Cold calling lists are indispensable resources for SDRs conducting sales outreach. B2B companies compile cold calling lists to target high-quality prospects with the greatest potential for conversion.

Elements of a Cold Calling List

A comprehensive B2B cold calling list should contain detailed information about prospects and their companies. Remember, a prospect list is only as valuable as it is accurate and complete.

Be sure to include the following components in your cold calling lists:

  • Prospect Name 
  • Job Title/Role 
  • Company 
  • Phone Number
  • Email Address
  • Industry
  • Company Size
  • Other proprietary data

Some information, such as the prospect’s name, phone number, role, and company are the most important details for your list. However, additional information such as employee headcount helps you customize your campaigns and follow up with leads effectively.

How to Acquire Cold Call Lists

Businesses seeking cold calling lists have two options: create their own or purchase from data providers.

Manually building a list 

B2B companies can research their target market and develop their own lists using sources such as social media, business directories, and search engines. Artificial intelligence software can help by crawling the internet and extracting relevant contact information.

List building is an ongoing process that involves organizing and segmenting prospects based on their buying potential. This qualification helps focus cold calling efforts and allocate resources efficiently.

Manually building a cold calling list can be cost-effective, but it’s also time-consuming, as it may take weeks to generate a robust list.

Buying from list providers

A faster alternative is to buy lists from data providers, who compile B2B contacts across various industries. In this case, find reputable data brokers, select a tailored list for your campaign, and integrate it into your CRM for success.

The Dangers of Buying Cold Call Lists

Although purchasing cold call lists saves time and requires less effort compared to building a list from scratch, this approach has several drawbacks you should be aware of.

Poor data quality

cold calling lists 2023

Many list providers don’t update or review their contact data, leading to outdated information and wasted time and money. Research shows that 72% of wasted cold calling time is due to inaccurate list data.1

High cost

Cold calling lists can be expensive, with subscription-based plans ranging from a few hundred to several thousand dollars per month. This can be a significant investment for small businesses, especially considering cold calling’s low conversion rates.

Low conversion rates

Leads from purchased lists may not be a good fit for your product or service, resulting in lower conversion rates compared to organically generated leads.

Privacy and legal issues

Data providers must comply with data privacy regulations, such as the California Consumer Privacy Act (CCPA). Qcquiring lists from non-compliant vendors exposes your company to legal liability and potential reputation damage.

Reputable Data Brokers

Despite the issues discussed above, purchasing a cold calling list from a third party can be a great option for your business — if you go through a reputable broker. To keep you on the straight and narrow, here’s an overview of some popular B2B data providers. 


SalesIntel provides company information for cold calling campaigns. They combine human and AI verification for their lists and offer extensive data coverage, allowing organizations to craft targeted and personalized outreach efforts.

Strategies for Building a Powerful Cold Calling List

To produce a powerful list, your business needs a clear ideal customer profile (ICP). Identify the key characteristics of your most valuable clients to focus your sales and marketing efforts.

Your ICP serves as a blueprint for the prospects most likely to become clients, guiding your efforts to attract them. Analyze your current customers, considering demographic and firmographic information, along with sales patterns, to identify trends and signals for promising prospects.

Leverage content marketing

Create valuable content for your target audience to pinpoint relevant prospects for your cold calling list. Demonstrate your expertise and industry knowledge while warming potential leads through content like eBooks, guides, white papers, webinars, and blog posts with contact forms. Prospects interacting with your content indicate interest in your company and are ideal additions to your cold call list. Identify high-quality prospects by monitoring metrics such as downloads, shares, and email subscriptions.

Grow Your Network

Attending industry events and joining trade associations are valuable ways to connect with prospective customers. These activities help validate your product or service and strengthen your business’s credibility. Networking facilitates introductions that serve as the foundation for building rapport during a cold call. Personal and professional connections uncover valuable information about your prospects, allowing you to customize your approach and increase the likelihood of successful outreach.

Update Your List Regularly

Contact information in the B2B space can become outdated quickly, so it’s essential to update your cold calling list regularly. This practice ensures you’re working with accurate information, contributing to cold calling success. Regular checks reduce time wasted on incorrect contacts and increase response rates.


How long does it take to develop a successful cold call list?

The time required to compile a robust cold calling list depends on the desired list size, target audience, data sources, and research methods.

Larger lists and niche audiences take longer. High-quality data sources save time but may require a significant monetary investment, while low-cost sources demand more time for validation. Adopting specialized tools, software, or professional services can speed up the process but will also incur additional costs. 

How do I verify the authenticity of a data broker?

Conduct thorough research on the company’s background and reputation. You can request sample lists to check their quality, accuracy, and alignment with your target audience. Inquire about data sourcing methods and how the broker maintains and updates their lists. 

Look up customer satisfaction and social proof on review sites and evaluate the broker’s customer support, responsiveness, and professionalism. Compare pricing with industry standards and competitors, and look for guarantees or refunds if the data doesn’t meet quality standards.
