Write once. Web, inbox, and AI search.
A rich editor that renders a fast web page and a bulletproof email from one source, on your own domain. Server rendered, so search crawlers and AI assistants read it directly.
The editor
One source, both formats
You keep a document. The platform makes it a page and an email.

Renders as you type.
What you see is the post. No CMS to wire up, no template language to learn.
Portable markdown underneath.
Not a proprietary block format. A post pastes in cleanly, and nothing is locked to us.
Saves itself.
Drafts autosave as you type. Close the tab mid sentence; the sentence is there when you come back.
Publish now, or Friday.
Set a publish time and the post goes live without you.
See it as a reader first.
Preview the page before it is public, and send yourself a test issue before subscribers get one.
Write it yourself, or don't.
The same editor and publish path serve what you write by hand and what your agent drafts.
SEO and AI search
Readable by everything that reads
Your publication lives on your own domain, so the SEO equity is yours from the first post. There are no goodsender subdomains.
Fast pages, clean URLs.
Server rendered HTML with no JavaScript shell in the way. Sitemaps, RSS, canonicals, and full meta control.
Open to AI search.
Search crawlers and AI assistants read the page itself: server rendered, on your domain, with a canonical, a sitemap, and a feed.
Your domain, your equity.
Connect your domain, publish under your name, and every ranking signal accrues to you.
✓ server rendered HTML
✓ canonical + og meta
✓ clean URL on your domain
✓ /sitemap.xml
✓ /rss.xml
Subscribe flow
The form is the consent flow
Subscribe forms, popups, and a hosted subscribe page, wired into enforced double opt in. Quiet readers get re confirmed after 120 days; unsubscribes and complaints suppress automatically.
Your list
Bring the list you have
Import your subscribers in bulk. The quiet ones get a re opt in first, so an old list gets re confirmed rather than blasted.
A fast blog and a newsletter that lands.
Publish on your own domain, reach the inbox on the engine made by email people.
No paywalls. No ad network. Just the inbox.
