# Email

Under **Settings → Application Settings → Email**, admins can set up SMTP (Simple Mail Transfer Protocol) configurations in Tellius. These settings are essential for sending out system-generated emails such as alerts, notifications, anomaly updates, and scheduled report exports.

* **Server**\
  Enter the SMTP server address used to send emails.
* **Port**\
  The port through which Tellius will communicate with your SMTP server.\
  Common values:
  * `465` for SSL
  * `587` for TLS
* **From Email**\
  The sender's email address that will appear in the "From" field of emails sent by Tellius.
* **Authentication** \
  Enable this if your SMTP server requires login credentials to send emails. Most providers (like Gmail, Outlook, etc.) require authentication.
* **Secure Connection** \
  Ensures emails are sent securely using encryption (SSL/TLS). Always recommended for data privacy and protection.
* **Security Type**\
  Select the encryption method used by your email provider:
  * **SSL** (Secure Sockets Layer): Uses port 465.
  * **TLS** (Transport Layer Security): Uses port 587.
* **Username (Optional)**\
  Enter the username for SMTP login—usually the same as the "From Email".\
  This is required if **Authentication** is enabled.
* **Password (Optional)**\
  Enter the SMTP password or an app-specific password. This field is secured and masked.

### Run Validation

1. After entering all necessary details, click on **Run Validation**.
2. Tellius will test the SMTP connection using the provided information.
3. A success or error message will confirm whether the configuration works.

If validation fails:

* Double-check credentials.
* Ensure correct port and security type.
* Confirm firewall or email provider isn't blocking connections.
