Email newsletters
Who it's for
Substack authors, indie creators, and B2B newsletter editors.
Common challenges
Old issues are hard to find; recurring structure is repetitive; subject lines steal time.
How WriteX helps
Archive as issues/001.md with a fixed section template. The agent proposes subject lines and preview blurbs; attach past issues for consistent voice.
Typical workflow
- Drop raw material in
inbox/. - Three-part outline for this week.
- Agent drafts body + subject candidates.
- Finalize and paste into your ESP.
- Move to
issues/with open-rate notes.
Practical tips
Keep a file of high-performing subject patterns; draft long-form in WriteX, not the ESP.
