SigNoz allows you to configure email settings for sending email Invitations. Depending on the version you're using, you can choose which variables to configure.
Version greater than 0.84.x
| Environment variable | Description |
|---|---|
SIGNOZ_EMAILING_ENABLED | Enable or disable emailing |
SIGNOZ_EMAILING_TEMPLATES_DIRECTORY | The directory containing the email templates. This directory should contain a list of files defined at pkg/types/emailtypes/template.go |
SIGNOZ_EMAILING_SMTP_ADDRESS | SMTP server address (host:port) |
SIGNOZ_EMAILING_SMTP_FROM | Sender address |
SIGNOZ_EMAILING_SMTP_HELLO | Hello message to use for the SMTP server |

SIGNOZ_EMAILING_SMTP_AUTH_IDENTITY | Identity to use for the SMTP server |
SIGNOZ_EMAILING_SMTP_TLS_ENABLED | To enable TLS. It should be false in most cases since the authentication mechanism should use the STARTTLS extension instead. |
SIGNOZ_EMAILING_SMTP_TLS_INSECURE__SKIP__VERIFY | Whether to skip TLS verification |
SIGNOZ_EMAILING_SMTP_TLS_CA_FILE_PATH | Path to CA file |

If you are using Helm to deploy SigNoz, you need to configure these variables as lowercase keys under the signoz.env block in your values.yaml (for example, signoz_emailing_smtp_address).
Also note that these variables only configure SMTP for Email Invitations and Forgot Password functionality. If you want to configure SMTP for alert notifications, you must separately configure Alertmanager. See Alertmanager Configuration and Email Alert Channels.
Versions less than or equal to 0.84.x
To enable email, you need to set the following environment variables
SMTP_ENABLED: Enable SMTP for sending email invitations.SMTP_FROM: The email address from which the invitations will be sent.SMTP_HOST: The SMTP host obtained from your email provider.SMTP_PORT: The SMTP port obtained from your email provider.SMTP_USERNAME: The SMTP user obtained from your email provider.SMTP_PASSWORD: The SMTP password obtained from your email provider.
If you are using a version less than or equal to 0.75.0, you need to set these environment variables specifically for the query-service component. As Starting from v0.76.0, multiple services (Query Service, Frontend, and Alertmanager) were combined into a single signoz binary/image.
