Email and newsletters decision
Woodpecker
A competent developer can build a useful subset (sending, campaigns, reply handling, basic deliverability) in ~1 week and maintain it cheaply, but reproducing Woodpecker's lead database, warm-up network, and hosted LinkedIn/multichannel features is impractical without substantial additional investment.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Send personalized cold-email campaigns, schedule follow-ups, receive and classify replies, and track deliverability metrics.
What it still won’t have
- Proprietary Lead Finder (1B+ database) and built-in enrichment credits
- Hosted warm-up network and preconfigured warm-up interactions
- Managed deliverability infrastructure and domain purchasing with SPF/DKIM preconfigured
- Cloud LinkedIn automation / hosted multichannel actions (vendor-managed)
What remains hard
- Product polish and ongoing maintenance

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a self-hosted cold-email outreach service using Node.js (Nest or Express), Postgres, Redis, and a background worker (BullMQ). Implement: 1) SMTP sending worker supporting multiple accounts and adaptive rate limits; 2) campaign builder with templated messages and up to 16-step follow-ups; 3) CSV lead import with duplicate detection and snippet merge; 4) IMAP webhook/connector to parse inbound replies and stop follow-ups (reply detection); 5) integration to an email verification API and a basic deliverability dashboard (bounces, opens, clicks). Out of scope: LinkedIn automation, a 1B lead database, and paid lead-finder credits. Include error handling, retries, unit tests for core modules, and Docker deployment scripts for a single-VM cloud host.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
