The warning signs that separate a real lead supplier from a lead mill, the questions that surface them in one phone call, and what a good answer sounds like.
Choosing a lead supplier badly is expensive in a way that shows up slowly. The invoice arrives on day one and the damage appears over the following quarter, by which point it is difficult to separate a bad supplier from a bad month.
These are the signs that are visible on the first call, which is when it is still cheap to walk away.
This is the question that sorts the category. Ask for the live URL of the page the enquiry was submitted on. Not a description, not a screenshot, the URL.
An operator who owns their consumer brand sends it in the same reply, because it is their own website. An operator buying enquiries from an affiliate network often genuinely cannot, because the traffic passed through hands they do not control. That answer tells you more about what you are buying than any spec sheet will.
Why the page matters more than the record: The landing page sets the consumer expectation you inherit. A page promising a comparison produces someone expecting a comparison. A page implying an entitlement produces someone expecting money. Both produce records that look identical in a CRM and behave completely differently on the phone.
Verification is where the gap between the word and the practice is widest, because four very different checks are all sold under the same label.
| What they say | What to ask | What a good answer sounds like |
|---|---|---|
| "All leads are verified" | Verified how, and at what point? | An SMS code completed inside the form flow, before the record exists |
| "We validate every number" | Validate the format, or the person? | The consumer typed a code we sent to that handset |
| "Quality checked by our team" | Checked against what criteria? | A named, written standard you can read |
| "Verified within 24 hours" | So the record exists before verification? | Verification happens at submission, not afterwards |
The last row catches a common design. A supplier who verifies after the fact is selling you records that were created without verification and cleaned later, which is a different product from records that could not exist without it.
Exclusivity is routinely sold as a property and delivered as a window. Ask two questions: is this record sold to anyone else, and what happens to it after any exclusivity period ends?
A time-limited window means the record returns to a saleable pool when it expires. Nothing in the contract is breached, and the consumer receives their fifth call four months after asking one question, with your firm among the callers.
A replacement guarantee is only as good as how quickly and how willingly it pays. The warning signs are structural rather than tonal.
| Red flag | Why it exists | What to ask for instead |
|---|---|---|
| A monthly cap on replacements | It bounds the supplier's exposure, not your risk | An uncapped policy tied to written criteria |
| A points or quota system | It rations a right you already paid for | A per-record claim with a stated turnaround |
| "Reviewed case by case" | Discretion sits entirely with the supplier | Criteria defined in advance, agreed by you |
| A short claim window | Many invalid records surface after several attempts | A window that allows a full six-attempt cadence |
| Credit toward future purchases only | It locks you in rather than making you whole | A choice between credit and refund |
The claim window is the one brokers most often miss. If invalidity can only be claimed within 48 hours, and a full contact cadence runs a fortnight, the policy expires before you can know whether the record was any good.
Verify the counterparty before you verify anything about the product. Both markets have free public registers, and the check takes minutes.
An operator who is reluctant to name the contracting entity is answering the question. There is no legitimate reason for that reluctance and several illegitimate ones.
These are individually weak and collectively decisive.
How Lead Foundry answers this: Our enquiries come from QuoteHub, which we own. You can check the entity on the New Zealand Business Number register. Verification happens inside the form flow, exclusivity has no expiry, and you set the criteria a lead must meet before supply begins.
Specific, and slightly boring. A supplier running a clean operation answers factual questions with facts, sends artefacts rather than assurances, and is comfortable with a small trial because they expect it to go well.
A supplier running a lead mill answers with adjectives, redirects toward price, and treats a request for the source URL as an unusual thing to want.
The clearest are an inability to name the domain the enquiry came from, vague verification language that never specifies which test runs or when, exclusivity expressed as a time-limited window rather than a permanent term, a replacement policy with caps or quotas, and delivery only by email or CSV. Pressure to commit to volume before a trial is a reliable accompaniment to all of them.
In New Zealand, look up the entity on the New Zealand Business Number register and, where financial services are involved, the Financial Service Providers Register. In Australia, use ABN lookup and the relevant ASIC registers. Confirm the entity you checked is the one that will appear on your invoice, and ask for a named person you can reach when something goes wrong.
Criteria for invalidity defined in writing and agreed before supply starts, a per-record claim process with a stated turnaround, no cap or quota on the number of claims, a claim window long enough to complete a full six-attempt contact cadence, and a choice between credit and refund rather than credit only.
Yes, and it is the single most informative question available on a first call. An operator who owns the consumer brand sends the live URL immediately. One buying enquiries from an affiliate network frequently cannot produce it, which answers a much larger question about who controls the quality of what you are buying.
