• Gmail Quota Management: Graceful handling of sending limits
• Network Failures: Retry logic for temporary connectivity issues
• Permission Errors: Clear error messages for authorization issues
• Logging System: Dedicated error sheet for debugging

Edge Cases Handled

• Partial Data Entry: Waits for complete information before processing

• Empty Cells: Validates all required fields are present
• Header Row Edits: Ignores changes to column headers
• Wrong Sheet Edits: Only processes the designated "Leads" sheet

🛠 Technical Implementation

Architecture

Google Sheet (Data Source)
    ↓ onEdit Trigger
Google Apps Script (Processing Engine)
    ├── Slack API (Team Notifications)
    └── Gmail API (Prospect Communications)

Key Components

1. Trigger System

function onEdit(e) {
  // Validates edit event and sheet
  // Checks for complete row data
  // Prevents duplicate processing
  // Handles all edge cases
}

2. Validation Engine

function isRowComplete(sheet, row) {
  // Ensures all 5 fields are filled
  // Validates email format
  // Returns boolean for processing decision
}

3. Slack Integration

function notifyTeam(leadInfo) {
  // Formats rich message blocks
  // Implements retry logic
  // Handles rate limiting
  // Includes sheet access button
}

4. Email System

function emailProspect(leadInfo) {
  // Templates personalized messages
  // Manages Gmail quotas
  // Sets proper reply-to addresses
  // Handles delivery failures
}

Error Resilience

Slack API Rate Limiting

let attempts = 3;
while (attempts > 0) {
  try {
    // API call
    if (responseData.error === 'rate_limited') {
      Utilities.sleep(2000); // Wait 2 seconds
      attempts--;
      continue;
    }
  } catch (error) {
    // Retry logic
  }
}

Duplicate Prevention

function isDuplicate(sheet, leadInfo, currentRow) {
  // Checks existing emails
  // Validates processing status
  // Prevents double notifications
}
