Real-World Automation: Email Digest
The goal
Build a workflow that runs every morning, pulls yesterday's new leads/emails/entries from a source, uses AI to summarize them into a digest, and emails you the result — replacing 20 minutes of manual review.
Building the pipeline
Schedule Trigger (daily 8am) → data source node (Airtable, Google Sheets, Gmail search) → OpenAI/Claude node to summarize into a digest → Gmail/Slack node to deliver it.
Making it robust
Handle the empty-data case (no new entries yesterday — skip the summary and send "Nothing new today"). Add error alerting from Lesson 6 so a silent failure doesn't go unnoticed.
Key Takeaways
- A daily digest combines a schedule trigger, a data source, AI summarization, and delivery.
- Handle the empty-data edge case explicitly.
- Layer in error alerting so silent failures are caught.
- This pattern generalizes to almost any recurring reporting task.
Build your own daily digest
Build a complete daily digest workflow using a real data source you have access to (Gmail, Airtable, a spreadsheet), with AI summarization and email delivery.
