be automated?
Yes, data cleansing can be automated using tools that flag issues such as: missing values, incorrect formats or duplicated contacts. However, human review is still very important when checking data accuracy
Is your data cleansing compatible with my CRM system?
Most data cleansing processes can be adapted to work with popular CRM platforms like Salesforce, HubSpot, Zoho and Microsoft Dynamics. Our team can help match our process to your system so that updates are applied smoothly without causing disruption.
Can data cleansing improve email deliverability?
Yes cleaning your data helps your emails reach real inboxes by removing invalid or inactive addresses. This lowers bounce rates and reduces the chance of being flagged as spam which protects your sender reputation score.
Does data cleansing help with GDPR compliance?
Yes, keeping your records accurate and updated supports GDPR best practice. It helps prevent storing personal data that is no longer needed and reduces the risk of contacting individuals who have opted out of communications.
