A fully self-hosted newsletter platform — opt-in flow, branded templates, full DKIM/SPF/DMARC alignment — that won't go away when the next SaaS round of pricing changes lands.
Most newsletter SaaS providers price linearly with subscriber count. By the time a list is at 50K subscribers, the monthly bill is several thousand pounds — for a service that is, technically, sending emails.
Self-hosting flips the unit economics. A small VPS handles 100K+ subscribers comfortably; the only marginal cost is the SMTP relay (which is <$0.50 per 1,000 emails on a Resend or Mailgun plan). The break-even vs. SaaS lands at around 5K subscribers.
The newsletter is intentionally architected so that if the underlying platform changes, only the API layer needs to swap — the content database, sender domain, list segmentation, and brand templates all remain portable.
If you have a service business, a vertical SaaS product, or a sector hub that needs scalable, conservative-quality search content with proper lead routing — we run engagements like this regularly.
