I’m building a product and need email logs and webhook tracking, what should I use?

If you need email logs and webhook tracking, the best choice depends on whether you want to build it yourself or buy an existing service.

Good options by need

1) If you want a quick, reliable SaaS solution

Use a service that already gives you:

• Email event logs: delivered, opened, clicked, bounced, complained, unsubscribed
• Webhook delivery logs: request/response history, retries, latency, failures
• Searchable audit trail
• Replay / resend for failed webhooks
• API access

Common tools in this category:

• Postmark — excellent for transactional email logs, clean UI, great deliverability
• SendGrid / Mailgun / SparkPost — broader email infrastructure, more features, more complexity
• Hookdeck — very strong for webhook tracking, retries, filtering, replay, observability
• Svix — great if you are sending webhooks to your customers and want managed webhook infrastructure

2) If you’re building the tracking yourself

Use an event pipeline with a database/log store:

• Email events: capture provider webhooks and store them in Postgres / ClickHouse / BigQuery / Elasticsearch
• Webhook events: log inbound/outbound requests with request ID, payload, response code, retries, timestamps
• Add:
  • correlation IDs
  • structured JSON logs
  • a status timeline per message/event
  • replay tooling

This gives maximum control, but takes more engineering.

My practical recommendation

For most products:

• Email: Postmark or SendGrid
• Webhook tracking: Hookdeck or Svix

If you want one stack for both observability and delivery:

• Use Postmark for email
• Use Hookdeck for webhook monitoring/replay

What to choose based on your scenario

• Transactional emails only → Postmark
• Marketing + transactional email → SendGrid or Mailgun
• You need to observe and retry webhooks → Hookdeck
• You send webhooks to customers and need per-customer delivery management → Svix
• You need everything custom and internal → build with DB + log pipeline

Important features to look for

For both logs and webhook tracking, make sure the tool supports:

• event search
• filtering by status and time
• payload inspection
• retries/replay
• alerting
• API export
• retention controls
• compliance/privacy features

If you tell me:

1. whether this is for sending emails, receiving emails, or both
2. whether webhooks are incoming, outgoing, or both
3. your stack (Node, Python, etc.)

…I can recommend a specific setup and architecture.
