How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
11 rules. 0 are common, 10 are distinctive, and 1 is very specific to this project.
0
Common
Most of the 27 edited versions we read keep these.
10
Distinctive
This author's own choices. Worth a look.
1

“Common” is measured: kept by at least 6 in 10 of the 27 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Cold Outreach
Cold outreach succeeds on technical deliverability and acute relevance, not brute volume. Spray-and-pray sequences destroy domain reputation and land in spam folders. Modern outbound requires isolated secondary domain infrastructure, strict SPF/DKIM/DMARC authentication, automated warmup ramps, and tight multi-channel cadences across Email and LinkedIn.
1. Domain Infrastructure & Deliverability Protocol
Protect your primary company domain by building dedicated outbound infrastructure:
A. Secondary Domain Architecture
- Never send cold outreach from your primary apex domain (e.g.
company.com). If an outreach campaign gets flagged, primary corporate email deliverability is compromised. - Purchase 2–3 lookalike secondary domains (e.g.
trycompany.com,usecompany.com,companyhq.com) configured with Google Workspace or Microsoft 365 mailboxes. - Set up 301 redirects from secondary domain roots to your primary website homepage.
B. DNS Authentication Records (Mandatory)
Before sending a single email, configure four DNS records on every sending domain:
- SPF (Sender Policy Framework):
v=spf1 include:_spf.google.com ~all - DKIM (DomainKeys Identified Mail): Generate a 2048-bit cryptographic key in Google Workspace / M365 admin and publish the TXT record at
google._domainkey.domain.com. - DMARC (Domain-based Message Authentication):
v=DMARC1; p=quarantine; rua=mailto:dmarc-reports@trycompany.com; pct=100; sp=quarantine - Custom Tracking Domain (CNAME): When using tracking pixels or click tracking, use a dedicated subdomain (
track.trycompany.com) with an SSL cert. Best practice: Disable open/click tracking entirely for cold emails to improve inbox placement.
C. Automated Domain Warmup Schedule
Warm up mailboxes for 14–21 days using automated peer networks (Smartlead, Instantly) before sending cold campaigns:
- Week 1 (Days 1–7): 5–10 automated warmup emails/day. Zero cold prospect emails.
- Week 2 (Days 8–14): 15–20 warmup emails/day. Start cold outbound at 5 emails/day/mailbox.
- Week 3+ (Production): 25–35 cold emails/day + 15 warmup emails/day per mailbox.
- Hard Ceiling: Maximum 40 cold emails per mailbox per day. To send 200 emails/day, use 5 mailboxes distributed across 2 domains.
2. Multi-Channel Cadence Architecture (Email + LinkedIn)
Structure outreach across 4–5 touches over a 16-day window:
Day 1: [Email 1] Personal observation + problem statement + low-friction ask
Day 2: [LinkedIn] Profile view + connection request (blank note or 1-line observation)
Day 5: [Email 2] Quick bump with 1-sentence customer proof or metric
Day 8: [LinkedIn DM] Short value drop if connection accepted (no calendar link)
Day 12: [Email 3] Frictionless resource or perspective shift
Day 16: [Email 4] Polite breakup closing the loopHigh-Converting Email Frameworks
- Subject Lines: 2–4 words, lowercase, non-promotional:
quick question,[Company] <> [Prospect Company],re: [Specific Trigger]. - Word Count: Strictly between 50 and 90 words. Long emails trigger cognitive fatigue on mobile screens.
- The Low-Friction Call to Action (CTA):
- Weak: "Can we schedule a 30-minute demo on Tuesday at 2pm? Here's my Calendly link."
- Strong: "Open to checking out the 2-minute breakdown?" or "Worth exploring, or is this not on your radar for Q3?"
LinkedIn DM Rules
- Keep messages under 250 characters.
- Anchor to a public signal: comment on their recent post, hiring announcement, or podcast appearance.
- Never pitch or drop a scheduling link in the connection request note.
3. List Hygiene & Bounce Prevention
- Run every prospect email through real-time verification tools (NeverBounce, ZeroBounce) before loading into cadences.
- Maintain a bounce rate strictly
< 2.0%. Bounces above 3% trigger spam filtering across Google and Microsoft networks.
Critical Rules
- Never send cold outreach from the primary domain used for corporate operations.
- Every prospect email list must be validated immediately prior to sending; never send to stale or unverified lists.
- Keep cold emails under 90 words with a single, clear question rather than multiple demands.
Verification Checklist
- Secondary domains configured with valid SPF, DKIM, and DMARC records.
- Mailboxes warmed up for a minimum of 14 days with >50% warmup engagement.
- Prospect list verified with <2% predicted bounce rate.
- Email copy contains zero spam trigger phrases ("free", "guarantee", "act now", "urgent").
- CTA is conversational and asks for interest rather than booking calendar time directly.
Anti-Patterns
- NEVER exceed 40 cold emails per mailbox per day; distribute volume across multiple inboxes.
- NEVER include calendar links (Calendly/HubSpot) in initial outreach emails; links degrade deliverability.
- NEVER send generic template blasts that lack custom, role-specific personalization triggers.
