Multi-Channel Outbound: 23 Replies From Tiny List!
If you’re not leveraging multi-channel outbound in 2025, then you’re definitely leaving a ton of money on the table. I mean it. While your competitors are still stuck sending basic cold emails, the smart operators are combining email, LinkedIn, and other channels to create campaigns that actually get responses.
Let me share a case study with you that’s going to blow your mind. We generated 23 positive replies from a tiny list size in just 8 days. Yeah, you read that right. Not a massive database of 10,000 contacts. A tiny list. And we’re going to break down exactly how we did it.
Why Multi-Channel Outbound Works
Here’s the thing: your prospects aren’t just sitting in their inbox waiting for your email. They’re on LinkedIn. They’re checking multiple platforms throughout the day. When you hit them across multiple channels with a coordinated message, you’re not being annoying—you’re being visible. And visibility is what converts.
The key is orchestration. You’re not just blasting the same message everywhere. You’re creating a sequence that feels natural, that provides value, and that meets your prospect where they already are.
The Tools You Need
For this campaign, we used a powerful combination of tools that work together seamlessly:
- SmartLead – For cold email campaigns with superior deliverability
- HeyReach – For LinkedIn automation that doesn’t get you banned
- Clay – For data enrichment and building targeted lists
- Make – For connecting everything together with automation
Each of these tools plays a specific role in the ecosystem. You could try to do this manually, but honestly, you’d waste weeks of time and probably mess up the coordination between channels.
How We Set Up The Campaign
Let’s get into the nitty-gritty. Here’s the step-by-step process we followed:
Step 1: List Building with Clay
First, we used Clay to build our target list. The beauty of Clay is that it doesn’t just give you basic contact info. You can enrich your data with multiple sources, verify emails, find LinkedIn profiles, and even pull in company information that helps you personalize your outreach.
We kept our list small and hyper-targeted. Quality over quantity, always. When you’re doing multi-channel outbound, you want to make sure every prospect is genuinely a good fit. Otherwise, you’re wasting touches across multiple platforms.
Step 2: Setting Up Email Sequences in SmartLead
Next, we built our email sequences in SmartLead. This platform is phenomenal for deliverability. You can connect multiple email accounts, warm them up automatically, and rotate sends to maintain your sender reputation.
Our email sequence was simple: a strong opening email focused on a specific pain point, followed by two follow-ups that provided value rather than just asking for a meeting. No one likes a pushy salesperson, and your emails shouldn’t sound like one either.
Step 3: LinkedIn Outreach with HeyReach
While the emails were going out, we coordinated LinkedIn touches using HeyReach. This is where the magic happens. We sent connection requests with personalized notes, and for those who accepted, we followed up with messages that complemented (not duplicated) our email content.
The timing here is crucial. You don’t want to hit someone on LinkedIn the same day they get your first email. We typically space it out by 2-3 days to create multiple touchpoints without overwhelming the prospect.
Step 4: Automation with Make
To tie everything together, we used Make to create automation workflows. This ensured that when someone replied to an email, they were automatically removed from the LinkedIn sequence. Or if someone engaged on LinkedIn, we could adjust the email cadence accordingly.
This level of coordination is what separates amateur outbound from professional campaigns. You’re treating your prospects like humans, not just entries in a database.
The Results: 23 Positive Replies
In just 8 days, we generated 23 positive replies. These weren’t “not interested” or “take me off your list” responses. These were genuine conversations with people who wanted to learn more.
From a small list. In just over a week.
The conversion rate was significantly higher than single-channel campaigns we’ve run in the past. Why? Because we were present across multiple touchpoints, providing value, and meeting prospects where they were most active.
Key Takeaways
If you’re going to implement multi-channel outbound, remember these critical points:
Personalization matters. Don’t just blast generic messages. Use the data you have to make each touch feel relevant and specific.
Timing is everything. Space out your touches across channels. You want to be persistent, not annoying.
Value first, ask second. Every message should provide something useful. Lead with insights, not requests.
Track and optimize. Monitor which channels are getting the most engagement and adjust accordingly.
