Data Cleansing
Real metrics from active client engagements — not projections.
Why data cleansing matters
Poor data quality silently undermines every campaign, forecast, and decision your revenue team makes.
Dirty data costs companies an average of 15-25% of their revenue. Duplicate records, invalid emails, and outdated titles don't just waste your SDRs' time — they damage your sender reputation, inflate your CRM costs, and make it impossible to measure campaign performance accurately. Data cleansing is the foundation that makes every other marketing investment work harder.
Revenue impact
Bad data costs B2B companies 15-25% of revenue through wasted effort and missed opportunities.
Reputation risk
High bounce rates damage sender reputation, pushing future campaigns into spam folders permanently.
Wasted SDR hours
Reps spend up to 30% of their time researching, cleaning, and correcting contact data manually.
Compliance exposure
Outdated suppression lists and missing opt-outs create regulatory liability under GDPR and CAN-SPAM.
Pipeline accuracy
Inaccurate contact data skews pipeline forecasts and leads to missed quota targets quarter after quarter.
CRM bloat
Duplicate and stale records inflate your CRM seat costs and make reporting unreliable across every team.

What exactly does data cleansing involve?
We remove duplicates, correct formatting errors, standardize fields (names, titles, addresses), and validate email and phone data. Every record is cross-referenced against multiple sources to ensure accuracy.
How do you handle duplicate records across systems?
Our deduplication engine uses fuzzy matching on name, email, company, and phone — catching near-duplicates that simple exact-match tools miss. We merge the best data from each duplicate into one golden record.
Will cleansing break our existing CRM workflows?
No. We map to your existing field structure and deliver in your preferred format. We can also push directly into Salesforce, HubSpot, or your CRM of choice via API, preserving all custom fields and relationships.
How often should we cleanse our database?
B2B data decays at roughly 30% per year. We recommend quarterly cleansing for active sales databases and monthly for high-volume outbound programs. We offer ongoing hygiene subscriptions for continuous maintenance.
What's your accuracy rate after cleansing?
We guarantee 95%+ deliverability on email addresses and 90%+ accuracy on firmographic fields (title, company, phone). Records that can't be verified are flagged, not guessed.
How is pricing structured for data cleansing?
Pricing is based on database size and the depth of cleansing required. We offer per-record pricing for one-time projects and discounted rates for volumes above 50,000 records. Contact us for a custom quote — there are no hidden fees.
Can I get a free sample cleanse before committing?
Yes. We offer a complimentary sample cleanse on up to 500 records so you can evaluate our accuracy, formatting, and turnaround before committing to a full project.
How do you protect our data during the cleansing process?
All data is transmitted via TLS encryption, processed in SOC 2-compliant infrastructure, and deleted from our systems within 30 days of delivery. We sign NDAs and DPAs on request and never share your data with third parties.
