How to Run a Cold Email Campaign Targeting Seed & Series A Software Startups That Raised Yesterday (2026)

Quick Answer — To run a cold email campaign targeting software startups that raised Seed or Series A in the last 24 hours, use Origami. It doesn’t just find the leads; it has a built-in email sequencer so you can launch the whole campaign from one place. Right after you’ve built a hyper-fresh list of founders and hiring managers (using the method from our list-building guide), you refine, create a 3‑touch email sequence, and hit send — all without exporting a single CSV.

This guide assumes you already have a list in Origami. If you haven’t built it yet, stop and read how to build a list of Software Startups That Raised Seed or Series A in the Last 24 Hours first. Then come back here to run the campaign.

Step 1 — Refine and segment your list before the first send

A list of every startup that raised yesterday is still a raw list. You need to qualify who’s actually worth emailing and split them into segments that make your follow-ups feel personal.

What “qualified” looks like for yesterday’s fundraise

• Founder or hiring manager reachable — If Origami returned a generic info@ or news@, drop that contact. You want decision-makers (CTO, VP Engineering, Head of Sales) who can actually buy or hire.
• Company size that fits your solution — A 5‑person Seed startup has different needs than a 40‑person Series A. If your tool is built for teams of 20+, filter by employee count.
• Relevant tech stack signals — Origami’s enrichment often shows tools they use. If you’re an AWS partner, prioritize startups already on AWS. If you sell to remote‑first teams, look for Slack + Notion.
• Geography / time zone — Seed founders in Berlin likely won’t reply to an email sent at 2am their time. Group by location so you can set send times later.

How to do it in Origami: After your list is built, use the inline filters. You can sort by company size, role, location, and keywords. Remove any contact that doesn’t have a direct email. Create separate saved lists like “Seed – CTOs – US” or “Series A – VP Sales – EU” so your email sequences can be laser‑targeted.

I typically end up with 3‑5 tight segments from a raw list of 300 contacts. That’s where the response rates live.

Step 2 — Create the email sequence (exact copy you can steal)

You’ve got a list of warm‑but‑cold prospects who just got funded. The window to reach them is narrow — the first 24‑72 hours after a raise is when they’re overwhelmed with congratulatory noise but also actively planning spending. Your email must cut through.

Origami gives you two ways to build the sequence:

1. Paste your own templates — Write your 3‑touch sequence directly into the sequencer, set delays between touches (e.g., Day 1, Day 3, Day 7), and launch. You have full control over copy.
2. Let the agent write it — Ask Origami’s AI agent to generate a personalized 3‑day email sequence for all leads automatically. The agent uses each prospect’s title, company, and industry to tailor the messages. If you’re scaling fast, this is a huge time-saver.

Below, I’ll share the manual templates I use for software startups that just raised. They work — you can customize them with your own value prop.

The 3‑touch sequence (Seed & Series A startups)

These are designed to feel like a peer reaching out, not a sales pitch. The first email congratulates them and ties their new reality to a specific problem. The follow‑up adds a different angle. The breakup is direct and leaves the door open.

---

Day 1 – Initial cold email (send within 24 hours of raise news)

Subject line: ’s raise — timing for ? Preview text: Quick thought from the outside

Body:

Hey ,

Saw you closed the — congrats. I’m sure your inbox is chaos right now.

One thing I’ve seen at this stage: the pressure to hire senior engineers spikes overnight. Most Seed founders don’t realize how long it takes to onboard the first 3–5 core hires.

We help startups like cut that time from 6 weeks to under 10 days. Worth a look?

---

Day 3 – Follow‑up (different angle, no “just checking in”)

Subject line: One hire many Seed teams forget Preview text: The person who keeps the wheels on

Body:

,

Almost everyone focuses on engineers after a raise. But the ops person who wrangles vendors, payroll, and compliance? That’s the hire that burns founders out first.

Our platform lets you spin up a dedicated ops process without hiring a full‑time person — it’s why teams at adopted us the week after their Series A.

Open to a 20‑min call to see if it fits?

---

Day 7 – Final breakup (short, no guilt)

Subject line: Closing the loop — Preview text: Last message from me

Body:

,

Haven’t heard back, so I’ll leave you alone after this.

If you ever want to see how we’re helping post‑raise teams move faster on , my calendar is open: .

Best,

Why this sequence works for this audience:

• First email acknowledges the raise immediately (they’re still riding the high).
• It names a real, immediate problem—hiring acceleration—not “increase efficiency.”
• Follow‑up pivots to a less obvious pain point (ops burnout), showing you understand the startup journey.
• Breakup is polite and doesn’t burn bridges; some founders reply at this stage because they were just too busy earlier.

When using the agent, you can give a prompt like: “Generate a 3‑email sequence for software startups that raised Seed/Series A in the last 24 hours. Tone: peer, direct. Focus: first email congratulates and ties to a specific post‑raise hiring pain. Second email highlights an overlooked operational bottleneck. Third is a friendly breakup with a calendar link.”

The agent will personalize each message with the recipient’s actual company name, role, and even mention their tech stack if that data is in Origami.

Step 3 — Send the sequence directly from Origami (no exports, no external tools)

This is where most outreach workflows fall apart. You build a list, export a CSV, upload to some ESP, mess up the merge fields, and spend an hour troubleshooting. Origami removes that entirely.

With the built‑in email sequencer, you launch the whole multi‑step campaign right from the same platform where you built and refined the list.

How it works

1. Set delays — Choose the cadence between emails. For this audience, I use Day 1, Day 3, Day 7. You can adjust per segment.
2. Launch — Hit “Send now” or schedule for a specific time (e.g., start sending at 9am their time). No need to sync with an external tool.
3. Tracking in the same dashboard — Opens, clicks, replies all show up next to each contact. You don’t switch windows.
4. Prospect context stays visible — When you notice a founder opened 3 times but didn’t reply, you can immediately see their enriched profile: company size, role, tools they use. You remember why you reached out, making a manual follow‑up much smarter.
5. Automatic un‑enrollment — If a lead replies (even “not interested”), Origami pulls them out of the sequence. No more accidentally sending a breakup email to someone who just booked a meeting. That one feature alone saves your reputation.

What sending is included

The sequencer itself is part of all paid plans (starting at $29/month). You only pay for the credits you used to enrich the leads — the sending is free. So after you’ve identified and enriched your list, you can run the full email campaign at no extra cost.

Expected results

With a list of genuinely fresh, well‑qualified contacts, here’s what I usually see for software startups that raised in the last 24 hours:

• Open rates: 40–60% (the raise news means they’re checking email more, and subject lines referencing the raise get attention)
• Reply rates: 5–10% on the whole sequence (many replies come on Day 3 or Day 7 after the initial email warmed them up)
• Meeting booked: 2–4% of total contacts — a 2% rate on 200 leads is 4 high‑intent conversations with post‑raise buyers.

If reply rates are below 3%, don’t change the list first. Iterate on the messaging. Try a different pain point in email 1, shorten the follow‑up, or tweak the breakup timing. Only after testing 2‑3 copy variations on the same list should you go back and re‑qualify the list.

The takeaway

You can find, qualify, and email software startups that raised yesterday entirely inside Origami. No hopping between tools. No broken merge tags. Just a clean, repeatable process that gets you into conversations when founders are actually thinking about spending their new capital.

Start with the list‑building guide, then come here, refine, copy the sequence, and launch. It works.
