OpenClaw Email Automation: Fable-Driven Inbox Zero with Agent & Cron Jobs

A Reddit user in the excavation and business acquisition space shared a detailed setup for automating their email workflow with OpenClaw. They run a Google Workspace with two work email addresses, receiving a high volume of emails that require responses, delegation, and spam filtering. Previously, a VA in the Philippines handled this but lacked full business context, causing more work in explaining tasks than doing them. With OpenClaw, they built an automated system that handles most of it.

Setup

• Separate agent with full company/personal context and memory, reading each email address.
• Strict rule set originally written for the VA as a baseline.
• Inbox zero system with folders:
  1. Personal review – for the ~5% needing unique personal action.
  2. Action – for emails OpenClaw thinks should be addressed but has no rule for.
  3. Waiting – for sent emails awaiting response.

Cron Jobs

Hourly cron: Filters SPAM, applies forwarding/response rules, moves others to Action folder, notifies user. Uses Fable on high for insights and spot-on responses. It messages with full context from other emails, goals, and company knowledge, suggesting next steps and drafts. It can even run a full LBO analysis on a CIM (Confidential Information Memorandum) without prompting. User can approve next steps via cron output or let items stay in Action.

Daily morning cron: Checks Personal Review, Action, and Waiting folders, flagging items needing attention. User often responds via Slack channel directly to the agent with instructions for detailed handling.

Costs and Value

Pushing limits on Claude 5X plan; upgrade to 20x costs $100/month more, which user deems worth it. Reports massive time savings after only a few days.

This is a practical example of using OpenClaw for email automation, combining cron jobs, Fable, and context-driven agents. For developers, it shows how to set up similar workflows with folders, rules, and LBO analysis—though that last part is niche. The key takeaway: define clear rules, use multiple folders for triage, and let the agent handle routine tasks while keeping human oversight.
