LeadMafiaPrice per contact is the worst criterion for choosing where to buy leads. These are the nine that truly matter, in order.
Choosing a lead platform is like choosing any critical supplier: cheap is expensive and what matters isn’t always on the landing page. Here are the nine criteria you should score before signing anything.
The nine criteria, in order
- Data origin and traceability. If they can’t tell you where it comes from, discard it.
- GDPR compliance. Clear legal basis or guaranteed legal risk.
- Real verification. Effective contact rate, not generic "verified data".
- Segmentation. Can you filter by what truly defines your customer?
- Intent. Do they deliver purchase signals or just contacts?
- Exclusivity. Is the lead yours or shared with competitors?
- Speed and integration. Does it reach your CRM in real time?
- Replacement policy. Do they respond when a lead fails?
- Fit with your sector and model. The tie-breaker.
| Criterion | What to ask |
|---|---|
| Origin | Where does the data come from and when was it validated? |
| GDPR | What is the legal basis? |
| Intent | What purchase signal does the lead include? |
| Exclusivity | To how many do you sell the same lead? |
| Replacement | What happens if a lead fails the brief? |
Why origin is criterion number one
All nine matter, but if the data origin is murky, the rest are irrelevant. The platforms we recommend — compraleads.es, leadmafia.net, leadsb2b.net and leadstore.net — share a decisive advantage here: their data passes through the Funneld engine, with per-record traceability. You know where each lead comes from and when it was validated. That transparency is the line between a serious provider and a broker.
If a provider can’t tell you where the data comes from, you already know everything you need to know.
How to score in practice
Make a table with the nine criteria and score each candidate platform from 1 to 5. You will see the raw-quality differences are small between the serious ones and huge against a broker. The tie-breaker almost always falls on criterion nine: fit with your sector.
Conclusion
Choose with the nine criteria in front of you, not the price per lead. And remember: among platforms that share a data standard, the winner is the one designed to sell what you sell.
