The problem
Email tools optimise for sending more, faster — which is exactly how an unreviewed AI draft ends up in 4,000 inboxes with the wrong price in it. Speed without a gate is a liability.

Newsletter
AI drafts the email. A human sends it.
A block-based newsletter editor where AI can draft the whole email — and sending is deliberately impossible without a human.
The actual Newsletter module — same theme, same layout as the app. Example data.
The problem and how sSystm solves it
How sSystm does it
The Newsletter module has a block editor — headings, paragraphs, buttons, images, dividers, spacers — and a hard rule: there is no send tool over MCP. Your AI drafts complete newsletters as ordered blocks; the draft lands in the module where a human reviews, picks the audience and sends.
What Newsletter gives you
Built deep, so the module actually carries the weight of real client work.
01
Block editor
Compose from structured blocks — heading, paragraph, button, image, divider, spacer — instead of fighting an HTML template.
02
No send tool. On purpose.
sstm_newsletter_draft creates drafts; nothing over MCP can send. The gap between draft and sent is where your judgement lives.
03
Voice-grounded drafts
AI drafts read your Tone of Voice profiles first — personality, dos and don'ts, banned words — so the draft sounds like you before you even touch it.
04
Campaign-linked
Newsletters attach to campaigns, so every send is accounted for in the plan it serves.
Newsletter on the MCP surface

1sstm://newslettersYour AI, via MCP
Your AI reads past newsletters over sstm://newsletters and drafts new ones as structured blocks with sstm_newsletter_draft. It can write every word — and still cannot send. That is the point.
