RSS → Qwen → Beehiiv. A daily niche-industry newsletter on autopilot, sponsorship-monetized at 1K+ subscribers.
Tweet hook
Industry-specific daily newsletters at 5K subs sell sponsorships at $400-1500/issue.
The bottleneck is curation. I built it: RSS in, Qwen-summarized issue out, Beehiiv publishes.
$0 marginal cost per issue (local Qwen).

Subject: daily {niche} newsletter on autopilot
Hi {first} — saw your {Substack / blog / podcast} on {niche}.
Building a niche daily newsletter is half curation, half writing.
I built an engine that automates 80% of both: pulls RSS feeds you
choose, summarizes via local Qwen, drafts the issue, pushes to
Beehiiv.
You still curate the feed list + add 1-2 personal-take paragraphs
weekly. Daily issues ship at $0 marginal cost.

Documentation
newsletter-engine
Programmatic niche newsletter on autopilot. RSS aggregation + Qwen summarization + Beehiiv publishing. Designed for sponsorship-monetized niches at 1K-100K subscribers.
Why it makes money
- Niche industry digests sell sponsorships at $200-$2000 per issue starting at 1K subscribers. (See: Morning Brew Daily, The Hustle, Industry Beat, B2B Bytes.)
- Qwen-powered = $0 marginal token cost. Cloud Claude/GPT for daily news at 1K-10K subs would cost $50-500/month. Qwen local: $0.
- Operator-as-owner — you run it, you sell sponsorships, you keep 100% of revenue. Or sell as a managed-service to a niche expert at $500-2000/mo flat.
