Signal-Based Outreach: How to Stop Sending Random Emails and Find the Right Customer at the Right Time

About five years ago, while trying to find new clients for my agency, Mayas.Digital, I found myself stuck in the most classic and inefficient loop in digital marketing: building random lists and sending hopeful cold emails. These efforts were nothing more than a black hole that consumed our time and motivation. I knew then that I had to change something. I realized I needed a story to acquire customers, and more importantly, that story had to intersect with the customer’s story at the right time.

The event that truly defined this mindset shift and gave birth to the strategy we call “Signal-Based Outreach” was our potential engagement with the 68 dealers of one of our major clients across Turkey.

Instead of using the old methods to reach these 68 dealers, we did something completely different this time. We had already been introduced to all of them through a Google Ads project for their parent company, so we had a “warm” list. But we never sent a single email saying “let’s sell you our services too.” Instead, we patiently started listening to them in the digital space.

When we noticed that many of them were not active as companies on LinkedIn, we started following the personal profiles of the founders and managers. We took note, one by one, of who was showing interest in digital marketing by liking relevant articles or commenting on related topics. After a few months of this “passive intelligence” gathering, we had identified 18 dealer-managers who were showing the strongest signals of interest.

That’s when we took action. We reached out to these 18 individuals with personalized messages that offered solution-oriented strategies tailored to their specific interests. The result?

A full 15 of those 18 companies we targeted agreed to work with us. That’s an incredible conversion rate of 83% on the group we focused on. Overall, we successfully converted 22% of the entire potential market of 68 dealers over a period of two to six months.

What was the secret to this success? It wasn’t a big budget or hundreds of phone calls; it was the right strategy and patience. Our only investment was the time it took to prepare a single, smart notification that understood the target audience’s problem and offered them a door to a solution. The return on this small but intelligent investment was 15 new, willing customers.

It was at that moment we understood that the secret to B2B customer acquisition isn’t what we say, but when and how we say it. This was the data-proven power of the strategy we call ‘Signal-Based Outreach.’ Now, I’m going to explain what this strategy is and how you can use it to lock onto your target instead of firing randomly in your own project.

Let’s Clarify the Concepts: The Difference Between Intent Detection and Signal-Based Outreach

As you saw in our story, the secret to our success was timing. To perfect this timing and turn it into a strategy, we need to clarify two fundamental concepts that are often confused but are actually different: Intent Detection and Signal-Based Outreach.

Understanding the difference between these two will transform your marketing efforts from random attempts into surgical operations.

1. What is Intent Detection? – Answering “WHO is Interested?”

Intent Detection is the analytical process of scoring and predicting a potential customer’s buying intent based on their behavior. It’s an analytical task that usually focuses on actions a user takes on platforms you control. It seeks to answer questions like:

Who visited our pricing page more than three times?
Who downloaded our e-book on “How to do SEO”?
Who watched our product demo video to the end?

Its purpose: To provide marketing and sales teams with a prioritized list. It tells you, “Of these 1000 leads, these 50 are ‘hotter’ right now—focus on them first.”

2. What is Signal-Based Outreach? – Answering “WHEN and HOW Should I Reach Out?”

Signal-Based Outreach, on the other hand, is the proactive strategy of taking action at the exact moment a real-time event (a “signal”) from the outside world indicates a need or an opportunity. This is an operational and opportunistic task.

Let’s use a simple analogy:

Intent Detection is the sonar device a fisherman uses to see where schools of fish are under the sea. It tells you where the potential is.
Signal-Based Outreach is seeing the exact moment that school comes to the surface—a splash, a diving bird, a movement in the water—and casting your line at that exact spot, at that exact moment.

Summary Table: Key Differences

Feature	Intent Detection	Signal-Based Outreach
Focus	Analysis & Scoring (“Who?”)	Action & Timing (“When?”)
Timeframe	Generally Past & Current Behavior	Real-time Event (Trigger)
Data Source	Your own data (Analytics, CRM)	Public data (LinkedIn, news, job boards)
Approach	Generally Reactive	Proactive & Opportunistic
Goal	To prioritize an existing list	To initiate a new, timely conversation

The Strongest SaaS Growth Signals (Where to Cast Your Line)

Now that we’ve clarified the concepts, let’s get to the most exciting part: where should we cast our line? Through years of experience, I’ve noticed some key signals that show when a SaaS company is most “open” to new collaborations and organic growth.

Remember, our focus here is on signals that most clearly indicate a need for organic growth and customer acquisition.

1. Business Lifecycle Signals: “Rookie or Veteran?”

In my opinion, the most important signal is understanding where a company is in its journey.

Early-Stage SaaS: A newly founded SaaS is naturally more open to any help and collaboration to survive and get its first customers. For them, it’s a battle for existence.
Growth-Stage SaaS: Companies that have just closed a funding round or are hiring aggressively are loudly declaring, “We have a budget and a clear intention to grow.” This is the perfect time for collaborations with a budget.

2. Marketing & Budget Signals: “We’re Spending Money on Growth”

Where a company spends its money shows its priorities.

Active Ad Campaigns: Seeing a company actively running Google or LinkedIn ads is clear proof that they take marketing seriously and have a budget for growth. This shows they are open to discussing marketing topics.
Paid Backlink Acquisitions: Similarly, detecting that a prospect is acquiring paid placements or backlinks (using tools like Semrush or Ahrefs) signals that they are investing in SEO and authority. This opens a door to offer them more advanced link-building strategies.

3. Website & Product Change Signals: “Something New is Happening”

Changes on a company’s digital storefront are precursors to strategic shifts inside.

Redesigns, New Products, or Pricing Changes: A major website redesign, a new product page, a pricing update, or a new campaign launch are all signs of internal momentum. These signal that the company is preparing for a new move in the market and may need marketing support. It’s possible to catch these signals before anyone else with change monitoring tools, like RobotAlp, a project for which I provide consultancy.

4. Social Signals: “This is on Our Agenda”

Sometimes the strongest signals are in the most public places.

LinkedIn Interactions: When a manager at your target company likes an article on “content marketing” or joins a discussion about “link building,” it’s a valuable signal that the topic is on their mind right now. Using tools like LinkedIn Sales Navigator to monitor these social signals allows you to understand their current priorities and interests deeply, providing the perfect opening for a relevant conversation.

Reading these signals correctly transforms us from just another cold emailer into a strategic partner who shows up at the exact moment the customer has a need.

The Signal Hunter’s Tech Stack

Now that we understand the theory and the signals, let’s talk about the technology and tools that allow us to hunt for these signals and act on them. Remember, there’s usually no single magic tool; the best results come from intelligently using a “stack” of tools that work together.

We can separate these tools according to the two main pillars of our strategy:

1. Intent Detection Tools

These tools help us answer the question “WHO is interested?” and understand the intent behind our prospects’ digital footprints.

Leadfeeder (now part of Dealfront): This tool shows you which companies visit your website, where they came from, and which pages they spend time on. It’s fantastic for understanding the intent of “hidden” visitors who don’t fill out a form.
BuiltWith / Wappalyzer: These tell you which technologies a website is using (e.g., are they on HubSpot, Intercom, or Shopify?). This is an invaluable “technology signal” for personalizing your offer.
Google Alerts & Feedly: These instantly notify you when new content is published online about your target companies, keywords, or industry news. This is perfect for catching news signals like a new funding round or product launch.
6sense or ZoomInfo: These are more advanced, enterprise-level intent data platforms. They tell you which companies are actively researching topics related to your solution, allowing you to find prospects who need you but don’t know you yet.

2. Signal-Based Outreach & Automation Tools

These tools take the signals we’ve captured and help us take action, answering the question “WHEN and HOW should I reach out?”

Clay.com: One of the most popular and powerful tools for “signal hunting” right now. It allows you to combine data from various sources (LinkedIn, websites, news) and automatically trigger a personalized outreach draft when a specific signal occurs (e.g., when someone starts a new job).
Lemlist / Instantly.ai: As we’ve discussed, these platforms are designed for creating personalized email sequences and automatically following up with prospects who don’t reply.
LinkedIn Sales Navigator: The most powerful social signal hunter for B2B. It allows you to closely track the shares, comments, and job changes of your target individuals and companies, giving you the perfect context to start a conversation.
Zapier: This acts as the “glue” that connects different tools. It allows you to build automations like, “When Leadfeeder detects a new company visiting our site (signal), automatically save it to a Google Sheet and send me a Slack notification (action).”

Remember, these tools are only enablers. The real magic comes from combining the data from these tools with our strategy and experience to reach the right person, at the right time, with a genuinely helpful and sincere message.

Conclusion: Stop Firing Randomly, Start Listening for Signals

We’ve reached the end of this in-depth guide. As you can see, customer acquisition in the B2B SaaS world is no longer about sending more emails or shouting louder. Success is about listening smarter, waiting for the right moment, and being prepared when that moment arrives. Years of trial and error, failed projects, and wasted efforts have taught me the most important lesson: instead of randomly knocking on your customer’s door, you must wait for the valuable “signal” that shows they have opened it for you.

If you only take a few things away from this article, let them be these:

Listen First, Then Speak: Build the foundation of your marketing on monitoring the public signals that show what your prospects need (job postings, social media interactions, technology changes). Don’t act until you’ve heard what the market is telling you.
Open the Door with Value: When you catch a signal, your first contact should never be about “selling something.” Build trust by offering a small but valuable piece of help tailored to their problem (a free mini-analysis, a relevant resource). The sale will come as a natural result of that trust.
Build the Right Tech Stack: It’s impossible to track these signals manually. Scale this process by building your own “signal hunting” system with an Intent Detection tool and an Outreach Automation tool.
Be Patient: This is not a get-rich-quick scheme; it’s a strategy that requires patience and discipline. Waiting for the right signal is always more profitable than sending 100 wrong emails.

I hope this guide provides you with a roadmap as you build your own growth strategy. At Shub, we will continue to develop more resources and tools to help you implement exactly these kinds of strategies.
