Quick Answer: Origami has a built‑in email sequencer, so once you’ve used it to generate a list of radiation shielding companies hiring engineers, you can launch a targeted multi‑step campaign directly—no exporting, no syncing. Here’s exactly how to refine your list, create a sequence that resonates, and send it to start conversations.

If you haven’t built that list yet, read our companion guide first: how to build a list of Radiation Shielding Companies Hiring Engineers. That walkthrough shows you the exact Origami prompt and how the AI agent returns verified names, emails, phone numbers, and company details. This post picks up where that one ends—you have the list. Now let’s turn it into meetings.

Step 1: Build the List in Origami (Refresh)

Even if you already ran this, here’s the prompt you’d type into Origami—and what happens next.

The prompt:
Find radiation shielding companies in the US and Canada that are currently hiring engineers. Include roles like radiation shielding engineer, health physicist, nuclear engineer, or radiation safety officer. Return the hiring manager’s contact details plus company info.

Origami’s AI agent goes live: it crawls job boards, company career pages, LinkedIn, and industry databases, then chains data sources to enrich every match. In seconds you get a table with:

Full name and verified email
Job title (often the hiring manager or department lead)
Company name, size, industry tags (nuclear, medical, defense)
LinkedIn profile URL
Tech/tools they use (MCNP, Attila, Fluka—yes, Origami scrapes tools if publicly mentioned)

You can run that prompt on the free plan—1,000 enrichment credits, no credit card. That’s enough for a tight, 50‑100 lead list in this niche. When you’re ready to scale, paid plans start at $29/month. But the real magic is that you don’t stop at the list.

Step 2: Refine and Qualify the List

A raw export isn’t a campaign. Radiation shielding is a narrow field, but the companies and roles vary wildly. If you blast everyone, you’ll burn through leads and hurt your domain reputation. Spend 15 minutes here.

Remove Bad Fits Immediately

Consultants vs. Builders: Delete firms that only offer radiation survey or dosimetry consulting—they typically don’t hire shielding design engineers. Keep companies that design, fabricate, or install shielding (lead sheet, concrete, tungsten, borated polyethylene).
Research‑only labs: Universities and national labs that study radiation physics but don’t build shielding products? Remove them unless your service is pure R&D staffing.
Duplicate domains: If you have three engineers at the same company, keep the most senior hiring contact and flag the others for later nurturing (you don’t want three emails landing in the same small office on the same day).

Segment by Observable Attributes

Within Origami, use tags to split your list into groups. For radiation shielding, I use:

Sector tag: Nuclear Power, Medical Imaging, Defense & Aerospace, Industrial Radiography
Company size tag: 1‑50, 51‑200, 201‑500, 500+ (a staffing firm cares about headcount; a software vendor might just need any size with an active project)
Role tag: Hiring Manager, Senior Engineer, VP Engineering, CTO—so you can tailor the offer to decision‑maker vs. influencer

What “Qualified” Looks Like for This Audience

A qualified lead is someone whose job is to fill radiation shielding engineering roles now (or in the next 90 days). That means:

Their title includes “Director of Engineering”, “VP Operations”, “Principal Engineer”, “Radiation Safety Officer”, or “Hiring Manager” at a company with active job postings.
The company’s website or LinkedIn shows recent shielding projects: nuclear plant upgrades, LINAC vaults, isotope production facilities, spent fuel storage, etc.
The contact is in North America if that’s your market; if not, adjust the prompt to the regions you serve.

When I run this campaign, I end up with 50‑80 highly qualified accounts. That’s enough to test messaging and get meetings—without overwhelming the niche.

Step 3: Create the Email Sequence

This is where most people freeze. You’ve got a clean list, but you don’t know what to say to a radiation shielding manager. I’ll fix that. First, the two ways to build a sequence inside Origami.

Option 1: Paste Your Own Templates

If you already have a winning sequence, paste your templates directly into Origami’s email sequencer. Set the delay between each touch (Day 1, Day 3, Day 7 is a safe cadence for this audience—they’re not checking email hourly), hit “Launch”, and Origami sends everything automatically. You can insert personalization tokens like [[First Name]], [[Company]], or any custom field from the enriched profile.

Option 2: Let the Agent Write It

Alternatively, ask Origami’s AI agent: “Generate a personalized 3‑day email sequence for my radiation shielding hiring leads. Keep it professional, under 100 words per email, and reference their industry.” The agent pulls each lead’s title, company, used tools, and sector to write messages that feel one‑to‑one. You can still review and tweak the copy before sending.

But if you want to grab a proven, copy‑and‑paste sequence that I’ve used successfully in this exact niche, here it is.

3‑Touch Sequence for Radiation Shielding Companies Hiring Engineers

Touch 1: Day 1 – Initial Cold Email

Subject: NRC updates and your shielding team
Preview: Noticed you’re hiring engineers…

Hi [[First Name]],
I saw [[Company]] has active openings for radiation shielding engineers—no surprise given the latest NRC guidelines and the push for dose optimization. Finding folks who actually know shielding thickness calculations, MCNP modeling, and material selection is brutal right now.

We specialize in placing exactly those engineers. Last quarter we helped a firm like yours fill two shielding roles in 14 days.

Worth a quick call Thursday or Friday?

Best,
[[Your Name]]

Why this works: It references a real regulatory pressure (NRC), names specific skills they’re hunting (MCNP, shielding calcs), and attaches a concrete timeframe (“14 days”) to build credibility.

Touch 2: Day 3 – Follow‑up (Different Angle)

Subject: One thing I forgot about shielding talent
Preview: It’s getting harder…

Hi [[First Name]],
Quick follow‑up—I mentioned the NRC, but there’s another layer: the nuclear new‑build wave (AP1000s, SMRs) is pulling shielding engineers away from medical and defense projects. That means the pool you’re fishing in is smaller than LinkedIn suggests.

We’ve built a network of 400+ pre‑vetted radiation shielding pros, many open to new roles but not actively applying. No fee unless you hire.

Would a 10‑minute call to compare notes make sense?

Cheers,
[[Your Name]]

Why it works: It introduces a macro trend (competition from new nuclear) that creates urgency, offers a specific asset (“400+ network”), and removes risk with “no fee unless you hire”.

Touch 3: Day 7 – Final Breakup

Subject: Closing the loop on [[Company]] shielding hires
Preview: No worries if not…

Hi [[First Name]],
I won’t keep chasing. If finding a shielding engineer who can hit the ground running on ALARA design, concrete/lead attenuation, and regulatory submittals is still a headache, you know where to find me.

Otherwise, happy to stay connected on LinkedIn. And if you ever need a second opinion on a shielding spec, I’ll shoot you an honest answer—no strings.

Best,
[[Your Name]]

Why it works: No desperate close. It re‑anchors the specific pain (ALARA, attenuation, reg submittals), offers a low‑commitment connection, and leaves the door open for future dialogue.

Instantly usable: Copy these into a text file, replace [[First Name]], [[Company]], and your signature, and you’ve got a campaign that speaks the language of a radiation shielding engineering manager.

Step 4: Send the Sequence Directly from Origami

Here’s the part that separates Origami from a list‑and‑CSV workflow.

One Platform, No Exports

You launch the sequence straight from the same dashboard where you built the list. No exporting to a separate ESP, no syncing through Zapier, no CSV upload. Origami’s built‑in email sequencer handles the entire multi‑touch dance. You set the delays—say, 2 days between Touch 1 and Touch 2, and 4 days before the final breakup—and it sends each message automatically.

Tracking Inside the Prospect’s Profile

Once the campaign is running, you see opens, clicks, and replies right next to the lead’s enriched data. So when you get a reply, you’re not wracking your brain: you can see that this contact is a VP Engineering at a nuclear services company that uses MCNP, and that’s exactly why you reached out. Rich profile context lives side‑by‑side with activity.

Automatic Un‑enrollment on Reply

Critically, if someone replies—even with “Not interested”—Origami stops the sequence for that lead. No one gets a breakup email after they’ve already said yes to a meeting. It’s built‑in, no manual intervention.

Pricing Note

The sequencer itself is free on all paid plans. You’re only paying for the enrichment credits used to find and verify the leads. No extra sender credits, no per‑email fee. If you’re on the free plan, the full sequencer is there too—you just won’t have enough credits to scale past 1,000 enrichments, but for a test campaign it’s perfect.

Response Rates to Expect

In this niche, with a well‑qualified list of 60‑80 contacts:

Open rate: 45‑55%. Radiation shielding professionals work in technical environments where email is central. A relevant subject line (see the examples) cuts through.
Reply rate: 6‑12%, sometimes higher if the hiring need is acute. Expect a handful of “tell me more” or “who do you have?” replies.
Meeting rate: 2‑4% from cold outreach is solid. That’s 1‑3 meetings per campaign, which in staffing or high‑ticket material sales can be huge.

When to Iterate on Messaging vs. the List

Low opens: Your subject lines are getting lost. Test referencing a specific regulation (“10 CFR 20 compliance”) or a tool (“Experience with MCNP?”). But if opens stay below 30%, your list may contain outdated email addresses—re‑qualify with Origami’s re‑enrichment option.
High opens, low replies: The body isn’t hitting the pain point. Try a shorter message that explicitly names a daily frustration: “Writing a shielding analysis report under a tight deadline?” Or switch the CTA from “call” to “reply with a time” to lower friction.
Wrong replies or negative feedback: Your qualification was off. Go back to Step 2 and tighten the sector/role filters. Radiation shielding companies that only design shielding analysis software—not installation—may not be hiring engineers, so remove them.
