Email services
Three distinct roles, never overlapping:
- Transactional — sign-in links, receipts, contact-form replies. One sender: Resend.
- Marketing newsletter — general audience announcements, drip campaigns, hand-composed visual emails. EmailOctopus, 2.5K subs free.
- Technical newsletter — Markdown-native, API-driven digest for the developer audience. Buttondown, 100 subs free.
The technical / marketing split is locked in
decisions/architecture/newsletter-split-buttondown-emailoctopus.md.
The Buttondown adapter is wired into
@chirag127/oriz-omnipost per
decisions/architecture/cross-post-engine.md.
