Configure SMTP for outbound emails

Google Cloud Platform doesn’t allow SMTP traffic through default ports: 25, 465, 587. Check Google cloud documentation to learn how to use a VPN to bypass these restrictions or use a different port for sending emails from your application.

To configure the email settings:

  • Click “Dashboard” in the upper right corner of your concrete5 toolbar
  • Click the “System & Settings -> SMTP Method” menu item.
  • Set the values for the SMTP account as below, assuming a Gmail account:

    • Send Mail Method: External SMTP Server
    • Mail Server:
    • Username:
    • Password: PASSWORD
    • Encryption: TLS
    • Port: 587

    Replace the above values with settings specific to your SMTP server. If using Gmail, replace the USERNAME and PASSWORD placeholders with correct values for your Gmail account.

    Here is an example:

To configure the application to use other third-party SMTP services for outgoing email, such as SendGrid, refer to the FAQ.

NOTE: If you are using Gmail as the outbound email server and have experienced issues trying to send emails correctly, check the Gmail SMTP troubleshooting page to learn the causes of these issues and how to solve them.
