Most cleaning projects fall into one of four jobs. Each has its own failure modes, and we handle all four routinely.
Marketing lists decay. Addresses go stale, duplicates creep in from multiple sign-up forms, and invalid entries drag down deliverability. We verify each address, remove duplicates and dead entries, and flag records missing the consent fields GDPR expects.
UK addresses arrive in every format imaginable. We validate postcodes, standardise addresses to Royal Mail PAF conventions, and fix the casing, spacing and county inconsistencies that break mailing runs and territory reports.
Donor and supporter databases carry years of accumulated inconsistency: lapsed contacts, duplicate households, gift-aid records with missing fields. We deduplicate households, refresh contact records, and check gift-aid and consent fields rather than guessing at them, under GDPR throughout.
Migrating a CRM with dirty data just moves the problem. We deduplicate, standardise and validate your records before import, so the new system starts clean rather than inheriting a decade of drift.
