Then you have either not configured a system email with SMTP or the configured SMTP is failing or you didn’t configure your outgoing email setting appropriately. First make sure you have a system email with SMTP configured. Next confirm the SMTP credentials by going to the system email under Admin Panel > Emails > Emails, clicking Outgoing (SMTP) tab, ensuring the Status is set to Enable, and clicking Save Changes. Upon clicking Save Changes with the SMTP Status set to Enable the system will attempt to connect and authenticate against the host and port with the configured credentials. If it saves successfully then the SMTP info appears correct. You can then test the SMTP by going to Admin Panel > Emails > Diagnostic. If everything checks out the last step is to confirm the SMTP email you configured is set as the Default System Email, Default Alert Email, and Default MTA under Admin Panel > Emails > Settings.
