Email sending is critical: order confirmations, password resets, important notifications. An email service outage can have serious consequences.
Monitor your email provider APIs to detect problems before your users.
Popular Email Providers
- SendGrid: REST API at api.sendgrid.com. Status page: status.sendgrid.com.
- Mailgun: REST API at api.mailgun.net. Endpoint /v3/domains to validate.
- AWS SES: AWS service, monitor via API or CloudWatch.
What to Monitor
- API availability: the main API must respond and accept requests.
- Quota: verify you haven't reached your sending limits.
- Deliverability: bounces and complaints may indicate problems.
