The Challenge: 173 Agents, Zero Room for Bad Data
When our client came to us, they had a spreadsheet of 173 real estate agents and a pressing need to reach them. The problem was that the contact details on hand were incomplete, unverified, and scattered. Email addresses were missing for many entries, phone numbers hadn't been confirmed as active, and website URLs had never been checked for validity.
At this scale, bad data is not a minor inconvenience — it's a campaign killer. Sending outreach to dead emails or wrong numbers erodes deliverability, wastes effort, and delays results. The client needed someone to get it right the first time.
Our Approach: Structured Research and Individual Verification
Helion360 started by auditing the existing spreadsheet to identify what was usable and what needed to be sourced entirely from scratch. We then built a systematic research process, pulling contact data from agent websites, regional real estate directories, brokerage pages, and verified professional listings.
Each contact point was treated as its own verification task. Websites were tested to confirm they were live. Phone numbers were cross-checked against official agent profiles. Email addresses were matched against the agents' own web presence wherever possible. Nothing was entered into the final file unless it had been confirmed as accurate and current.
The output was a clean, consistently formatted spreadsheet — organized to be immediately usable in outreach tools or importable directly into a CRM without additional cleaning.
What We Delivered
The completed database covered all 173 real estate agents, with each record containing a verified email address, active phone number, and working website URL. The file was delivered within the agreed timeline, formatted cleanly, and required no further processing on the client's end.
More importantly, the client could move into their outreach phase with confidence. The groundwork had been laid accurately, and they weren't starting a campaign on guesswork.
