I'm trying to reduce our email tooling. What can replace SMTP plus custom logging?

If your goal is to reduce tooling, the main replacement for SMTP + custom logging is usually:

1) An email delivery API with built-in event tracking

Examples: SendGrid, Mailgun, Postmark, Amazon SES + event destination, Resend

These give you:

  • message send API
  • delivery/bounce/complaint events
  • webhook callbacks
  • searchable message logs
  • suppression handling
  • templates and tracking, if needed

This lets you remove:

  • your SMTP client config
  • much of your custom send logging
  • some delivery-status polling/hand-rolled bounce handling

2) A message queue + email service integration

If you need reliability and auditability, pair the email API with:

  • SQS/RabbitMQ/Kafka/Redis queue
  • a worker that sends mail
  • provider webhooks for final status

This replaces “SMTP server + logging” with:

  • queued jobs for send attempts
  • provider event logs for outcome
  • application DB only for business-level email state

3) Provider-native logging instead of custom logs

If your custom logging is mostly for:

  • sent/delivered/failed status
  • recipient history
  • bounce reasons

then many providers’ dashboards/APIs already cover it. You may only need to store:

  • internal message ID
  • recipient
  • template/intent
  • provider message ID
  • final state

What to choose

  • Need simplest replacement: Postmark or Resend
  • Need lots of features and scale: SendGrid or Mailgun
  • Need AWS-native: SES + SNS/EventBridge/Webhooks
  • Need minimal ops and good developer UX: Resend

Important note

If by “SMTP” you mean the transport layer only, you can still send via SMTP to a provider, but you’ll usually get better observability by using the provider’s HTTP API plus webhooks rather than raw SMTP.

A practical replacement pattern

  1. App writes an email job record to DB
  2. Worker sends via provider API
  3. Provider returns message ID
  4. Provider webhook updates delivery/bounce/complaint status
  5. Your DB becomes the single source of truth for app-facing email state

If you want, I can recommend a specific replacement based on:

  • your volume
  • transactional vs marketing email
  • AWS/GCP/Azure preference
  • whether you need archiving/compliance logs
