 ### Setup environment
 ​
 Now tweak deployment settings by modifying environment variables. You have to fix all variables marked as required in this list of [environment variables](../administer/environment.md). Some of the most common issues with custom deployments are listed in the [troubleshoot](../troubleshoot/index.md) section.
+
+### Test deployment
+
+In order to test your deployment there are some utility commands to perform basic checks.
+
+Overall basic check on server configuration:
+
+```shell
+$ docker exec merginmaps-server flask server check
+```
+
+Output will be similar to the next snippet. The utility will try to provide some background information if some needed environment variable is missing or wrongly set (ex: `MERGIN_BASE_URL`)
+
+```shell
+  # Server health check
+
+  Mergin Maps edition: Enterprise Edition
+  Mergin Maps version: 2025.2.0  
+  Error: No base URL set. Please set MERGIN_BASE_URL environment variable
+  Error: No contact email set. Please set CONTACT_EMAIL environment variable
+  Database initialized properly
+  Celery running properly  
+```
+
+To test email configuration:
+
+```shell
+$ docker exec merginmaps-server flask send-check-email --email me@myorg.com
+```
+
+By default, email notifications are disabled, so output will be similar to this:
+
+```shell
+    # Sending check email to specified email address me@myorg.com.
+
+  Error: Sending emails is disabled. Please set MAIL_SUPPRESS_SEND=False to enable sending emails.
+
+```
+
+To enable them, set variable `MAIL_SUPPRESS_SEND` in accordance to above and fill all `MAIL_*` related variables with your company SMTP server configuration.
