Why are SendGrid logs showing incomplete entries?

I have SendGrid set up to capture incoming messages and route them to my webhook endpoint. This morning I tested by sending 6 messages through the system. All 6 messages successfully reached my webhook and I can confirm they were processed.

However when I check the SendGrid logs I’m seeing inconsistent entries:

  • Message 1: Shows Delivered/Processed/Bounced status
  • Message 2: Shows Delivered/Processed/Bounced status
  • Message 3: No log entry at all
  • Message 4: Only shows Delivered status
  • Message 5: No log entry at all
  • Message 6: Shows Delivered/Processed status

I can verify all messages were sent successfully because they appear in my Gmail outbox and my webhook debugging showed all 6 triggers fired correctly.

What could cause the logging system to miss some entries or show partial information like this?

Classic SendGrid webhook issue. Their event webhooks are asynchronous and can be delayed or fail completely. The dashboard logs depend on these webhooks, so they don’t always show up in real-time or in the right order. I’ve hit this before - SendGrid’s logging system gets spotty during high traffic or when their infrastructure hiccups. Your webhook got all 6 messages, so the actual email processing worked fine. It’s just their logging that’s inconsistent. Check if you’ve got webhook retries enabled in your SendGrid settings. Sometimes the first delivery fails but retries work later, causing log entries to show up hours or days late. I’d wait 24-48 hours to see if those missing entries appear - happens all the time in production.

Yeah, probably just SendGrid’s slow log aggretation again. Their logs pull from different sources and can take forever to sync. I wouldn’t stress about it - your webhook caught everything, which proves delivery worked. Missing entries usually appear later, just wait it out.

I’ve seen this exact issue with SendGrid’s activity feed before. It’s usually their event tracking architecture causing problems. SendGrid processes emails across multiple servers and pulls activity logs from different sources - they don’t always sync up properly. Since your webhook caught all six messages, the core functionality works fine. I’ve noticed partial log entries happen when some events get captured but others disappear between SendGrid’s internal systems. The “Processed” event is especially prone to this since it runs on separate tracking infrastructure. You can try enabling detailed event notifications in your mail settings - it might capture more complete data, but won’t fix the sync issues. The logging inconsistency is annoying but doesn’t mean delivery failed. Your webhook confirmations are what actually matter.
