Should you buy a B2B lead list?

Why do purchased lead lists perform poorly

Purchased lead lists perform poorly because they are assembled for a broad market, not for the accounts and roles you actually sell to. You pay for many names you would never have chosen.

They also age fast. People change jobs, companies merge and rebrand, and addresses close. A list has no way of telling you which rows went stale since it was compiled, and the same names may already be in the inboxes of every other buyer.

Is it legal to buy email lists

Buying a list is not illegal in itself in the UK or the EU, but using it lawfully is your job once you hold it. You become responsible for the personal data, for having a lawful basis to email each person and for telling them where you got their details by your first message.

In the UK, many people on consumer-style lists are individual subscribers under PECR and cannot be emailed for marketing without consent. If the seller cannot show how the data was collected and what people were told, you cannot show it either. This is general guidance, not legal advice; check your own position with a data protection adviser.

• Where did each record come from, and when was it last checked?
• Were the people told their details could be passed on for marketing?
• Does the list separate work addresses from personal ones?
• Has the same list been sold to others, and how often?

What does buying email lists do to your sender reputation

Buying email lists puts your sender reputation at risk, because mailbox providers judge your domain by bounces, complaints and whether anyone engages. A list full of stale or unexpected addresses hurts all three.

Many email sending platforms forbid purchased lists in their terms of use, and old lists can contain abandoned addresses that providers use to spot careless senders. The damage then reaches every email your team sends, not only the campaign.

Bought lists vs prospecting against your ICP

Prospecting against your ideal customer profile wins on fit and freshness; a bought list wins only on speed. When you search for the companies and roles you chose, every name has a reason to be there.

There is one fair use for a broad list: counting. Sizing a market or a territory needs company numbers, not emails, and nobody has to be contacted to do it.

What should you build instead of buying

Build a smaller list that you can explain line by line. Start from the customers you already win, then search outward for companies and people who look like them.

• Write down your ideal customer profile: industry, size, location and the roles that buy.
• Name the target accounts that match it.
• Find the people in those roles at each account.
• Check every work email before it goes into a send.
• Record where each contact came from, for your privacy notice.
