How to Book Your First Calls for a New Client (Without Wasting the First 30 Days)
Troy Aitken breaks down the exact first campaign he runs for new clients — and the tool that makes the lead list almost build itself.
The first 30 days with a new client are the ones that matter most. Get results fast and you build trust. Stall out while you "figure things out" and you're already fighting buyer's remorse. So when I bring on a new client at BuzzLead, I'm not experimenting, I'm running a proven first campaign that gets us to booked calls as quickly as possible.
Here's exactly how I approach it.
The Real Problem With Day One
Every new client comes with a learning curve. I need to understand their offer, their market, what makes their best customers tick. That takes time. But the client doesn't care about my learning curve, they care about results.
So the move is to find a shortcut that's also genuinely smart. And the smartest shortcut I've found is to stop guessing who the right prospects are and start cloning the client's best existing customers instead.
Start With What's Already Working: Their Best Customers
Before I touch a single sending account or write a single line of copy, I ask the client one question: who are your best customers right now? I want names, websites, whatever they have. Ideally a couple of strong case studies, too.
Those existing customers are gold. They've already bought. They already see the value. That means companies that look exactly like them are the highest-probability prospects we can possibly go after for a first campaign. This isn't a theory, it's the fastest way I know to reduce risk in the opening weeks of an engagement.
The Tool That Makes This Dead Simple: Ocean
Once I have those customer websites, I plug them into Ocean. If you haven't used it, the concept is straightforward: you give Ocean a handful of URLs, and it goes and finds thousands of companies that look like those businesses, same size, same industry, similar digital footprint, whatever signals it's using under the hood.
The output is a lookalike lead list. Not a broad industry scrape, not an Apollo filter-fest with 50,000 half-relevant contacts. A tight, targeted list of companies that closely resemble the people who already pay your client money.
That specificity matters enormously for a first campaign. When I'm building the opening sequences, I can write messaging that speaks directly to that profile. And because I have the client's actual case studies in hand, real results from real customers, I can fold those outcomes straight into the scripts. The prospect sees their own industry reflected back at them, and they see proof that the client has already delivered for businesses just like theirs.
That combination is hard to argue with.

Why This Setup Wins the First Campaign
There are a few reasons this approach consistently works as a starting point.
First, it cuts research time dramatically. Instead of spending two weeks building personas from scratch, I'm working backward from reality. The client's best customers already tell me everything I need to know about who to target and what they care about.
Second, it gives the copy a backbone. "We helped [similar company] achieve [result]" is one of the most disarming cold email openers you can write. When that claim is true and the prospect can tell the example is relevant to them, response rates reflect it.
Third, it sets up a productive feedback loop. If the lookalike list books calls, I know the ICP is validated and I can scale. If something's off, I know early and I can adjust before we've burned through months of goodwill.
At BuzzLead, we manage 32,000+ sending accounts and have driven over $8 million in client revenue. Across that volume, the pattern holds: first campaigns that start from a validated ICP almost always outperform first campaigns built on broad assumptions. Ocean is just the tool that makes that validated starting point easy to generate quickly.
What to Do With the List Once You Have It
The list from Ocean is a starting point, not a finished product. I'll typically enrich the contacts, pulling decision-maker names, titles, verified emails, and then layer in any additional filters that make sense for the client's offer. But the heavy lifting is already done. I know who I'm going after and why.
From there, it's about writing a tight sequence: a strong opener that references a relevant case study, a clear value prop, and a simple call to action. No gimmicks. No walls of text. The personalization comes from the targeting, not from manually researching every single prospect.
That's how you get to booked calls in the first 30 days instead of spending those 30 days still figuring out who to email.
Key Takeaways
The first 30 days with a new client are critical, moving fast on a smart first campaign kills buyer's remorse before it starts.
Ask for the client's best existing customers and case studies before building any list or writing any copy.
Plug those customer URLs into Ocean to generate a lookalike list of thousands of similar companies automatically.
Lookalike targeting means your messaging is grounded in real, relevant proof from the jump, making it far easier to write copy that lands.
A tight, ICP-matched list with case study-driven scripts is the most reliable formula for booking calls in a first cold email campaign.
Frequently Asked Questions
What is Ocean and how does it work for cold email? Ocean is a lookalike company tool. You input the websites of a few ideal customers, and it returns thousands of companies with a similar profile. For cold email, this means you can build a highly targeted lead list in a fraction of the time it would take to manually define and filter an ICP from scratch.
Why is the first 30 days so important when onboarding a new client? Early results build trust and justify the client's decision to hire you. Without quick wins, buyer's remorse sets in fast. A focused first campaign targeted at proven lookalike prospects gives you the best shot at booking calls before that window closes.
How do case studies fit into the first campaign's messaging? If you're targeting companies that resemble a client's best customers, you can reference what you achieved for those customers directly in your outreach. That makes your proof immediately relevant to the prospect and significantly strengthens the email's credibility.
Do I need a huge list to make this work? No. A smaller, laser-targeted list built from real lookalike data will almost always outperform a bloated, loosely filtered list. Quality of targeting matters more than raw volume, especially in the first campaign where you're still learning what resonates.
