Key takeaways
- A record without a reachable phone number is a research note, not a lead.
- Freshness at the moment of delivery beats total database size every time.
- The replacement policy tells you more about a vendor than any accuracy percentage.
- Test with a small sample in your real segment before signing anything.
What a usable record actually contains
Full name, job title, company, company size and industry, a verified work email, and a mobile number or direct dial that reaches the person.
Anything less forces your rep to finish the research, which is the expensive part you were trying to buy away.
Watch for lists that carry a company switchboard in the phone column. Those numbers are technically valid and practically useless, because they put a rep in front of a gatekeeper whose job is to stop the call.
- Person: name, title, seniority, LinkedIn where available.
- Company: name, industry, employee range, location.
- Reach: verified work email plus mobile or direct dial.
- Provenance: where the record came from and when it was retrieved.
What a fair price per contact looks like
Between 8 and 30 cents per contact for a list with a verified email and a phone number, with the price falling as monthly volume rises.
Cheap bulk files priced in fractions of a cent are usually recycled scrapes with no verification, and they cost far more in wasted dial time than they save in data spend.
At the other end, enterprise platform contracts bundle a licence, seats and features you may never touch. If all you need is people to call, output pricing is the cleaner purchase.
| Monthly volume | Reasonable range per contact |
|---|---|
| Under 500 | 20¢ to 30¢ |
| 500 to 2,500 | 12¢ to 20¢ |
| 2,500 to 10,000 | 8¢ to 14¢ |
Six questions that expose a weak vendor
Ask these before money moves. Vague answers to any of them predict the problems you will have in month two.
- What share of delivered records carry a mobile or direct dial, not a switchboard?
- How close to delivery day is the data checked?
- Will the same person ever be delivered to me twice?
- What happens when a number is wrong, and what does it cost me?
- Can I see where each record came from?
- How do you handle opt-out requests, and how fast?
How to run a fair test
Take a small sample in your exact target segment, dial every record yourself, and score connect rate and fit rather than reading an accuracy claim.
Use one segment, not a broad request. A vendor asked for 'tech companies' will send you the easy middle of the market and you will learn nothing about your real segment.
Score three things: did the number reach the named person, was the person a genuine fit, and would you have found them yourself in a reasonable amount of time. The third one is what you are really paying for.
Frequently asked questions
Is buying B2B lead lists legal?
Business-to-business contact data can be supplied and used for legitimate business outreach in most markets, but you remain the caller and sender, so local calling registration, consent and opt-out rules are yours to follow.
How big should my first purchase be?
Start with the smallest monthly volume that keeps your reps busy, prove connect rate, then scale volume. Nobody regrets starting at 200 or 500 a month.
How do I avoid paying twice for the same contact?
Insist on deduplication across your entire account history, not just within a single delivery file.
