How to Build a Lead List for Your Nigerian SME in 5 Steps (Using LeadThur)

You have spent three hours scrolling through Instagram business pages, saving phone numbers from Google Maps, and cross-checking an outdated Yellow Pages PDF from 2019. The result is a spreadsheet with 400 names, a mix of disconnected lines, and a vague sense that you have been busy without being productive.

This is not a lead list. This is a graveyard of unverified contacts that will waste your airtime and burn your sender reputation.

Building a lead list is not a data collection exercise. It is a pipeline. You are not looking for anyone who might vaguely need your service. You are looking for a specific set of businesses that match a profile you can define, verify, and reach. The goal is not 4,000 contacts. The goal is 100 contacts who could genuinely buy from you this quarter.

Here is a five-step process to build that list, using LeadThur where it saves you the most time, and doing the manual work where it actually matters.

Step 1: Define Your Ideal Customer Profile (ICP) Before You Search

Most sales teams skip this step. They open a search tool, type a broad keyword like "logistics company in Lagos," and export 2,000 results. Then they spend weeks calling through them, discovering that a large majority are either the wrong size, the wrong industry, or simply not in a position to buy your product.

This is not an exaggeration. As LeadThur's own guide on building high-quality lead lists notes, a poorly defined lead list will leave you with a majority of contacts who will never buy from you. The problem is not the tool. The problem is the lack of a filter before the search begins.

Your ICP is not a vague statement like "businesses that need software." It is a specific set of attributes you can use to filter a database. Answer these five questions in writing:

• Industry: What sector do they operate in? Be specific. "Food processing" is better than "FMCG." "Private schools" is better than "education."
• Location: Which city, and more importantly, which part of the city? A logistics company in Apapa has different needs than one in Ikeja.
• Size: How many employees? What is their likely annual revenue? If you sell enterprise software, a 5-person boutique agency is not your target.
• Pain point: What specific problem do they have that your product solves? If you sell inventory management, you want businesses that have complained about stockouts or shrinkage.
• Trigger event: What has changed recently? A new branch opening, a funding round, or a new regulatory requirement can make a business more receptive to your pitch.

For a Nigerian SME context, add one more filter: payment behaviour. If you sell on a subscription model, you want businesses that have a history of paying for software or retainer services, not just one-off cash purchases. You can often spot this by looking at whether they already use tools like QuickBooks, Paystack, or a CRM.

Write this down. Keep it on your desk. If a prospect does not match at least four of these five criteria, they do not go on the list.

Step 2: Use LeadThur to Find the Raw Matches

Now that you have a defined ICP, you can use a tool to find businesses that match it. This is where LeadThur comes in. Its core capability is straightforward: you can search for local and niche businesses by query and location to build prospect lists.

This is not a magic wand. It is a filter. The quality of what you get out depends entirely on the quality of the query you put in.

Let us walk through a concrete example. Suppose you sell HR compliance software to Nigerian manufacturing companies with more than 50 employees. Your ICP is: manufacturing, Lagos (Ikeja and environs), 50+ staff, and a likely pain point around labour law compliance.

In LeadThur, you would not search for "manufacturing companies." That is too broad. You would search for specific sub-sectors: "food and beverage manufacturer," "plastic moulding company," "pharmaceutical manufacturer," "packaging company." Each of these is a distinct niche with distinct compliance needs.

For a deeper dive into how to structure these searches, including how to layer location filters for Lagos and Abuja, read our guide on using LeadThur's search filters to target high-value clients. The key principle is to run multiple smaller searches rather than one massive export.

Here is a practical tip: run ten searches with different niche keywords rather than one search with a broad term. You will get fewer duplicates and a higher concentration of relevant businesses. For example:

• "plastic bottle manufacturer Lagos"
• "sachet water producer Ikeja"
• "bakery equipment supplier Lagos"
• "catering company Victoria Island"

Each search gives you a focused set of businesses that share a common characteristic. That makes your outreach message easier to personalize later.

As you export results, do not export everything. Export the first 20 to 30 from each search that visually match your ICP based on their name and description. You are aiming for a raw pool of about 200 to 250 businesses. You will filter this down further in the next steps.

Step 3: Verify Everything (Data Decays Faster Than You Think)

Here is an uncomfortable truth: the contact information you just exported is already partially outdated. People change jobs. Phone numbers get disconnected. Business email addresses get abandoned when a company rebrands. This is not a flaw in LeadThur or any other tool. It is the nature of data.

If you skip verification, you will waste time calling dead numbers, and worse, you will send emails to inactive addresses. This damages your sender reputation. Internet service providers and email platforms track bounce rates. If you send to too many invalid addresses, your legitimate emails start landing in spam folders, even for prospects who want to hear from you.

Verification is not glamorous, but it is essential. Here is a simple three-step process:

1. Call the main line. Ask for the person you identified by name. If they are not there, ask for the correct contact. This takes 30 seconds per call and eliminates a significant portion of your dead leads.
2. Check the website. If the business has a website, look at their "Contact Us" page. Does the email address match what you have? Is there a newer phone number? Look at their recent news or blog posts. If they have not posted in two years, they may be struggling, which is a different kind of lead.
3. Use a free email verification tool. There are several free tools that will check if an email address is syntactically valid and whether the domain accepts mail. Run your list through one of these before you send anything.

This verification step is where you cut your list from 250 raw leads to about 150 verified ones. The ones you remove are not failures. They are time you have saved yourself from wasting later.

If you are working solo, this step will take a few hours. That is fine. It is an investment. A verified list of 150 contacts is worth more than an unverified list of 1,500.

Step 4: Enrich and Segment (This Is Where Personalization Starts)

You now have a list of verified businesses. But a list of names and phone numbers is not yet a list of prospects. It is a list of strangers. To turn them into prospects, you need to know something about each one that is relevant to your pitch.

This is called enrichment. It is manual work, and it is the step most sales teams skip because it is tedious. That is a mistake. A personalized email that references a business's recent post, a new product launch, or a specific challenge in their industry will get a response. A generic "Dear Sir/Madam" email gets deleted. The difference is not luck. It is the enrichment you did before you hit send.

For each of your 150 verified leads, spend two minutes finding one specific detail. Here is what to look for:

• Recent activity: Have they launched a new product? Opened a new branch? Posted a job listing? Any of these is a trigger event that makes them more likely to need your service.
• Decision-maker name: Do not send your email to "info@company.com." Find the name of the managing director, the operations manager, or whoever would be responsible for the problem you solve. LinkedIn is your friend here, as is the company's own website.
• A specific pain point: Look at their social media or customer reviews. Are people complaining about their delivery times? Are they advertising for staff in a role that suggests they are struggling with a particular function?

Record this in a new column in your spreadsheet. Call it "Personalization Hook." You will use it in Step 5.

Now segment your list. The most useful segmentation for a pilot campaign is by message type, not by industry. Split your 150 leads into three groups of 50. Each group will receive a different outreach message in your pilot. This is how you learn what works before you scale up.

If you are looking for an alternative, budget-focused approach to this entire process, our guide on building a high-converting prospect list without a big budget offers a different angle on the same challenge.

Step 5: Run a Pilot, Measure, and Refine

You now have a verified, enriched, segmented list of 150 prospects. Do not email all of them at once. That is how you burn through goodwill and learn nothing.

Instead, run a pilot. Take one segment of 50 leads and split it into two groups of 25. Send Group A one message. Send Group B a different message. Track the response rate for each. This is a simple A/B test that tells you which message resonates with your ICP.

What should those two messages be? That depends on your product and your audience. But as a starting point, you can use the templates in our guide on cold email outreach templates for African sales teams. The key is to test a different value proposition or a different opening hook, not just a different subject line.

For example, if you sell accounting software to small businesses, you might test:

• Message A: Focuses on saving time and reducing errors in bookkeeping.
• Message B: Focuses on helping the business get ready for tax season and avoiding penalties.

Both are valid value propositions. The pilot tells you which one your specific audience cares about more.

Track these metrics for your pilot:

Metric	What It Tells You	Target for Pilot
Delivery rate	Whether your email infrastructure is healthy	Above 95%
Open rate	Whether your subject line and sender name are trustworthy	Above 40%
Reply rate	Whether your message is relevant to the recipient	Above 10%
Positive reply rate	Whether the prospect is a real fit for your offer	Above 5%

If your reply rate is below 5%, your list is probably fine, but your message is wrong. Go back to Step 4 and look at your personalization hooks. Are you actually referencing the specific detail you found? Or are you sending a generic message with a name swapped in?

If your delivery rate is below 90%, you skipped a verification step. Go back and check your emails.

After the pilot, take the winning message and send it to the remaining 100 leads. You now have a repeatable system: define ICP, search, verify, enrich, test, and scale.

For freelancers who are running this process solo, the Sales Prospecting Playbook for African Freelancers adapts this same framework for a one-person operation.

Why 100 Leads Is Better Than 4,000

There is a temptation to measure your sales effort by the size of your list. A list of 4,000 contacts feels impressive. It feels like you have options. But a list of 4,000 unverified, unsegmented, unenriched contacts is not an asset. It is a liability. It will take you weeks to work through, and the vast majority of it will be dead weight.

A list of 100 verified, enriched, segmented prospects is a different thing entirely. You can work through it in a week. You can personalize every message. You can track every response. You can learn what works and what does not. That learning is more valuable than the list itself.

This is the "less is more" principle applied to sales. It is not about being lazy. It is about being deliberate. Every hour you spend on verification and enrichment is an hour you save on follow-up calls to people who were never going to buy.

As the team at Aqqute notes in their analysis of lead generation strategies for Nigerian businesses, the most effective strategies are not about casting a wider net. They are about understanding your market and targeting your message with precision.

Before you start your next search, ask yourself one question: would I rather have 4,000 numbers that might be wrong, or 100 businesses that I know need what I sell? The answer should be obvious.

Frequently Asked Questions

What is the difference between a lead list and a prospect list?

A lead list is a raw collection of contacts that match broad criteria, such as "businesses in Lagos." A prospect list is a filtered, verified, and enriched subset of that list, where each contact has been confirmed as a likely fit for your specific product or service. You build a prospect list from a lead list by applying your ICP, verifying contact details, and adding personalization notes.

How do I define an ICP for a Nigerian SME context?

Start with the basics: industry, location, and size. Then add Nigerian-specific factors like payment behaviour (do they pay for software or services on retainer?), regulatory exposure (are they subject to NAFDAC, FIRS, or LASG compliance?), and growth stage (are they expanding or contracting?). Talk to your current best customers and ask what they have in common. That commonality is your ICP.

What specific search queries should I use in LeadThur to find niche businesses?

Think like a customer searching for the business, not like a salesperson searching for a category. Instead of "logistics company," search for "freight forwarder Apapa." Instead of "beauty salon," search for "lash extension studio Lekki." The more specific the query, the more niche the results. Run multiple specific searches rather than one broad search.

How do I verify if a phone number or email is still active?

For phone numbers, call. It takes 30 seconds. For emails, use a free email verification tool that checks the domain's mail exchanger (MX) records. You can also send a low-volume test email to a small sample and monitor bounce rates before you send to your full list.

What is the ideal number of leads to start a cold outreach campaign?

Start with 100 to 150 verified leads. This is small enough to manage manually but large enough to give you statistically meaningful response rates for an A/B test. Once you have refined your message based on this pilot, you can scale up to a larger list.

How do I segment my list for A/B testing my outreach messages?

Split your list into two groups of equal size, ensuring each group has a similar mix of industries and company sizes. Send Message A to Group 1 and Message B to Group 2. Keep everything else constant: send at the same time, use the same sender name, and use the same follow-up cadence. Only change the variable you are testing.

What metrics should I track to know if my lead list is good?

Track delivery rate (above 95% is good), open rate (above 40% is good), and reply rate (above 10% is good). If your delivery rate is low, your verification is poor. If your open rate is low, your sender reputation or subject line is weak. If your reply rate is low, your message or your list targeting is off. Each metric isolates a different part of your process.
