 After that, check the `app/Config/MultiEmail.php` file, and set it up with your email credentials.
 
+## Configuring SMTP in the `.env` File
+
+We recommend setting the configuration for each SMTP email in the `.env` file instead of using `app/Config/MultiEmail`.
+
+For example, you can proceed as follows:
+
+```
+#--------------------------------------------------------------------
+# MULTI-SMTP CONFIGURATION SETTINGS
+#--------------------------------------------------------------------
+
+# email.default.fromName =
+# email.default.fromEmail =
+# email.default.protocol = smtp
+# email.default.SMTPUser =
+# email.default.SMTPPass =
+# email.default.SMTPHost = smtp.gmail.com
+# email.default.SMTPPort = 587
+
+# email.outlook.fromName =
+# email.outlook.fromEmail =
+# email.outlook.protocol = smtp
+# email.outlook.SMTPUser =
+# email.outlook.SMTPPass =
+# email.outlook.SMTPHost = smtp.office365.com
+# email.outlook.SMTPPort = 587
