Astonish Email Limited
A competent developer can build and operate a functional one-account replacement in about a week; you trade away vendor deliverability, support, and polish but not core sending capabilities.

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. All Astonish Email Limited alternatives, with the arithmetic →
What a replacement has to do
- Send marketing/newsletter campaigns by importing/storing subscribers, designing a template, scheduling a send that uses an SMTP/Email provider API, and report opens/clicks.
What it still won’t have
- Vendor-managed deliverability tuning and ISP relationships
- Built-in templates, analytics polish, and vendor support
- Volume discounts and integrated billing/ UX
- SLA, invoice/enterprise billing flows
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 small newsletter/marketing sender using Node.js (Express) + Postgres + React. Include: subscriber management with CSV import and segmentation; a template editor integrating react-email-editor for composing and saving templates; a campaign scheduler UI that enqueues sends; a sender worker that delivers via AWS SES (or SendGrid) with retries and logs; open/click tracking endpoints that update analytics in Postgres and a simple dashboard showing sends, opens, clicks and bounces. Out of scope: enterprise invoicing, multi-tenant billing, advanced deliverability services and ISP relationships. Include sensible error handling, unit/integration tests for critical flows, Dockerfiles and a deploy script for a single small VPS.
