Websites hosted by Templ are configured to send (transactional) e-mails with our SMTP-server automatically.
In some cases the SMTP settings may be needed, e.g. to configure email sending via Gmail, then those settings can be found in the Templ Panel under Email - SMTP Settings.
When sending emails using our SMTP server it's always recommended to make sure you have added our SPF and DKIM records, as well as verified your domain in order to achieve the best possible email deliverability.
