Goal: Make all aspects of cold outbound functional, transparent, and accessible

• infra/domain setup
• list creation
• enrichment
• research
• intent signals
• ai personalization
• sequencing

To run locally:

• download pnpm
• download docker and cli
• copy the example.env into .env with cp .env.example .env
• pnpm i
• pnpm dev
• navigate to localhost:3000

CI

Every pull request and every push to main runs .github/workflows/ci.yml, which fails the build if any of the following fail:

• pnpm install --frozen-lockfile
• pnpm exec tsc --noEmit (typecheck — there is no typecheck script yet)
• pnpm lint
• pnpm test:int

test:int boots Payload, so CI provisions a Postgres 16 service container and sets DATABASE_URL_PAYLOAD + PAYLOAD_SECRET for the run. To reproduce the CI job locally, mirror the env from the workflow and docker compose up -d db before running the same commands.

MVP features:

✅ - enter a domain and see SPF / dkim / dmarc records _{Want this without spinning up coldflow? Use the standalone CLI: npx dmarc-doctor yourdomain.com — same checker, zero deps, prints colored verdicts plus 'how to fix'.}

• connect google smtp accounts _{Mail landing in spam from a self-hosted relay? Diagnose the transport layer in 30s with npx smtp-warmer test --host smtp.example.com --port 587 --user me@example.com — TLS handshake, AUTH+RCPT sandbox (no mail sent), DNSBL reputation, reverse-DNS alignment. Zero deps, zero API keys, composite 0–10 score.}
• upload a csv of contacts
• Create a single-step email sequence with basic personalization ({first_name}).
• Send the emails (with a strict, safe sending limit).
• See a basic dashboard showing "sent" and "replied."
• Silent-reply follow-up: when a prospect replies asking for pricing/details (or any question) and then goes silent, automatically schedule a short follow-up 3 days later. The follow-up cancels itself if the prospect replies again before it sends. See Pending follow-ups on the dashboard.

Move the needle TO-DO list:

• Templates for popular email needs i.e "onboarding for SaaS" — see /templates
• Integration with GHL / N8N

Content TO-DO list:

• "How to Achieve Perfect Cold Email Deliverability with a Self-Hosted Tool"

• "The Complete Guide to Building a Custom Lead Scoring Model with Coldflow"

• "Why Your Shared IP is Killing Your Campaigns (And How to Take Back Control)"

• Listicles - Top 10 lists. I actually tested different platforms, used real screenshots and update them frequently.

• Guest posts - Find tech-related/ B2B / SaaS websites and pitch them content. Make sure there's context. For ex. one of my posts is on a Woocommerce site, so my article is how X can help grow your ecommerce store.

• Existing listicles - If you search for "Best X", there are dozens of articles already ranking in Google. Reach out to them and ask to be featured. Some will ignore you, some will ask you to pay, but eventually - some will say yes. I've ended up on 10+ existing sites.

• Original research - Launch a Startup report get it picked up by some big media outlets. I try to link to the research 2-3 times in either my own content or in guest articles.

• I use a variation of the anchor "According to research by X Tool". This is the strongest way to build authority.

• Keep content fresh. Never more than 6 months old. Each month, I updated content that is close to being more 6 months+ and rewrite the intro and include 1-2 internal links to new content.

Ideas:

The real trouble starts only after the prospect replies. this is the part that every tool completely ignores. and this is the part that matters the most.

When someone has already replied... they’re warm. they’ve shown interest. they asked a question. they said yes send details. they requested pricing. whatever it is. and then sometimes they go silent for 3 or 4 days. sometimes even 7. this is where the follow up actually decides the deal. these are the follow ups that convert. not the cold ones.
