If you want to debug failed emails without building your own dashboard, look for email sending providers with built-in logs, events, and deliverability tools. Good options include:
Popular providers with strong debugging/observability
- SendGrid — message activity feed, event webhooks, suppression lists, bounce/complaint tracking.
- Mailgun — detailed logs, failed delivery reasons, route testing, events API.
- Postmark — excellent message history, bounce details, delivery status, and templates/logs.
- Amazon SES — cheaper, but debugging is usually done via CloudWatch, SNS, and event publishing rather than a friendly dashboard.
- SparkPost — detailed analytics, engagement and delivery events, suppression management.
- Resend — simple logs, event webhooks, and error visibility, especially nice for developer workflows.
- Mailjet — logs and event tracking with a usable UI.
What to look for
When comparing providers, check whether they offer:
- Delivery/bounce/complaint events
- Searchable message logs
- Reason codes for failures
- Webhook support for real-time alerts
- Suppression/bounce lists
- Test sending or sandbox tools
- API access to raw event data
Best picks by use case
- Best for detailed debugging: Mailgun, Postmark, SendGrid
- Best for simple developer UX: Postmark, Resend
- Best if you want low cost and don’t mind assembling tools: Amazon SES
