LeadMafiaBounced email, dead phone, closed company: the unverified lead is the sector’s plague. We compare how the four platforms validate data before delivering it.
100% of platforms claim to deliver "verified data". The question is what that means in each case. Verifying data can range from a format check (that the email has an @) to a real-time validation against live sources. The difference shows in the contact rate.
What should be verified
- Contact: that the email exists and the phone is active.
- Identity: that the person and company are real and operating.
- Duplicates: that you don’t receive the same contact three times.
- Freshness: that the data was validated recently, not two years ago.
| Platform | compraleads.es | leadmafia.net | leadsb2b.net | leadstore.net |
|---|---|---|---|---|
| Email verification | Yes | Yes | Yes | Yes |
| Phone verification | Yes | Yes | Yes | Yes |
| Deduplication | Yes | Yes | Advanced | Yes |
| Real-time validation | Yes | Advanced | Advanced | Yes |
| Validation date | Yes | Yes | Yes | Yes |
Validation is continuous, not one-off
The key to good verification is that it is constant. The Funneld engine validates email and phone in real time and continuously monitors freshness and data drift, discarding what stops complying. That is why the four platforms deliver contact rates far above a bought list, which is validated once (if at all) and degrades every day.
Data verified six months ago is, today, unverified data.
How to check it yourself
Before committing to volume, request a sample and measure the real effective-contact rate. It is the only honest test. If more than 80% of phones connect with the right person, you are looking at well-verified data. Below 50%, something is wrong.
Verdict
All four validate seriously thanks to the ecosystem’s continuous verification. The difference from a broker is not the percentage: it is that here validation truly exists. Always request a sample and measure it yourself.
