Email Alerts

Techulus Cloud can send email alerts when things go wrong. Alerts are delivered via SMTP to a configurable list of recipients.

Alert Types

Alert	Trigger
Server offline	A server stops reporting to the control plane
Build failure	A container image build fails
Deployment failure	A deployment fails during rollout
Deployment moved	A deployment is moved to a different server

Add the following environment variables to the control plane:

Variable	Description
`SMTP_ENABLED`	Set to `true` to enable alerts
`SMTP_HOST`	SMTP server hostname
`SMTP_PORT`	SMTP port (e.g., `587`)
`SMTP_USERNAME`	SMTP authentication username
`SMTP_PASSWORD`	SMTP authentication password
`SMTP_ENCRYPTION`	`starttls` or `tls`
`SMTP_FROM_NAME`	Sender display name (e.g., `Techulus Cloud`)
`SMTP_FROM_ADDRESS`	Sender email address
`SMTP_TIMEOUT`	Connection timeout in milliseconds (default: `10000`)
`SMTP_ALERT_EMAILS`	Comma-separated list of recipient email addresses

Works with any SMTP provider — Amazon SES, Resend, Mailgun, Postmark, or your own mail server.
