What Is a Sales Lead List?

A sales lead list is a database of individuals who have shown interest in your product/service offering and have met your Ideal Customer Profile (ICP) criteria.

Your lead list provides your sales team with a list of individuals they can contact to move them down a sales funnel and convert them into loyal customers.

Where do you get your sales leads from?

Your sales leads usually come from both your inbound and outbound efforts — whether it’s someone signing up for your newsletter or being reached out to via cold emails and targeted campaigns.

With the basics out of the way, let me show you some of the minimum, must-have information in your sales lead list.

Don’t get confused:
A sales lead list is quite different from a sales prospect list, which contains a list of potential clients with whom you’ve not established initial contact.

10 Things You Must Include In Your Sales Lead List

The first step in building a lead list is knowing what to include.

Trust me, as someone who has built several sales lead lists from scratch, this step is as crucial as building the list itself!

Once you know what to include, building the lead list becomes very simple.

Let’s check out some of the crucial information that your sales lead list must include:

1. Contact Information

Email addresses, direct dials, mobile numbers, and LinkedIn profile link of your leads will help you keep in touch with them throughout the sales journey.

2. Job Title and Description

These firmographic details will help you understand how closely your leads align with your buyer personas.

After all, you don’t want to contact someone without knowing whether they have the decision-making authority within the company you’re targeting.

3. Demographic Information

The age, location, and education of your leads will aid you in personalizing your sales pitch. It can also tell you which sales strategy will likely work with them. 

4. Company Information

Name, industry, revenue, employee strength, location, etc., of the leads.

All this will help you in two ways: one, to check if they match your ICP and score them, and two, to personalize your pitch. 

5. Pain Points

A list of your leads’ pain points will help you understand how you can position yourself as a solution provider.

6. Intent Data

This includes your prospects’ recent social media posts, the latest news, funding information, and expansion announcements. It will tell you the perfect time to target your leads with a tailored pitch.

7. Lead Source

How did you come across the lead? Your lead source can be:

• Your website visitor log
• An e-book or white paper download
• A social media interaction
• An email exchange

This information will inform your future lead generation strategy and give you insight into your leads’ purchasing behavior.

8. Lead Score

The lead score tells you how interested your leads are in your product/service and how likely you are to convert them. 

9. Interaction History

I highly recommend keeping a history of conversations with your leads. These could be touchpoints including but not limited to: 

• Emails
• LinkedIn messages
• Conference interactions
• Product demos

Keep in mind that there’s an important difference between a lead source and interaction history. The lead source is the starting point, whereas the interaction history is a comprehensive record of your interactions with the lead.

10. Additional Comments

In this section, I suggest you include your leads’ specific interests, work experience, or other relevant information that can help you tailor your sales pitch.

Alright, now that we know what to include in our sales lead list, let’s find out how to build one…

How to Build a B2B Sales Lead List in 7 Steps

From the hundreds of sales lead lists I have come across, I’ve noticed that all of them contain three types of people:

• Those on a sales prospect list who have responded positively to your outreach.
• People who have exhibited interest in your product/service.
• Prospects you’re already in contact with through different touchpoints.

In other words, building a sales lead list involves understanding your product/service, contacting prospects, and keeping track of existing interactions.

Here are the 7 steps you should follow every time you want to make an actionable lead list:

1. Know Your Offer Inside Out
2. Create an ICP and Buyer Persona
3. Explore LinkedIn
4. Use a B2B Database Platform
5. Inbound and Outbound Marketing to Bring in Leads
6. Gather All Your Leads and Score Them
7. Finalize Your Sales Lead List

1. Know Your Offer Inside Out

The first and foremost part of any sales activity is knowing how your product/service can help your ideal customers achieve their goals and objectives.

To do this, I suggest you first identify the pain points that it solves.

Next, determine the standout features of your product that your competitors lack.

Lastly, think about the value your solution brings to different industries, users, or enterprise operations.

All these will give you ideas and insights on how you can position your offering as an ideal solution in front of your prospects.

2. Create an ICP and Buyer Persona

The next crucial step is sketching who your ideal customer would be, this will help you streamline your lead generation efforts.

For this, you will need your Ideal Customer Profile and Buyer Persona.

The Ideal Customer Profile (ICP) refers to a fictional description of the ideal company you would like to have as your customers, whereas the buyer persona describes the decision-maker in those companies.

The best leads will align closely with your ICP and buyer persona. Plus, I’ve noticed that if your ICP and buyer person are clearly defined, making a sales lead list becomes a breeze.

3. Explore LinkedIn

Now, it’s time to find companies that match your ICP and prospects that align with your buyer personas.

I suggest you start searching LinkedIn as, according to many B2B professionals, LinkedIn ranks first for building and nurturing corporate social connections.

Filter out companies who match your ICP and then find decision-makers you can reach out to.

It can be a time-consuming process, if you want a hassle-free method you should take a look at the next step.

4. Use a B2B Database Platform

While LinkedIn is great for finding individual leads, it can be a hassle for bulk lead/prospect finding.

That’s where dedicated B2B database platforms come into the picture.

These platforms usually have vast amounts of information about people from the B2B space, including their contact details, job titles, company names, industry, etc.

You can use the advanced search filters to find and filter companies and prospects that match your ICP and Buyer Persona criteria.

Pro Tip:
If you’re looking for a lead finder tool to use, I suggest you pick one that integrates lead generation with outreach. This will help you streamline your sales pipeline. 

5. Inbound and Outbound Marketing to Bring in Leads

An important part of building a sales lead list is getting your prospects interested in your products.

There are several lead generation strategies you can use to accomplish this objective. 

If you want to build authority and credibility through content and generate leads passively, I’d suggest you go for inbound strategies like content marketing, SEO, social media marketing, etc.

Or, you can use outbound marketing strategies like cold emails, cold calls, and targeted advertising to proactively reach out to potential leads.

Personally, I’d recommend you take a combined approach, mix inbound and outbound strategies to attract leads passively while actively pursuing high-value prospects.

6. Gather All Your Leads and Score Them

After initiating marketing campaigns, it’s time to gather your leads. I suggest you maintain an Excel sheet or use CRM software like Zoho, HubSpot, or Pipedrive. 

There are two ways in which you can score your leads:

1. Simple lead scoring: You can assign custom headings to different leads based on what stage of the sales funnel they have reached.
2. Numerical lead scoring: You can develop custom criteria by assigning scores to leads based on how closely they exhibit product-market fit, their pain points, the lead source, and other factors you want to prioritize (industry, company size or employee strength).

My suggestion:
Simple lead scoring works well if you’re dealing with a limited number of leads. For bulk leads, I recommend you go for numerical lead scoring.

7. Finalize Your Sales Lead List

And now, we get to the final stage of our lead list-building exercise.

If you’ve followed the steps we’ve discussed thus far, you’ve already done the hard part!

Now, it’s time to just sharpen your list and clean it up for your sales team to get started.

My suggestion:
When you’re finalizing your lead list, work closely with your marketing and sales team.

Think about your priorities: do you want to target the most valuable leads first or start with the hottest leads and build up your sales campaign?

You should also consider your company’s track record in converting different kinds of leads to determine which ones to prioritize and which ones to save for a rainy day…

Bonus Tips: When to Add a Person to Your Lead List

Getting started with building a sales lead list can be very challenging. 

So, I thought I would put together a list of scenarios under which you should add someone to your lead list. 

In my experience, the following scenarios indicate interest, product-market fit, and a history of prior contact between you and your prospect:

• They have visited your website more than once in one week and have shown explicit interest in what you have to offer.
• They have downloaded a whitepaper or filled out an interest form on your website.
• They have participated in a webinar you hosted.
• They have recently interacted with your company’s social media posts.
• They have responded positively to your outbound sales efforts.

If one of your prospects meets any of the criteria we’ve discussed above, you should definitely add them to your lead list.
