Red flags that a B2B lead vendor sells scraped lists

Short answer: the main red flag is a vendor that cannot tell you where a contact came from, when and how, or whether the person agreed to be contacted. Other signs are lists sold in bulk, no replacement for bad records, and a price that ignores any qualification. You cannot prove scraping from outside, so ask for records.

The test is evidence on a sample record, not a promise in a sales email.

How can you tell what a vendor is really selling?

Ask for one sample record and the evidence behind it. On the sample record, check four things: is there a stated need, a consent record, a date and a named source? If any is missing, ask the vendor to supply it. You cannot tell by looking at a spreadsheet, so the test is whether the vendor can show the history.

We cannot say how any other vendor sources data, and this guide does not accuse anyone. It lists questions that separate a vendor who holds the evidence from one who does not.

Which warning signs should you look for?

Use the table as a checklist. A single sign proves nothing, and several together deserve caution.

Ask for the answers in writing. A vendor who is happy to explain its process will usually be happy to write it down.

Why does consent matter for B2B contacts?

Because the way you contact someone depends on whether they asked to hear from you. For commercial electronic messages in Canada, section 6(1) of the anti-spam statute, published at laws-lois.justice.gc.ca and read on October 23, 2026, prohibits sending one unless the recipient “has consented to receiving it, whether the consent is express or implied”. Whether a given contact meets that test is a question for your compliance officer, who should review the vendor’s consent evidence. This guide is not legal advice.

Rules in other countries differ, and we make no claim about them here. Ask your adviser which apply to the people you plan to contact.

What should the contract say?

Put the process and the remedy in writing: how a lead is sourced, what makes it valid, the evidence you receive, the window for disputing a lead and what replaces a bad one. Under Vivin’s lead agreement, a delivered lead can be disputed within 5 business days of delivery under the written criteria, and a lead that failed a gate is replaced with one that passes. The lead agreement has the wording.

Also ask who owns the list at the end, and what happens to a contact who opts out. For the wider contract checklist, read hidden costs in lead generation contracts.

How does Vivin handle this?

Vivin Sales charges USD $15 to $500 per accepted lead across its markets. Each lead is exclusive and never resold, and a lead that is off-criteria is replaced. There is no setup fee. Every fee is listed in your written quote before you sign. Vivin works from the consent the person gave when they asked to be contacted and records when and where they gave it. The sample lead shows an example record structure.

What can you do before you buy?

Run a small test. Ask for a short batch, check every record against the evidence you were promised, count the ones that fail and see how the vendor handles them. How to run a small pilot with a B2B lead provider sets out the steps. If the vendor refuses a sample or a written replacement rule, treat that as your answer.

What should you do if a vendor will not answer?

Treat silence as information and stop before you pay. You do not need to prove anything about the vendor; you only need to decide whether you can defend the purchase. If your compliance officer asks where a contact came from and you cannot say, the lead is a liability whatever it cost.

Keep the correspondence. A vendor who answers clearly in writing has given you something to rely on, and a vendor who will not has told you what you needed to know. Move to a provider who can show a record for each lead.

Frequently asked questions

Can I prove a list was scraped?

Not reliably from outside. You can ask for the source and consent record of a sample lead and judge the answer.

Is a cheap list a sign of scraping?

Not by itself. Price is one input, so check the evidence and the replacement terms.

What evidence should a lead include?

A date, the source, what the person asked for and the consent they gave, plus the contact fields you agreed.

Does Vivin resell its leads?

No. Each lead is exclusive and never resold, and a lead that is off-criteria is replaced.
