Show HN: Hyvor Post (privacy-first newsletters) & Relay (self-hosted email API)

Hello HN,

We (HYVOR) are excited to launch two new products today:

Hyvor Post (https://post.hyvor.com): a simple, privacy-first newsletter platform with zero tracking.

Hyvor Relay (https://github.com/hyvor/relay): a self-hosted email delivery service. An alternative to services like AWS SES or Mailgun.

We've been working on these two projects for almost a year, and we are super excited to finally release them.

Our release announcement has more insights: https://hyvor.com/blog/hyvor-post-relay. In short, we first added newsletter features to Hyvor Talk (our commenting system), and it proved to make things complicated. So, we started working on Hyvor Post as a standalone newsletter platform. Then, we could not find an SMTP provider that does not include tracking features and has reasonable pricing - so we built our own: Hyvor Relay.

Both products are open-source under AGPLv3. Hyvor Post is cloud-only at the moment. Hyvor Relay is self-hosted only. Compared to traditional solutions like Postfix, Hyvor Relay makes it very hard to make mistakes when sending emails by having built-in health checks for DKIM, SPF, PTR, a DNS server to automate records, etc. Building Hyvor Relay was a significant undertaking for our small team, and we are very happy that we now have a reasonably stable version. We are also working to release a public cloud version in 2026 to help developers reduce email sending costs significantly.

Our team is around on HN - feel free to ask any questions!
