Funding-round opener — 4 variants.

Four templates for the four funding-event shapes: Seed/Series A (small round, sharp angle), Series B+ (saturated field, must cut through), debt facility (uncrowded, technical), and M&A / acquisition (stack rebuild). Each variant has a fill-in template, the worked example we sent, and reply-rate context from the campaign. Designed to work alongside the funding-round playbook.

Variant 01

Seed / Series A — sharp angle

Smaller rounds at smaller companies. The inbox isn't as saturated (~ 115–200 emails/week vs 300+ at Series B), so the variant can be more conversational and the angle can be a single sharp observation rather than a multi-layered one.

When to send
Day 3–7 post-announcement. Earlier than B+ because the inbox isn't as full. Friday afternoon still outperforms Tuesday morning.
A
Seed / Series A variant
~ 62 words · 4 paragraphs
Reply rate 9.4%
Tips: the subject is intentionally a specific question, not a celebration. Anything with "congrats" or the dollar amount in the subject drops opens by ~40% in our seed/A data. The "2–3 other teams" line is the trust signal — keep the number small to stay credible.
Result: 11 of 117 replies (9.4%), 4 booked demos, 2 closed-won across 6 months ($28k and $44k ARR). Campaign ran March–April 2026 against Series A engineering leaders post-round.
Variant 02

Series B+ — cut through saturation

The hardest funding-round inbox to land in. ~300 cold emails in week 1 at Series B, ~420 at Series C+. The template has to do more work in line 1 because the buyer is filtering hard. Every word has to earn its place. Saturation-aware design: subject names a specific decision, not the round.

When to send
Day 9–18 post-announcement. Skip Tuesday–Wednesday entirely — the round-week inbox peaks then. Friday afternoon or the following Monday is the quieter window.
B
Series B+ variant
~ 75 words · 4 paragraphs
Reply rate 7.8%
Tips: the subject must do double duty — name the use-of-funds quote AND the operational consequence. This passes the receipts test before the body opens. Don't use the dollar amount or "congrats" anywhere. The Friday-afternoon send is non-negotiable for this variant.
Result: 9 of 116 replies (7.8%) — meaningful given Series B inbox saturation. 3 booked discoveries, 1 closed-won at $86k ARR in Q3 2026. Campaign ran April 2026 across Series B CROs at recently-funded US SaaS.
Variant 03

Debt facility — uncrowded, technical

The highest-yield funding-round variant we ship. Debt facilities generate ~ 28 cold emails/week (vs 300 at Series B), so the field is uncrowded enough that the template can be more technical and specific. The buyer's CFO actually reads these.

When to send
Day 5–14 post-announcement. Debt facilities tend to land on the CFO's desk for covenant-management work inside 30 days of close — get the conversation started before that project staffs up. Tuesday or Thursday mornings are fine here; the inbox isn't saturated.
D
Debt facility variant
~ 78 words · 4 paragraphs
Reply rate 13.2%
Tips: this variant can be more technical than the others — debt-facility recipients are CFOs and finance ops, and the technical specificity reads as credibility, not jargon. Don't soften the language. Use the named covenant or instrument when you have it.
Result: 13 of 98 replies (13.2%), 6 booked CFO calls, 2 closed-won at $36k and $52k ARR. Campaign ran April 2026 against CFOs at growth-stage companies that closed venture debt facilities in the prior 30 days.
Variant 04

M&A — stack rebuild

Acquisitions create two distinct buying windows: the acquirer is rebuilding the stack for the combined entity (60–120 day window), and the acquired company is renegotiating every vendor contract (immediate). The variant below targets the acquirer side — the bigger ARR opportunity. For the acquired-company side, anchor the email on the renewal-conversation timing instead.

When to send
Day 14–35 post-announcement. The 2-week delay lets the integration-planning conversations actually start internally. Sending in the first week reads as opportunistic and gets ignored.
M
M&A / acquisition variant
~ 70 words · 4 paragraphs · acquirer-side
Reply rate 8.6%
Tips: the acquirer is making real decisions about the combined stack for the first time. Frame the email around the decision shape, not your product. The 60–90-day window is the load-bearing claim — only use it if you've actually seen it hold in your industry.
Result: 7 of 81 replies (8.6%), 3 booked CTO calls, 1 closed-won at $124k ARR (the largest single deal from the funding-round template family in 2026). Campaign ran April 2026 against CTOs at companies that closed acquisitions of engineering-heavy teams in Q1 2026.
05

How to use these.

A few notes on running the templates well — based on what works across the four variants and what we've seen fail in customer campaigns.

Pick the variant by stage, not by personal preference. The B+ variant doesn't work for seed companies (over-engineered), and the seed variant doesn't work for B+ (under-engineered for the inbox saturation). Match the variant to the recipient's round shape.

Don't reuse the same use-of-funds quote across multiple accounts. The whole point of the receipts test is that line 1 is specific to this company. If your template makes it easy to swap one company's quote for another, you've defeated the framework. Use Mama (or whatever research tool) to pull the actual quote per account.

Skip 60–70% of the funding announcements you see. The discipline of skipping is what separates the operators who get 13% reply rates from the ones who get 2%. See the playbook for when not to use this signal at all.

Use the artifact offer (line 4) as the real selling tool. The 1-page doc you offer is doing real work — it's the demonstration that you have something specific to say, packaged in a low-commitment format. If you don't actually have a useful 1-page doc to send when they reply, build one before you send the campaign.

If you'd run these templates

The template is the easy part. Getting the use-of-funds quote per account is the hard part.

Mama's funding signal pulls the use-of-funds quotes, named hires, named geographies, and named investor leads — so when you sit down to fill the {{use_of_funds_quote}} slot, the right detail is already there per account.
