BookingPress Email Notification

Mail Service

Please select one of the email services to send email notifications.

Options available are:

  • PHP Mail
  • WP Mail
  • SMTP (Simple Mail Transfer Protocol)

Sender Email: This option is used to set the sender name in all email notifications that will be sent from the system.

Admin Email: This option is used to send email notifications to the admin.

SMTP Settings

Let’s understand how to configure SMTP for Gmail, but you can set it for other email services that support SMTP. When you select the SMTP option from “Mail Service”, the below inputs will be displayed.

An Outlook SMTP configuration example:

  • Host Name:
  • Port: 587
  • Secure Connection: TLS
  • Username: Your Outlook email address
  • Password: Your Outlook email password

Note: SMTP configuration details will be different for each SMTP provider. Kindly confirm the details with your SMTP provider.

Once you set the above options, you can test your SMTP connection status. Whether it got successfully connected or not. You can test it by sending a test email to any email address where you can check if the email is received or not.

➤ SMTP Connect() Failed

When facing this error, it usually indicates a problem with establishing a connection to the SMTP server. Here are some common reasons and steps to resolve the issue:

1. Check SMTP Configuration:
Ensure that the SMTP settings, including host, port, username, password, and encryption method, are correctly configured in BookingPress settings.

2. SMTP Server Status:
Confirm that the SMTP server is operational and accepting connections. Contact your email service provider or SMTP host for assistance if needed.

If your SMTP server requires a secure connection (SSL/TLS), ensure that the appropriate option is selected in the Secure connection setting. Choose the appropriate encryption method based on your SMTP server’s requirements.
