The Dirty Secret of Purchased Leads
If you buy leads in home services, insurance, legal, or solar, you already suspect this: some slice of every batch you pay for was never going to answer the phone. Recycled contacts sold to four of your competitors last month. Typos that make the email undeliverable. Entries that a form-filling script invented from a name generator and a zip code.
Vendors are not necessarily lying to you. Many of them aggregate from affiliates who get paid per lead, and pay-per-lead affiliate programs attract exactly the kind of people who automate fake submissions. The junk flows downhill and lands in your CRM with your money attached.
Most Contracts Already Promise You Refunds
Here is the part most buyers never use. Almost every lead purchase agreement has a return clause: invalid contact information, duplicates, out-of-area, wrong service type. The vendor honors returns because they have to, but the burden of proof sits with you, and proving a lead is junk one phone call at a time costs more than the refund is worth.
That math flips the moment you can check the whole list at once. If you can show that 62 of 400 leads had emails that cannot receive mail, phone numbers that fail validation, or contact details that match known disposable services, that is not an argument. That is a spreadsheet the vendor's own returns process accepts.
How to Audit a List in Five Minutes
Export the batch to CSV with at least an email column, plus name and phone if you have them. Run it through a scoring tool before anyone works it. We built a free one for exactly this: upload the file at trafficvalidator.com/tools/lead-audit and it checks every row and tells you how many look fake, questionable, or real, with no signup.
Read the results the way a returns department would. Undeliverable email means the contact cannot be reached as sold. A disposable domain means the person actively avoided giving a real address. Contact details that look generated mean nobody exists at all. All three are return-eligible in most agreements.
Make It a Habit, Not a One-Off
The teams that get the most out of this audit every batch on arrival, before it hits the dialer. Two things happen. The refund requests go out while the return window is still open, and the vendor learns you check. Vendors route their cleanest inventory to buyers who audit, the same way suppliers ship their best produce to the restaurant that inspects deliveries.
The second-order effect is bigger than the refunds. Your sales team stops burning hours on dead contacts, your speed-to-lead on real prospects improves because the queue is not clogged, and your cost per acquired customer drops without changing anything about your marketing.
