FAQs about buying leads

Still have questions about how to find leads? Let’s answer them. 👇

Where can I buy leads for my business?

To buy leads for your business, you can use:

  • Lead generation software (like Kaspr).
  • Mailing list providers.
  • Online advertising platforms (like Google Ads).
  • Freelance lead generation experts.


When buying leads, remember you’re still the expert on your company. Only high-quality, relevant, and legally sourced leads are useful. So make sure you do your due diligence about a company before you buy any leads.

How much do leads cost to buy?

The cost of buying leads will depend on:

  • The industry in question.
  • The quality of a lead.
  • The source of the lead.
  • The number of leads needed.


Lead prices can range from a few cents to several dollars per lead. High-quality and exclusive leads tend to be more expensive. Particularly in industries with high competition or specialized niches.


It’s important to note that while buying leads can be an effective way to get customers, the quality and conversion rates of leads vary. Check the cost-effectiveness and potential return on investment of other marketing costs before purchasing leads. You can also keep track of how well they perform over time.

What are the legal considerations when buying leads?

When buying leads, it’s important to think about legal considerations like:

  • Data protection and privacy laws.
  • Consent and opt-in processes.
  • Anti-spam laws.
  • Do-not-call lists.


When it comes to data protection, in the EU there’s GDPR, and in California there’s CCPA. In the US, there’s also the CAN-SPAM Act, a law that gives recipients the right to have you stop emailing them. Be aware that it doesn’t just apply to bulk emails, but to individual emails as well.


You may want to consult with legal professionals to understand how these laws can impact your outbound marketing tactics.

How to evaluate the quality of leads before purchasing?

To evaluate lead quality, first define your ideal customer profile so you know what you’re looking for. Choose a lead provider that verifies their data. It’s also worth considering a platform with business intelligence data that will help you identify warm leads.


Try a lead scoring system on a small sample of leads before committing to a larger purchase.


Consider factors like:

  • Leads per month.
  • Target market relevance.
  • High-quality leads.
  • Low-quality leads.


Kaspr’s free version would be a great way of starting this process and finding the leads of your dreams!
