A newsletter platform with no open or click tracking, for writers who would rather not surveil the people reading them.

What Hyvor Post leaves out defines it. There is no click or open tracking anywhere in the platform, which takes the tracking pixel and the rewritten link out of every message a subscriber receives. The result is a newsletter tool built for readers rather than funnels.
It is based on Hyvor Relay, the same authors' self-hosted email API, with a Symfony backend in PHP, a SvelteKit frontend for the console, embed and archive, and PostgreSQL underneath. Issues are composed in a clean rich text editor with markdown support.
The console covers what running a list actually requires.
- Multiple newsletters: one account manages several newsletters with scoped access per tenant.
- List management: subscribers are imported and maintained without reaching for a separate tool.
- Templates: email templates are customizable rather than fixed.
- Signup form: an embeddable form drops onto an existing website.
- Archive site: every issue is published to a generated archive website automatically.
- Console API: newsletter management can be automated from your own code.
One caveat matters more than any feature. The project is open source under AGPL-3.0 but not yet ready for self-hosting, with OpenID Connect setup and hosting documentation still outstanding. Until those land the hosted service is the practical way to use it, and pull requests on the missing pieces are welcome.
