What Data Cleansing Services delivers
A B2B database is a perishable asset. Roles change, companies rebrand, mailboxes are decommissioned, and roughly a third of every file silently rots over twelve months. The B2B Marketing Archives Data Cleansing service treats your marketing and CRM stores like a system that needs scheduled maintenance: we profile what's actually in there, flag what's stale, fix what can be saved, and remove what's beyond repair. Engagements scale from one-off pre-campaign scrubs on 10K-record segments up to multi-million-record warehouse cleanups, and every change applied to the file lands with a documented before/after trail your data stewards can audit.
- Duplicate resolution using both rule-based and probabilistic matching layers
- Cross-channel validation — email, phone and postal each checked independently
- Normalization of free-text fields: titles, industries, revenue tiers, regions
- Soft-delete recommendations on records that fail revival thresholds
- Built-in NCOA, DNC and global suppression-list enforcement
Where Data Cleansing fits in
Tightening list hygiene before a high-stakes outbound push
Untangling duplicates after migrating between CRM platforms
Trimming dead seats out of an over-provisioned MAP instance
Producing an auditable file for a GDPR or CCPA subject-rights response
What is Data Cleansing?
Data Cleansing is a structured pass over your existing records that finds the entries that are wrong, duplicated, outdated or incomplete and either repairs them or marks them for retirement. The B2B Marketing Archives approach blends automated rule engines for the predictable problems with human review on the edge cases — the ambiguous duplicates, the merged-company records, the title abbreviations no algorithm should be guessing at — so the file that ships back is one your team can defend.
How can data cleansing benefit your business?
The cost of a dirty database compounds quietly. Bounces train inbox providers to throttle you. Duplicates inflate the per-seat cost of every tool downstream. Inconsistent firmographic fields break segmentation rules nobody notices until the report is wrong. Cleansing puts those silent leaks back under control.
- Push bounce rates back toward inbox-friendly thresholds
- Shrink the contact count your MAP and CRM are actually billed against
- Make ABM scoring and segmentation honest by fixing the underlying fields
- Be ready when legal asks for proof of consent or erasure compliance

Questions about Data Cleansing Services
Do you sign DPAs, NDAs and security paperwork for Data Cleansing engagements?+
Yes. B2B Marketing Archives routinely signs mutual NDAs, Data Processing Agreements (GDPR Article 28-compliant), and customer security agreements before a data cleansing engagement begins. Standard documentation is available within one business day of request, and red-line review is supported. For enterprise procurement, SOC-2 attestation is shared under NDA.
How does Data Cleansing pricing compare to in-house implementation?+
Most teams underestimate the in-house cost of data cleansing work by 3-5x because of hidden infrastructure, ongoing maintenance and specialist-hiring overhead. Managed data cleansing pricing is structured to be competitive against the fully-loaded in-house cost — including the data-engineer time you'd otherwise dedicate to it — rather than against the headline software-license cost alone.
Who is my point of contact during a Data Cleansing engagement?+
Each data cleansing engagement has a named data strategist as the single point of contact end-to-end — from kickoff through delivery and post-delivery support. You don't route through a ticket queue or get bounced between roles. The strategist sits inside your engagement context and can speak to scope, status and methodology at any point.
What's the rollback / re-run policy if a Data Cleansing engagement output doesn't meet specs?+
If a data cleansing engagement output falls outside the agreed accuracy or completeness SLA, we re-run the affected portion at no additional cost. The remedy is in writing in the SOW. For systemic issues (methodology mismatch with the input data), the data cleansing engagement is re-scoped and re-quoted before the re-run rather than rushed.
What does the onboarding process look like for the Data Cleansing file?+
Onboarding for the data cleansing file typically runs a single kickoff call (45–60 minutes) to lock the ICP filters, the sample criteria and the delivery format. We then ship a free sample inside 24 hours for sign-off, and only after you accept the sample do we curate and verify the full volume. You'll have one named data strategist owning your data cleansing engagement end-to-end — not a rotating support queue.
What is the bounce-rate guarantee on the Data Cleansing file?+
Every data cleansing engagement carries a written 5% hard-bounce cap. If bounces exceed that threshold within the first 30 days of delivery, the affected data cleansing records are replaced free of charge with no recurring fees, per-replacement charges or procedural hurdles. In practice the cap is rarely triggered because of the 90-day re-verification cycle and the live SMTP check, but the written remedy is in the contract.
How is the Data Cleansing engagement priced?+
Pricing for the data cleansing file is scoped per engagement and reflects volume, segmentation depth, verification tier and delivery model. There are no per-seat platform fees and no recurring license charges attached to the data cleansing data itself — you pay once for the records and services in scope. For a written quote tailored to your ICP and volume target, contact B2B Marketing Archives directly; quotes typically return inside one business day.
