Email and newsletters decision
EmailOctopus
A competent developer can build a narrow self-hosted campaign-sending workflow and basic analytics in ~1 week, but matching EmailOctopus’s deliverability, integrations catalogue, templates polish and support would be costly to reproduce.
Visit website↗Open-source builds that already do this
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
- Create and send email campaigns to subscriber lists, schedule sends, and track opens/clicks.
What it still won’t have
- Deliverability optimizations and IP warmup expertise
- Polished drag-and-drop editor and prebuilt template library
- Broad catalogue of 1,000+ third-party integrations
- Award-winning customer support and SLA
- Long-term analytics and deliverability reporting depth
What remains hard
- Integration maintenance

Paying is—cheaper in year one.
On cash alone, building overtakes the subscription at 2 seats.

Runnable build prompt
Build a minimal self-hosted email marketing MVP using Postgres, Node.js (Express) backend, React frontend, Redis for job queueing, and Amazon SES for sending. In scope: subscriber CSV import and REST API, simple segment/tag storage, a basic block-based HTML editor with template save/load, scheduling and queued sends via SES, open/click tracking pixels and stored events, campaign scheduling UI, and a reports page for opens/clicks. Out of scope: multi-user teams billing, advanced deliverability tooling, 3rd-party integrations catalogue beyond a Zapier webhook example. Include input validation, background job retries, error handling, and unit+integration tests; provide Docker compose for local dev and a production deployment guide using ECS or a managed VM plus SES credentials.

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.
