Email Newsletter Digest

Use this skill to send a digest of newsletter emails received within the last 1 day.

Read settings.json at the start of every invocation. For settings structure and maintainer notes, see REFERENCE.md.

When To Use

Use this skill when the user wants to:

• send a newsletter digest email
• send the newsletter digest to multiple people
• schedule the digest every morning or on another cadence
• update which labels count as newsletters
• update which senders count as newsletters
• update who receives the digest

Settings

Read settings.json at the start of every invocation.

The settings file contains:

• newsletter_labels_csv
• newsletter_senders_csv
• digest_recipient_emails_csv
• recipient_delivery_mode

Rules:

• newsletter_labels_csv may be null or empty if newsletter_senders_csv is populated
• newsletter_senders_csv may be null or empty if newsletter_labels_csv is populated
• both cannot be null or empty at the same time
• if both are populated, the Gmail search must use OR semantics across both groups
• digest_recipient_emails_csv may contain one or more comma-separated email addresses
• recipient_delivery_mode controls how emails are sent to multiple recipients
• supported values:
  • individual to send one email per recipient
  • group to send one email with all recipients in To
• if recipient_delivery_mode is omitted, default to group

Agent Workflow

1. Immediately send a short acknowledgement such as: "I'm preparing the email newsletter digest now."
2. Read settings.json.
3. Validate that at least one newsletter filter is populated and at least one recipient email is configured.
4. Run the bundled runner at ~/.openclaw/skills/email-newsletter-digest/scripts/newsletter-digest.py in a single blocking command with a generous timeout so you can wait for its stdout result. Do not background it and do not rely on follow-up polling for this skill.
5. Summarize each matching newsletter, build the digest, and send it using the configured recipient_delivery_mode.
6. When the run finishes, send a short completion message naming the recipients and the newsletter count.

If the user asks to update labels, senders, recipients, or recipient delivery mode:

• edit settings.json
• preserve the comma-separated format
• remove duplicates and empty entries

If the user asks to schedule it:

• use OpenClaw's normal scheduling or cron mechanism
• do not ask the user to write shell commands
• if the user says "every morning" and does not specify a time, use a reasonable morning time in the system timezone

Core Rules

• Use gog gmail messages search to fetch individual newsletter emails.
• Use gog gmail thread get --full first for body extraction.
• If the body looks like a placeholder, fall back to gog gmail get --json and extract the best MIME part.
• Use summarize to turn each newsletter into bullet points.
• Unless the user explicitly asks for a different summarizer model, let summarize use its own configured/default model.
• Deduplicate by Gmail message id so each newsletter is summarized once per run.
• Only include matching emails from the last 1 day.
• If no newsletters are found, report that plainly and do not send anything.
• If the run fails or all summaries fail, send a failure email to the configured recipients with the likely cause when possible.
• If only some newsletters fail to summarize, still send the digest and then send a warning email describing the failures.
• Keep user interaction natural-language-first. Do not tell the user to run Python or shell commands themselves.

Query Construction

Construct the Gmail search from the settings file:

• labels only:
  • label:Newsletters newer_than:1d
• senders only:
  • (from:a@example.com OR from:b@example.com) newer_than:1d
• both populated:
  • (label:Newsletters OR label:finance OR from:a@example.com OR from:b@example.com) newer_than:1d

Reporting Back

• Always acknowledge the request before starting work.
• For a successful run, report which recipients were sent the digest and how many newsletters were included.
• For settings changes, summarize exactly what changed.
• For scheduled runs, confirm the cadence in plain language.
• If gog or summarize fails, surface the error instead of hiding it.
• Never fail silently. If the digest cannot be sent, tell the user plainly what went wrong.
