52.9% open rate from cold emails to ESA, CERN, and european defence primes.
Client: Beamide srl
Sector: Radiation simulation SaaS for nuclear, space, and defence
What we built: Outbound infrastructure (sending domains, sequences, reply detection, CRM handoff)
Headline result: 52.9% open rate · 88.9% conversation-to-deal conversion
Cold email to enterprise procurement is supposed to be a numbers game. Send 10,000, get 30 replies, hope two convert. Beamide didn't have that volume to play with. Their total addressable market is in the hundreds, not the millions. So we threw out the volume playbook and built something different.
The situation
Beamide builds simulation software used by physicists at ESA, CERN, and european defence primes. It's the kind of product that takes 6 to 18 months to sell into a single account. The buyers are senior research engineers and procurement officers at organisations where security clearance gates the inbox.
The total addressable market is roughly [CONFIRM: number] qualifying organisations across europe. There is no SDR-and-volume play here. Every email goes to someone whose time is measured in hundreds of euros per hour and who ignores anything that smells of marketing.
Before we got involved, outbound was:
The pain was simple. Not enough conversations with the right people, and the conversations that did happen weren't moving forward.
What we built
Sending infrastructure that doesn't get filtered.
Three new sending domains, [CONFIRM: number] inboxes per domain, full SPF / DKIM / DMARC alignment, and a 2.5-week warm-up before any real send. The technical floor matters more in technical industries. CERN's spam filter is not casual.
A sequence written for engineers, not for procurement.
The first email reads as one specialist contacting another about a specific simulation problem. Not "I'd love to schedule a quick chat about your needs." The email actually demonstrates we understand what they do. That's the only reason a CERN engineer opens a second email from us.
Reply detection and handoff to a real human.
Every interested reply pings Beamide's team within minutes. The system does not auto-reply, does not auto-book, does not pretend to be the founder. The handoff is fast and explicit. A senior buyer can tell the difference between a tool and a person within two messages.
Tight ICP segmentation.
We did not blast a single sequence at every engineer in europe.
CRM reflection of every conversation.
Every reply, every meeting, every dropped thread is logged into [CONFIRM: which CRM] so the Beamide team can see the pipeline as it builds.
The result
52.9%
Open rate
On cold emails to senior engineers and procurement officers at named european research and defence organisations. Industry benchmark for B2B cold email is 30 to 40%.
88.9%
Conversation-to-deal conversion
Of the prospects who entered a real two-way conversation, [CONFIRM: number] became closed deals. This number reflects deal closure on conversations that progressed past the first reply, not blanket reply rates.
[CONFIRM: number]
Qualified meetings booked
Over [CONFIRM: timeframe — first 90 days? first 6 months?] with named buyers at procurement-ready organisations.
The 88.9% number deserves a real explanation. It is not a blanket conversion rate. It measures conversations that reached the second meaningful exchange and then progressed to a closed contract. The reason it's that high is the same reason the volume is low. Every conversation that started was with someone we had pre-qualified down to the named role at the named organisation. We were not optimising for replies. We were optimising for replies that mattered.
