If you need to handle spikes in email volume, you should use a queue / message broker between your email-producing system and the actual email-sending worker.
Why
A queue helps you:
- Buffer spikes so your app doesn’t get overloaded
- Process emails asynchronously
- Retry failures safely
- Scale workers horizontally during high load
Common options
- AWS SQS + worker consumers
- RabbitMQ
- Apache Kafka (if you need very high throughput/event streaming)
- Google Cloud Pub/Sub / Azure Service Bus
- For simpler setups: Redis-backed job queues like Sidekiq, BullMQ, or Celery
Typical pattern
- App creates an email job
- Job is pushed to a queue
- Worker service pulls jobs and sends emails at a controlled rate
- Failed jobs are retried or sent to a dead-letter queue
If you want, I can recommend the best option based on your stack (Node, Python, Java, AWS, etc.).
