Hey, it's Christian from the RevGrowth newsletter.
I'm emailing you a 3-minute playbook that you can implement today to
start building targeted, qualified, and verified lead lists for your
outbound campaigns.
Today I'm covering the exact 4-step process we use at RevGrowth to
develop lead lists — from a raw idea to a sending-ready
contact list.
WHY MOST LEAD LISTS UNDERPERFORM
Most people build lead lists like this: open Apollo, throw in a few
filters, export 5,000 contacts, upload to their sequencer.
Then wonder why they're sitting at a 0.4% reply rate.
The problem isn't Apollo. The problem is they skipped the two most
important steps that happen BEFORE you ever touch a database.
Here's the full process — the one that produces 90%+ qualified lists
instead of the typical 50-60%.
STEP 1: MAP YOUR TAM
Before you open any database, you need to understand who you're
actually trying to reach.
Most companies think they know their TAM. They don't. They know their
top 3 industries. They've never thought about the other 12.
What we do: feed your offer into GPT o3 and have it generate every
possible industry you can service. You'll usually find 5-10 verticals
you've never considered targeting.
Then define your base requirements — employee size, revenue range,
geography. This is NOT your ICP yet. This is just everyone who can
technically use your product.
TAM ≠ ICP. Don't mix them up.
STEP 2: DEFINE YOUR ICP SEGMENTS
Now that you know who CAN buy, figure out who SHOULD buy.
Best way to do this: pull up your CRM. Analyze your current clients.
Go through closed calls. Ask — why did these people buy? What do they
have in common?
You want to outline:
Best-fit personas — what job titles are actually making the buying decision?
Team structure signals — do they have 10+ salespeople? A dedicated sales team?
Tech stack — are they running HubSpot, Salesforce, Klaviyo?
Buying signals — recently funded? Actively hiring SDRs? Expanding into new markets?
Best-fit industries — where have you gotten results fastest?
Once you have this, combine your personas with your industries to
create segments. A sales leader at a construction company is a
completely different ICP segment than a sales leader at a SaaS
company — even if the job title looks identical.
ALWAYS build lists one segment at a time. Mixing segments destroys
your messaging and tanks your reply rates.
STEP 3: SOURCE YOUR COMPANIES
Now you can actually start pulling data. Three methods we use
depending on the situation:
Online directories + Google Maps
Best for local businesses, niche industries, and industry association
members — anyone Apollo doesn't have good coverage on. Use Instant
Data Scraper or an Apify scraper to pull these. You can build some
incredibly powerful lists this way for verticals that are hard to
find anywhere else.Dedicated account databases
Tools like Crunchbase, BuiltWith, Store Leads, and Shovels are built
for specific industries or use cases. Data quality is significantly
better than Apollo — more frequently updated, more complete. More
expensive, but worth it when targeting precision matters.Apollo
Cheapest, fastest, best for high-volume campaigns. Apollo's gotten
a lot better over the years. Don't sleep on it for bulk sends.
One tip that makes a big difference on Apollo: don't rely on their
built-in seniority and function filters. They pull a ton of roles
that won't actually fit your persona. Instead, take your target job
title, feed it into Claude, and have it generate keyword variations
for that specific role. Plug those into Apollo's keyword search.
Your list accuracy goes up dramatically. Takes five minutes.
STEP 4: QUALIFY FIRST, ENRICH SECOND
This step is what most people skip — and it's costing them a
fortune in enrichment credits.
Once you have your company list, import it into Clay. Before you
touch contact enrichment, you qualify the companies first.
Simple reason: you don't want to pay to find emails for 10,000
contacts at companies that don't fit your ICP. Qualify first, enrich
the ones that pass.
Here's how the qualification flow works in Clay.com:
Run a Claygent to pull company summaries and confirm industry fit
Use Apify, Clay agents, or Serper to pull any specific data points you need — pricing pages, hiring signals, tech installs, filings, etc etc
Use LeadMagic to fix missing or incorrect data (employee count off, wrong industry, no company description)
Filter out unqualified companies — but keep borderline fits, they're still worth contacting in many cases
Once your companies are qualified, run contacts through your
enrichment waterfall:
Prospeo.io → LeadMagic.io → backup finder
Verify your emails. Done.
Now you have a targeted, ICP-qualified, verified list ready to
import into EmailBison and start sending.
The whole thing looks more complicated than it is. Once you build
the Clay workflow once, it runs on repeat for every list you build
going forward.

Clay qualification table, enrichment waterfall, the whole thing —
