AI Agents overview

Letterhead AI agents assist you with newsletter work by automating content checks, drafting emails, and analyzing performance. Each agent runs on-demand or on a schedule and surfaces “judgments”—suggestions you can accept or dismiss.

Core agents

Letterhead includes three core agents:

1. Email Content Check — A pre-send validation agent that flags issues like broken links, missing alt text, and other content problems before you send.
2. Assemble — Drafts a newsletter from items in your Curations library, matching your channel’s voice.
3. Analyze — Reviews your content and performance data to surface insights and recommendations.

Access agents

1. Navigate to Agents (company-level dashboard).
2. View all available agents and their status.
3. Select an agent to run it on-demand or manage its schedule.

How agents work

Agents surface their output as “judgments”—suggestions and findings. After running an agent:

1. Review the judgments in the activity feed or agent results panel.
2. Accept judgments you agree with (to apply recommendations).
3. Dismiss judgments you don’t need.
