Buying a B2B prospect list: what you actually get
A bought list is a photo taken on a given day, sorted on a criterion that never says whether the person needs you. Here is what you pay for, and what it costs after.
Buying a list is tempting for one simple reason: it is the only way to have a thousand names this afternoon. Everything else takes weeks.
The problem is not that these lists are bad. It is that they answer a question you never asked: they tell you who exists, never who needs you.
What you are actually buying
A list is a photograph. Someone went through public profiles and company sites on a given date, kept the ones whose job title matched your request, and sold you the result.
Two things follow, and they explain the disappointing results. The photo starts ageing the moment it is taken. And the sorting criterion, the job title, is the weakest one there is: it says what someone does, not what is a problem for them right now.
A list tells you who exists. It never tells you who has a problem you can solve, nor when.
The three costs you do not see at purchase
- Decay. People change roles, companies, addresses. A list does not break at once, it degrades every month, and nobody warns you when it drops below the point of being useful.
- No intent. Nothing in the list says why to write to this person today rather than in a year. So you write the same thing to everyone, which is exactly what makes replies collapse.
- Responsibility. The moment you use that data you become the controller for how you use it: informing people, allowing them to object, being able to say where the data came from. The seller does not carry that for you.
In B2B, writing to someone about their professional role does not require prior consent in France. That does not remove the duty to inform them, nor to leave a simple way to object, in every message. A bought list gives you neither of those.
Bought list, built list
What a bought list gives you
- A thousand names, sorted on a job title
- No idea what any of them worries about
- One identical message for everyone
- An origin you cannot explain
What a built list gives you
- Fewer names, chosen on a situation
- A reason to write, specific to each
- Words taken from your own clients
- An origin you own and can justify
The test to run before sending anything
Take a row of your list at random and answer one question: why this person, and why today. If the answer is their job title, you do not have a reason to write, you have an address.
That test kills most bought lists in ten seconds, and it kills plenty of hand-built ones too. It does not say volume is useless; it says volume without a reason to write produces volume of silence.
What you already have, and it is better
Your calls hold the material no vendor can sell you: the situation your clients were in when they bought, what was blocking them, and the words they used to say it.
That is where real search criteria come from. Not job titles, but signals: a team that just grew, a tool someone announced dropping, a responsibility that changed. A list sorted on those is shorter, and every row carries its own reason to be contacted.
Criteria drawn from your calls, then the profiles that match
Meidly's prospect search builds your targeting criteria from what your clients say, then screens profiles against those criteria rather than against a job title.
Discover prospect search→When a bought list still makes sense
- To map a market you do not know yet, without writing to anyone.
- To check the size of a segment before investing time in it.
- To find specific companies you have already decided you care about.
In those three cases the list serves to understand, not to contact. That is the use where it is honest, and nobody sells it that way.
Frequently asked questions
Is buying a B2B prospect list legal?
Writing to someone about their professional role does not require prior consent in B2B in France. You must still inform them, say where the data came from, and leave a simple way to object in every message. By using the list you become the controller for how you use it.
Why does a bought list get so few replies?
Because it is sorted on the job title, which says what a person does and never what is a problem for them. Without a reason to write specific to each one, the message is the same for everyone, and that hurts reply rates far more than address quality does.
How fast does a list go stale?
It does not expire at once, it wears out continuously, at the pace of role and company changes. The decay is invisible: nothing warns you when the list drops below the point where it is still worth the time you spend on it.
How many prospects do you actually need?
Far fewer than people think, as long as every row carries a reason to be contacted. A short list where you can say why this person and why now beats a long one without that why, for a comparable amount of work.
