Verifying addresses without scaring the prospect
Where our data comes from, how we balance privacy with deliverability, and what to tell prospects when they ask.
Eventually a prospect will respond to your postcard with something like, "How did you find this address?" Here's the answer that lands well.
Where the data actually comes from
We don't buy data brokers' people-files. We don't scrape voter rolls. The address you mailed came from one of four signal sources:
1. Their LinkedIn profile — explicit "based in {city}" + the company HQ.
2. Public property records — county-level ownership, only used when it cross-references to LinkedIn + business filings.
3. Business address from corporate registrations — the address on file with the state.
4. Postal deliverability checks — confirms the address actually exists and accepts mail.
What to say when they ask
"Public business records + LinkedIn. Same way you'd find someone on Google."
That's it. Don't get cute. The truth is the data is all public and they shouldn't be alarmed. Pretending you have a magic system is what makes people nervous.
Heads up
Never name the prospect's home address back to them in a reply. Even if you mailed to it. They asked because it felt invasive — don't double down.
Edge cases that need care
Don't postcard people from regulated industries (healthcare, finance) at their home address without explicit cover from their employer or a clear opt-in. The legal sensitivity isn't worth it.
Don't postcard executives at company-owned residences (rare, but happens) — those addresses are often listed on board filings and end up in our index. Flag them manually.
