What is a Prospecting List?

What is prospecting list?

A prospecting list is a curated list of potential customers or leads who have expressed an interest in your products and services. They should ideally also be a good fit with your ideal customer profiles.  

A prospecting list is the starting point of all your sales and marketing efforts, informing your strategy from segmentation, targeting and personalization to engagement, conversion and customer service. 

Prospect lists include contact and company insights that let your sales team interact efficiently with potential customers.

5 Strategies to Build Optimized B2B Prospecting Lists

Creating a prospecting list isn’t a random activity. Any prospecting list should be rooted in market research. It is a strategic process that should follow tried and tested methods.  

Before we get into the list-building process, here are 5 strategies you should consider first. 

1. Build Ideal Customer Profiles (ICP)

An Ideal Customer Profile is a detailed characterization of your ideal customer. It includes information that gives you a clear idea of who to prospect, such as:

An ICP should be the first step in any outreach. Following this profiling, segment your ideal customers into clearly defined groups. Each group should have a different targeting and personalization strategy.  

The more specific your ICP, the more targeted your prospecting can be.  

2. Enrich Your Prospecting List

Lead enrichment is the process of enhancing the quality of your prospecting list. A prospecting list is the backbone on which you can flesh out additional information to help qualify your leads further.  

Lead enrichment consists of several steps. The more steps you follow, the better your list quality is.  

Here are 7 steps in lead enrichment that are essential for creating actionable prospecting lists.

Picture of Standardization

Format your prospecting list into a standard, consistent structure. The most common structure is a tabular spreadsheet containing data attributes and corresponding values.

Define the attributes you need (e.g. job title, email, phone number, company name, SIC code, industry, etc.) and standardize them across your prospecting list.

Picture of Validation

Data validation is the process of checking the data you collected for redundancies, errors, inconsistencies, missing values and then verifying and cross-verifying them for accuracy.

This includes email verification, phone number and address validation, and verification of company information.

Picture of Enhancement

Data enhancement is the process of adding additional relevant information to your prospecting lists or profiles.

This information includes specific details like social media profiles, behavioral information, NPI numbers, industry codes, company’s annual revenues, employee size, organization structure, and more.

Picture of Deduplication

Identify and correct duplicate entries in your prospecting list to eliminate redundancies using deduplication tools like Microsoft Excel, Dedupe.ly, Dedupe.io, RingLead, Openprise, and HubSpot.

Picture of Segmentation

Using common characteristics, segment your list into more specific, separate lists. You can segment your list by industry, technologies used, location, lead source, and other relevant criteria.

Segmentation helps you target better by focusing on this common criterion to prospect.

Picture of Lead Scoring

Build a matrix of factors like engagement, quality of fit with your ICP and intent signals to assign a score to each lead in your prospecting list.

Lead scoring helps you prioritize your sales effort and sales follow-ups for more promising leads.

Picture of Updates

Establish a monthly or quarterly process for updating the contact and company information in your list. Contact lists decay at the rate of 25% a year.

Maintain up-to-date lists for consistent data accuracy and email deliverability rates.

3. Use CRM and Sales Automation Software

Customer relationship management and sales automation software provide a single, seamless platform for organizing, managing and tracking your interaction with prospects.

4. Tap into Social Media and Online Networks

Connect personally with potential leads on LinkedIn and Instagram.  

Build your own brand voice for each social media platform and tap into professional online networks to scout people and companies that fit your ideal buyer personas.  

This is what you can do with social media platforms for instant lead generation:

Brand image

Create a brand persona and brand voice to build interest and attract the likes.  

Skip the formalities! Be confident with your brand voice. Whether it’s business casual or funky, stay true to who you are and leave a lasting impression with a creative yet balanced approach.  

Talk about your product!

And no, this doesn’t have to be shameless self-promotion and crazy offers.  

Talk about how to use your product and how it provides extra value over similar products. Give steps, tips, techniques, tutorials. Don’t gatekeep any know-how. 


Join in on the big conversations happening on LinkedIn or any other platform.  

Collaborate with voices that have some authority in your field and publish that reel/podcast. Hold a conversation on a LinkedIn comment section. Join groups, events, webinars. 


Always encourage your connections and audiences to join your email list or subscribe to your newsletter for tips and updates. Tell them exactly what they’ll be getting. Give them a sneak peek. As I said before, do not gatekeep valuable information.  

5. Regularly Update and Clean Your List

Contact information decays over time. Outdated data impacts your campaign KPIs and email metrics significantly, bringing down your deliverability rates and damaging your domain reputation.  

For your prospecting lists to result in higher conversions, you must regularly validate, clean and update them. It is recommended to update your database within 90 days and preferably within a month.  

The process of monthly enrichment includes all the steps of lead enrichment, from correcting inaccuracies and removing duplicates to updating and verifying new information like updated companies, emails and addresses.  

This is a tedious task when done alone with each step requiring several different tools, most of which are expensive.  

In the following sections, I’ll show you how you can use ReachStream, a free list-building and sales prospecting tool (with affordable premium and custom API plans as well) to build, enrich and maintain prospecting lists (or existing databases).

Frequently Asked Questions

How can I measure the success of my prospecting list?

Key performance indicators (KPIs) such as conversion rates, lead quality and engagement metrics can help you measure the success of your prospecting list. Regularly analyze and tweak your approach to improve the effectiveness of your lists.  

Personalization is key. Tailor your communication to specific needs and pain points of your prospects at the ground level. Utilize multiple channels and targeted content to create a well-rounded engagement strategy first.  

Ensure that your data collection and management process align with relevant data protection regulations such as GDPR. Consent is key. Ask for opt-in consent before adding anyone to your list. We recommend using ReachStream as it contains pre-validated databases which are compliant with GDPR, CCPA, ACMA, EDPS, and CAN-SPAM act. ReachStream’s contacts are also 100% opt-in consented.

Lists should contain more than contact information. They should have comprehensive and relevant details about the prospect, their company, industry, demographics, technographics, location, and contact information.
