Use this skill to: Read emails that have been approved by the human Send emails via draft submission (requires human approval before sending) ### Setup First, authenticate with your API key (get this from PostWall dashboard): postwall auth pw_your_api_key_here ### Check for New Emails Returns count of unread approved emails. Ideal for polling. postwall check # Returns: 5 postwall check --json # Returns: {"count": 5} ### List Approved Emails Shows all unread approved emails. postwall inbox # Human-readable list postwall inbox --json # JSON format postwall inbox --limit 10 # Limit results ### Read Specific Email Reads an email by ID. This marks the email as read - it won't appear in future inbox/check calls. postwall read # Shows email content postwall read --json # JSON format ### Mark Emails as Read (Without Fetching) Marks one or more emails as read without fetching their content. Useful for batch processing or when you only need to process email metadata from inbox. postwall mark-read # Mark single email as read postwall mark-read # Mark multiple emails as read postwall mark-read --json # JSON format Use cases: Mark emails as processed after using inbox --json to get metadata Batch mark emails you've already handled Skip emails you don't need to read in full JSON output: { "success": true, "marked": 3, "failed": 0, "results": [ {"id": "abc123", "success": true}, {"id": "def456", "success": true}, {"id": "ghi789", "success": true} ] } ### Send Email (Submit Draft) Submits an email draft for human approval. The email is NOT sent until approved in the dashboard. postwall draft --to "recipient@example.com" --subject "Hello" --body "Email content here" postwall draft --to "user@example.com" --subject "Report" --body "..." --json Returns an approval URL that you can share with the user for quick approval: Draft submitted successfully! Draft ID: abc123-uuid Status: pending Approval URL: https://www.postwallapp.com/dashboard/drafts/abc123-uuid Share this URL with the user to approve the email. JSON output includes approveUrl: { "success": true, "draft": { "id": "abc123-uuid", "status": "pending", "created_at": "2024-02-12T10:30:00Z", "approveUrl": "https://www.postwallapp.com/dashboard/drafts/abc123-uuid" }, "message": "Draft submitted for approval" } ### Update Draft Update an existing pending draft. Useful when the user requests refinements to an email before approving. postwall update --subject "New subject" postwall update --body "Updated email content" postwall update --to "new-recipient@example.com" --subject "New subject" --body "New content" postwall update --subject "Refined subject" --json Note: Only pending drafts can be updated. Once a draft is sent or rejected, it cannot be modified. JSON output: { "success": true, "draft": { "id": "abc123-uuid", "to": "recipient@example.com", "subject": "Refined subject", "body": "Updated content", "status": "pending", "createdAt": "2024-02-12T10:30:00Z", "updatedAt": "2024-02-12T11:00:00Z" }, "message": "Draft updated successfully" } ### Check Draft Status Check if a draft has been approved, rejected, or sent. postwall status # Shows status postwall status --json # Returns: {"draft": {"id": "...", "status": "pending"}} Status values: pending - Waiting for human approval approved - Approved, being sent rejected - Rejected by human sent - Successfully sent ### List Drafts List all drafts with optional status filter. postwall drafts # All drafts postwall drafts --status pending # Only pending drafts postwall drafts --json # JSON format ### Periodic Email Checking # Check if there are new emails count=$(postwall check) if [ "$count" -gt 0 ]; then # Process new emails postwall inbox --json | process_emails fi ### Batch Process Emails (Metadata Only) When you only need email metadata (sender, subject, date) and don't need the full body: # Get email list with metadata emails=$(postwall inbox --json) # Process metadata (e.g., filter by subject or sender) ids=$(echo "$emails" | jq -r '.emails[] | select(.subject | contains("Report")) | .id') # Mark processed emails as read without fetching content postwall mark-read $ids ### Send and Track Email # Submit draft result=$(postwall draft --to "user@example.com" --subject "Hello" --body "Content" --json) draft_id=$(echo "$result" | jq -r '.draft.id') approve_url=$(echo "$result" | jq -r '.draft.approveUrl') # Share the approval URL with the user echo "Please approve this email: $approve_url" # Check status later postwall status "$draft_id" ### Refine Draft Based on User Feedback When the user requests changes to a draft before approving: # User asks: "Make the subject line shorter and add a greeting" postwall update "$draft_id" --subject "Q4 Report" --body "Hi Team, Here is the quarterly report..." # The draft is updated, user can now approve from the same URL ### Output Formats All commands support --json for structured output. Use this for scripting and automation. ### Error Handling Commands exit with code 1 on error. With --json, errors are returned as: {"error": "Error message here"} ### Polling for New Emails As an agent, you should periodically check for new approved emails: Run postwall check to get the count of unread approved emails If count > 0, run postwall inbox --json to get the list Process each email with postwall read Recommended polling frequency: Every 5-10 minutes during active sessions, or when user mentions expecting an email. Example polling workflow: # Check if there are new emails count=$(postwall check) if [ "$count" -gt 0 ]; then # Fetch and process new emails postwall inbox --json fi ### Notes Emails are only visible after human approval in PostWall dashboard Reading an email marks it as read - it won't appear in subsequent inbox/check calls Drafts require human approval before being sent API key is stored in ~/.postwall/config.json ## Trust - Source: tencent - Verification: Indexed source record - Publisher: casperaiassist - Version: 1.7.0 ## Source health - Status: healthy - Item download looks usable. - Yavira can redirect you to the upstream package for this item. - Health scope: item - Reason: direct_download_ok - Checked at: 2026-05-07T08:38:34.120Z - Expires at: 2026-05-14T08:38:34.120Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/postwall) - [Send to Agent page](https://openagent3.xyz/skills/postwall/agent) - [JSON manifest](https://openagent3.xyz/skills/postwall/agent.json) - [Markdown brief](https://openagent3.xyz/skills/postwall/agent.md) - [Download page](https://openagent3.xyz/downloads/postwall)
