Remove Slack Integration and Replace with Email Notifications

Overview

This PR completely removes the Slack integration from the Helper codebase and replaces all Slack notifications with email notifications. All functionality is preserved, ensuring zero functionality loss while eliminating Slack dependencies.

Changes Summary

Phase 1: Replace Slack Notifications with Email Notifications

Overview

This PR implements Phase 1 of migrating from Slack notifications to email notifications. All four notification types (Daily Reports, Weekly Reports, VIP Notifications, and Response Time Alerts) now send emails via Resend instead of posting to Slack channels. The implementation includes a robust email infrastructure with user preference management, modern responsive email templates, and comprehensive test coverage.

Core Logic Implementation

1. Email Notification Service (`lib/email/notifications.ts`)

The core email sending service provides four main functions:

sendDailyReportEmail() - Sends daily mailbox summaries with key metrics
sendWeeklyReportEmail() - Sends weekly team performance reports
sendVipNotificationEmail() - Sends VIP customer message notifications
sendResponseTimeAlertEmail() - Sends alerts for overdue tickets

Key Features:

Uses Resend API for email delivery
Renders React Email components to HTML using @react-email/render
Respects user email notification preferences (opt-in by default)
Handles individual email failures gracefully with Sentry error logging
Returns detailed results including success status and recipient count
Early returns if Resend is not configured or no team members found

2. Team Member Email Management (`lib/email/teamMembers.ts`)

getTeamMemberEmails(notificationType?) - Retrieves team member emails with preference filtering
- Filters out users without email addresses
- Filters out deleted users
- Respects per-notification-type opt-out preferences
- Default behavior: opt-in (includes all users unless explicitly opted out)
getTeamMembersWithPreferences() - Returns team members with their full preference data

3. User Preferences System

Database Schema Changes (db/schema/userProfiles.ts):

Extended preferences JSONB field to include emailNotifications object:

emailNotifications?: {
  dailyReports?: boolean;
  weeklyReports?: boolean;
  vipNotifications?: boolean;
  responseTimeAlerts?: boolean;
}

Default behavior: undefined = opt-in (users receive emails unless explicitly set to false)

4. Job Updates

All existing background jobs have been updated to use email notifications:

jobs/generateDailyReports.ts
- Replaced Slack posting with sendDailyReportEmail()
- Maintains all existing metrics calculation logic
- Handles email sending failures gracefully
jobs/generateWeeklyReports.ts
- Replaced Slack posting with sendWeeklyReportEmail()
- Preserves team member performance tracking
- Includes inactive member alerts
jobs/notifyVipMessage.ts
- Replaced Slack posting with sendVipNotificationEmail()
- Handles both new VIP messages and reply updates
- Includes conversation status (open/closed)
jobs/checkAssignedTicketResponseTimes.ts
- Replaced Slack alerts with sendResponseTimeAlertEmail()
- Maintains threshold-based alerting logic
jobs/checkVipResponseTimes.ts
- Replaced Slack VIP alerts with sendResponseTimeAlertEmail()
- Preserves VIP-specific response time tracking
lib/email/vipNotifications.ts
- New helper function updateVipMessageOnClose() for closed conversation notifications
- Sends email when VIP conversations are closed

Email Templates & UI Consistency

All email templates are built using React Email components and styled to match the application's design system. The templates are located in lib/emails/:

Design System Consistency

Color Scheme: Uses the application's mahogany red primary color (hsl(0, 67%, 17%)) from globals.css
Typography: Consistent font stack matching the application (-apple-system, BlinkMacSystemFont, 'Segoe UI', ...)
Spacing: Modern card-based layout with consistent padding and margins
Visual Hierarchy: Clear section separation with proper heading sizes and weights

Responsive Design

All templates are fully responsive and mobile-friendly:

Viewport meta tags for proper mobile rendering
Flexible container widths (max-width: 600px)
Responsive padding and spacing
Images with maxWidth: "100%" for mobile compatibility
Font smoothing for better readability

Template Files

lib/emails/dailyReport.tsx
- Modern header with mahogany red background
- Large metric displays for key numbers (open tickets, tickets answered)
- Card-based sections with borders and subtle shadows
- Conditional display of optional metrics (over $0 tickets, reply times)
- Call-to-action button linking to dashboard
lib/emails/weeklyReport.tsx
- Weekly summary header
- Highlighted total replies metric
- Team member performance breakdown with individual counts
- Inactive member alerts with warning styling
- Dashboard link
lib/emails/vipNotification.tsx
- VIP badge in header with status indicator
- Customer information card
- Original message display with proper formatting
- Reply message section (when applicable)

lib/emails/responseTimeAlert.tsx
- Alert-style header with destructive color
- Summary card showing overdue ticket count
- List of overdue tickets with subject and time
- Truncation for large lists (shows first 10, indicates remaining count)
- Dashboard link

Common Template Features

Header Section: Branded header with primary color background
Footer Section:
- Preference management links
- Helper logo with proper attribution
- Consistent styling across all templates
Error Handling: All dynamic content is safely rendered
Accessibility: Proper semantic HTML and alt text for images

Technical Details

Dependencies

Resend: Email delivery service
@react-email/render: Renders React components to HTML
@react-email/components: Email-safe React components

Environment Variables Required

RESEND_API_KEY - Resend API key for email sending
RESEND_FROM_ADDRESS - Sender email address

Error Handling

Individual email failures are logged to Sentry but don't fail the entire batch
Early returns if Resend is not configured
Graceful handling of missing team members

Performance

Parallel email sending using Promise.all()
Efficient database queries with proper joins
React Email components are pre-rendered to HTML before sending

Migration Notes

Backward Compatibility: All existing job logic remains unchanged; only the notification delivery method changed
No Breaking Changes: The migration is transparent to end users; they simply receive emails instead of Slack messages
