For cybersecurity startups, cold email can feel like shouting into the void.
Your message may be thoughtful, your ICP may be accurate, and your offer may be compelling, but when your target inbox belongs to a CISO who gets 400 vendor emails a week, “doing everything right” still isn’t enough.
That’s exactly where Steryon found themselves.
With seed funding secured and a clear go-to-market plan in place, the team had everything they needed except results. Replies stopped. Meetings dried up. Confidence started to falter.
That’s when they partnered with LeadSpot.
This blog unpacks how we helped Steryon reboot their outbound strategy, personalize at scale, and build a repeatable campaign engine that delivered 7 qualified cybersecurity opportunities and $650,000 in new pipeline in just 90 days.

From Solid Foundations to Radio Silence: Steryon’s Pain Point
Steryon is a European-based cybersecurity startup tackling a crowded market with a sophisticated solution. Their internal team had already built:
-
Personalized email cadences
-
Sharp messaging
-
Clear ICP documentation
-
Educational content
But performance was falling off a cliff. Despite clean data and confident messaging, replies dried up. Their outbound motion stalled.
The team was asking:
-
Are we sending at the wrong time?
-
Is our message off?
-
Or is the cybersecurity space just too saturated to break into?
And that’s where LeadSpot entered the picture with a completely different approach.
Cutting Through the Chaos: How We Got Steryon’s Attention
Steryon’s first experience with LeadSpot wasn’t just an outreach email; it was a case study in personalization.
We sent:
-
A cold email featuring Steryon by name, referencing their messaging gaps and valuable content pieces
-
A custom landing page with a video reviewing Steryon’s own website and GTM
-
A personalized follow-up video breaking down exactly how we could help them reboot their strategy
We even used AI-based send time optimization based on company behavior and intent signals, so emails hit the inbox at just the right time.
This was a tailored, strategic interruption…and it worked.
Diagnosing the Real Problems in Steryon’s Outbound Engine
Upon onboarding, we took a close look at Steryon’s existing system. What we found wasn’t failure but rather a misalignment.
Here’s what we uncovered:
1. Email Deliverability Issues
Their DKIM configuration was broken, which hurt inbox placement. Most messages weren’t even getting seen.
2. Overly Broad ICP
They had a strong understanding of their buyer, but their lists weren’t behaviorally segmented. This meant the same message was being sent to researchers and budget holders alike.
3. “What” Messaging Instead of “Why”
The copy focused on features and capabilities, not on the unique risk factors or business consequences their buyers cared about.
4. No Behavioral Triggers or Intent Signals
Send timing was random. No engagement signals were being used to prioritize who received what, or when.
None of this is unusual. In fact, most early-stage cybersecurity teams are in the same boat. They’re doing a lot of things right, but in a highly contested market, small missteps can kill performance.
Building a Personalization Engine That Scales
We had three weeks to rebuild Steryon’s outbound approach and we used every minute.
Here’s what we delivered:
Refined ICP and Behavioral Segmentation
We rebuilt their ICP map around buyer behavior, tech engagement, and job function. We created multiple micro-campaigns targeting CISOs, DevSecOps leads, and Heads of Risk separately, with messaging tailored to each.
DKIM and Deliverability Fixes
We reconfigured their entire email authentication setup, including DKIM and SPF records, ensuring inbox placement instead of spam box doom.
Messaging Rewrite
We replaced feature-forward messaging with emotional, outcome-driven copy. We zeroed in on consequences of inaction, category-specific risks, and budget-aligned pains.
Handcrafted Personalized Videos
We created prospect-level videos using each recipient’s own website, referencing their industry, use cases, and potential vulnerabilities. Each video linked to a custom microsite with:
-
A tailored CTA
-
An explainer on how Steryon could help
- Examples of their top customers
- FAQs
-
Smart follow-up routing
AI-Based Send Time Optimization
Using real-time enrichment and behavioral data, we deployed sends when target accounts were most likely to engage.
The Campaign Results: Qualified Pipeline in 90 Days
The outcomes were fast and impressive.
Performance Metrics:
-
11% average reply rate across all segments
-
68% positive reply rate in best-performing campaigns
-
40%+ increase in open rates thanks to personalized videos
-
26% video-to-meeting conversion rate, meaning 1 in 4 prospects who watched a video booked a call
Pipeline Impact:
-
7 qualified cybersecurity opportunities booked
-
$650,000 in forecasted pipeline
-
0 long-term contract required (Steryon started with a flexible, 3-month engagement)
This wasn’t just a spike in activity. It was the creation of a repeatable, scalable outbound motion with consistent, predictable outcomes.
Why It Worked: The LeadSpot Approach
1. It Wasn’t “Cold” Outreach
The best cold emails don’t feel cold. We made every message feel handcrafted. Real video, real targeting, real storytelling. That’s how we broke through CISO inbox fatigue.
2. We Fixed the Technical Foundation
You can’t win if your emails aren’t getting delivered. Fixing DKIM alone gave Steryon back a fighting chance.
3. We Activated Their ICP
We didn’t just define ideal customers, we engaged them based on behavior, timing, and vertical. That’s the difference between a database and a pipeline engine.
4. We Used Creative Personalization Without Burning Time
By combining smart AI data layering with low-friction video tools, we scaled high-quality personalization across hundreds of accounts, without slowing down.
From Fatigue to Focus: What Steryon Has Now
After 90 days, Steryon walked away with more than booked meetings. They now have:
-
A repeatable outbound playbook they can relaunch anytime
-
Validation on which ICP segments respond and convert
-
Messaging that actually resonates with real buyers
-
A playbook to train internal SDRs or scale with partners
-
Conversations with budget holders and decision makers
They didn’t have to flood LinkedIn with ads, hire five more SDRs, or throw money at overhyped intent platforms.
They needed strategy, execution, and timing.
That’s what LeadSpot delivered.
Final Takeaway: In Highly Competitive Markets, Precision Wins
Cybersecurity might be one of the most saturated B2B categories on Earth. That doesn’t mean cold email is dead, it just means your cold email can’t be generic.
If you’re a cybersecurity or B2B tech brand that’s hit a plateau, you don’t need more activity; you need a system that respects the buyer, the inbox, and your brand.
Steryon trusted us to rebuild their outbound with:
-
Creative strategy
-
Clean infrastructure
-
Behavior-based targeting
-
Personalized messaging at scale
It worked.
And it’s replicable.
FAQs: LeadSpot’s Cold Email + Personalization Engine for Cybersecurity Brands
Q1: Why wasn’t Steryon’s original outbound working if their targeting and messaging were solid?
A: In cybersecurity, “solid” isn’t enough. Their campaigns lacked behavioral segmentation, had technical deliverability issues (broken DKIM), and didn’t use intent or timing data. Plus, their messaging focused too much on features, not the risks, emotions, or consequences that drive action.
Q2: What’s different about LeadSpot’s outbound compared to traditional SDRs or cold email agencies?
A: We blend AI-powered enrichment, manual personalization, video-first messaging, and real-time behavior signals. Every touchpoint is designed to feel handcrafted, convert faster, and build credibility, especially in high-noise markets like cybersecurity.
Q3: Do I need to have a mature GTM motion or SDR team to work with LeadSpot?
A: Not at all. Many of our clients are early-stage startups (like Steryon) looking to test messaging, validate their ICP, or create qualified pipeline before hiring internally. We can either run point or supplement your existing team.
Q4: What kind of results can we expect in 30 to 90 days?
A: While results vary by industry and ICP quality, most clients see a noticeable lift in reply rates, engagement, and booked meetings within the first 2–3 weeks. Steryon saw 7 qualified opportunities and $650,000 in pipeline in 90 days.
Q5: Can LeadSpot fix our cold email deliverability problems?
A: Yes. We audit and resolve issues like broken SPF/DKIM/DMARC, domain warming, inbox rotation, and send-time optimization. It’s a key part of every engagement.
Q6: What does a typical engagement look like?
A: Many clients start with a 1 or 3-month test campaign. We overhaul messaging, clean up technical infrastructure, segment your ICP by behavior, and launch personalized, trackable outbound powered by AI and a human touch.
