About this Gig
**Your contact list is only as good as its data. I turn messy, duplicate-filled contact exports into a clean database your team can actually use.**
What I fix:
Duplicate contacts (matched smartly by email, phone, or name not just exact matches)
Inconsistent names (ALL CAPS, lowercase, "Dr./Mr." prefixes standardized)
Invalid or malformed email addresses flagged or removed
Phone numbers standardized to one consistent format
First/last names split into proper columns
Multiple exports (CRM, newsletter tool, spreadsheets) merged into one master list
What you get:
A clean, deduplicated contact file ready to import into any CRM or email tool (Mailchimp, HubSpot, Salesforce, etc.)
A summary showing how many duplicates/invalid entries were removed
Optional "removed entries" sheet so nothing is lost silently
**Message me your approximate contact count and I'll confirm the right package before you order.**
All contact data is strictly confidential and permanently deleted after delivery.

FAQ
Do you verify whether emails are deliverable?
I flag invalid formats and obvious fakes. Live deliverability verification (SMTP checking) is a different service — ask me and I'll advise.
My contacts are in different formats from different tools. Is that okay?
Yes — merging mismatched exports into one consistent database is exactly what this gig is for.
Will I lose any data?
No. Anything removed is preserved in a separate "removed" sheet in the delivered file so you can review it.
Is my customer data safe?
Yes. Files are used solely for your order, never shared, and deleted after the order closes.
