Email Queue Pattern

Process emails asynchronously with database-backed queues for reliable delivery, automatic retries, priority levels, and scheduled sending.

What's Included#

  • Database-backed email queue with priority levels and scheduling
  • Queue worker for processing pending emails in order
  • Automatic retry logic with configurable max attempts and backoff
  • Scheduled email delivery for reminders and digests
  • Batch processing for newsletter distribution
  • Dead letter handling for permanently failed emails

Via AI Assistant#

Ask your AI assistant:

  • "Use the email queues pattern from Bootspring"
  • "Apply the Bootspring email queues pattern to my project"

Key Considerations#

  • Never send emails synchronously in request handlers; always queue for async processing
  • Implement exponential backoff for retries to avoid overwhelming the email provider
  • Set a maximum retry count and move permanently failed emails to a dead letter queue
  • Process high-priority emails (password resets) before low-priority ones (newsletters)
  • Monitor queue depth and processing latency to detect delivery issues early
