Start from your best customers, not from a tool
A B2B prospect list is not a random pile of companies. It is a selection of businesses that look like the customers you already serve well. Write down what they have in common first: industry, size, region and the problem you solve for them.
With that profile in hand, you rarely need to invent a list. The companies are already grouped in public places. Your job is to collect, clean and segment them, and Riftjaw lets you import any list and split it into segments from one dashboard.
The steps from profile to prospect list
Work through the steps in order; skipping the cleaning step is what makes most lists fail.
| Step | What you do | Done when |
|---|---|---|
| 1. Define the profile | Describe the companies that buy from you: niche, region, size, signals | You can say in one sentence who is on the list |
| 2. Pick the sources | Choose where these companies are listed: maps, directories, registers | Each source matches the profile |
| 3. Collect | Pull the companies into one list with name, website and location | Every row has at least a website or address |
| 4. Clean and dedupe | Merge rows with the same domain, drop closed or off-profile companies | No company appears twice |
| 5. Enrich | Add category, region and a business contact route per company | You can sort and filter every row |
| 6. Segment | Split the list into groups that each get their own message | Every segment has a reason to be written to |
Where prospect lists come from
Map results
Local businesses with address, category and website. Strong for local services; dedupe chains by domain.
Directories and registers
Pre-sorted by niche or officially registered. Check that the website still exists before you keep a row.
Association member lists
Companies that invest in their trade. Small in volume, often high in fit.
Your own customer base
Look-alikes of customers you already serve. The smallest source and usually the best one.
Habits of good list builders
- Build one focused list per campaign instead of one giant list for everything.
- Set a minimum: a company without a website or category does not enter the list.
- Keep a source column so you learn later which sources produce customers.
- Note the collection date and refresh lists that are a few months old.
- Read ten random rows by hand before you write; that sample predicts the rest.
Frequently asked questions
How big should a B2B prospect list be?
Big enough to learn from and small enough to keep quality. A few hundred well-chosen companies in one segment teaches you more than thousands of random rows.
What should a prospect list contain per company?
At minimum the company name, website, location and category, plus a business contact route. Add the source and collection date so you can judge freshness later.
How do I find email addresses for my prospect list?
Start from the company website: many businesses publish a general or role address. Riftjaw can also derive likely addresses from the domain, which you verify before the first send.
How often should I update a prospect list?
Before every new campaign, do a quick pass: remove closed companies, check websites and add new businesses from the same sources.
Do I need credits?
No. There are no credits and no data tax: enrichment runs automatically without a per-row meter.
