I will clean, dedupe and validate your hubspot contacts and import them safely
About this Gig
Bad contact data kills campaigns and wastes sales time. Ill clean, deduplicate and validate your HubSpot contact list so emails, phones, and company fields are standardized, duplicates removed, and imports are safe. Quick scans can show you the win immediately; full cleans include mapping, consent tagging, and import QA.
Process: you share an export (or grant read-access), I run a non-destructive scan showing duplicates, invalid emails, phone formats, and missing fields. After you review the report I clean and standardize entries, remove exact duplicates, flag likely merges, and prepare a safe import CSV (or perform the import with your permission). Delivery includes a before/after CSV preview and a 1-page summary of actions taken.
Perfect for migrations, list hygiene before campaigns, or one-off cleanups. Add the fast delivery audit to get a prioritized issues list in 24 hours. I never delete live data without your explicit approval and always provide a backup.

FAQ
Will you delete contacts?
No. Deletions are only performed after your explicit approval. I provide backups and a rollback CSV.
How do you identify duplicates?
Multiple rules: exact match, normalized email, phone match, and fuzzy name+company scoring for likely duplicates — I present merges for approval.
Can you add GDPR consent tagging?
Yes — I can add consent properties and map existing opt-ins into HubSpot fields as part of the Premium clean.
