Newsletter Writer

Drafts a weekly digest from your sources. Replaces a $55k Content Marketer.

The Problem

An SMB owner spends $55k/yr on a Content Marketer who pulls links from blogs, Twitter, and Slack, summarizes them, and writes a Friday newsletter that hits open-rate quotas. The role is 80% gather-summarize-format work — exactly what an agent does well.

The Outcome

Friday 6am: agent pulls last 7 days of sources you flagged → drafts a 600-word digest with subject line variants, reading-time estimate, and 3 CTA options. You approve in Slack; it queues to Mailchimp/Substack/ConvertKit.

Day in the Life

Mon-Thu: tags new items in your Drive/Slack/RSS as 'newsletter-worthy' with one-line summaries

Fri 6am: drafts digest from week's flagged items + writes 3 subject-line A/B variants

Fri 9am: posts Slack preview with stats (avg item readtime, click-bait score, subject CTR predictions)
