Cold email is harder than it used to be.
Inboxes are flooded. Spam filters are smarter. Prospects ignore anything that smells like a template. Most agencies are still running the same playbooks from 2021 — and wondering why their reply rates keep dropping.
You're sending more, getting less
Volume goes up, replies go down. Your team is burning hours on outreach that never converts.
Generic templates don't work anymore
Buyers can spot a mail merge in two seconds. Without real personalisation backed by real data, you're invisible.
You're paying for activity, not outcomes
Retainers, "managed services", expensive tools — and at the end of the quarter, you still can't point to the revenue it generated.
There’s a better way to do this.
A system built for how cold email actually works in 2026.
Most agencies focus on one thing — usually copy or volume. We built Synthiser around three layers that compound on each other. Each one fixes a different reason your outreach isn’t working.
Infrastructure
We make sure your emails actually reach the inbox.
Spam folders are where 90% of cold emails die. We build out the technical foundation — sending domains, DNS records (SPF, DKIM, DMARC), warm-up cycles, deliverability monitoring — so your emails consistently land where prospects will see them.
- Dedicated sending infrastructure separate from your main domain
- Continuous deliverability monitoring
- Inbox placement testing across major providers
Strategy
We figure out who to target and what to say.
Lists from Apollo and a {{first_name}} field aren't a strategy. We work with you to define your ICP precisely, then build targeting using multiple data sources to find the right accounts at the right moment — companies hiring, growing, raising, or showing other buying signals. Then we write copy that actually sounds like it was meant for them.
- ICP definition workshop
- Multi-source lead list building
- Copy frameworks tested across thousands of sends
Intelligence Layer
We use live campaign data to find what's actually working.
Most agencies "iterate" by guessing. We built a data intelligence layer that analyses every campaign in real time — surfacing which subject lines convert, which audiences respond, which angles close. The campaigns get sharper every week instead of getting stale. No one else in this space is doing this.
- Live performance insights, not vanity metrics
- Continuous campaign optimisation based on real data
- Compounding results month over month

Case Study
Maverick Associates
Before Synthiser
Marcus Nixon’s UK recruitment firm was navigating one of the toughest markets in years. Reduced hiring, tighter budgets, and a saturated outreach landscape meant new business was harder to come by than ever.
After 2 months with Synthiser
A steady flow of high-quality client meetings. New partnerships secured across both the UK and US markets. A healthy pipeline of roles to fill — without Marcus’s team spending a single hour on outbound.
“The recruitment industry has taken a real hit over the past year, but since partnering with Synthiser, our business development has finally started to gain real momentum.”

The messages we wake up to.
A few real Slack messages from clients. Names blurred for privacy.
Real messages from real Synthiser clients. Client identities protected.
Is Synthiser right for you?
This is for you if...
- You're a B2B service business with a clear ICP
- Your average client is worth £/$5K+ in revenue
- You can handle 5–15 new qualified meetings per month
- You want a partner, not a vendor — someone iterating with you, not just sending volume
- You'd rather pay for outcomes than activity
This isn’t for you if...
- You sell to consumers (B2C)
- You're looking for the cheapest option on the market
- You need leads tomorrow — this is a system, not a hack
- You can't take 30 minutes to onboard properly
- You're not ready to actually take more sales calls
How we work together.
Pay only for qualified meetings.
We don’t charge retainers in your first engagement. You pay for meetings that match your ICP and show up. If a meeting doesn’t fit your criteria, you don’t pay for it. Simple.
After we’ve proven results together, some clients move to a hybrid retainer-plus-performance model for predictability. But that’s a conversation we have when you’re ready, not a contract we push at the start.
Common questions.
Setup typically takes 1–2 weeks (infrastructure, list building, copy approval). Most clients see their first meetings booked in weeks 3–4. From there, volume compounds as the intelligence layer learns what's working for your audience.
Three things. First, we don't charge for activity — we charge for outcomes (qualified meetings). Second, our intelligence layer means campaigns get better over time, not stale. Third, we're founder-led — you work directly with someone who understands your business, not an account manager passing tickets.
Complete a detailed onboarding form (about 30 minutes), join a kickoff call, and approve the campaign assets before launch. After that, your only job is taking the meetings we book.
We define this with you during onboarding — typically based on company size, role of the contact, budget signals, and timing. If a meeting doesn't match what we agreed, you don't pay for it. No grey areas.
Yes — but only if you do it properly. Mass-blasted templated emails are dead. Targeted outreach with real personalisation, proper infrastructure, and continuous optimisation works as well as it ever has. That's what we build.
Because we charge per qualified meeting, you only pay for value delivered. If we can't book qualified meetings for your business, you don't pay. We take on the performance risk so you don't have to.
B2B service businesses across most industries — recruitment, agencies, consultancies, professional services, and more. If your average client is worth £/$5K+ and your buyers can be reached over email, we can probably help. Book a call and we'll tell you honestly if we're a fit.
Yes. We build the infrastructure on domains you own, and you keep all the lead data and campaign assets. We don't believe in vendor lock-in.
