You can use a Custom SMTP provider like Nodemailer to send transactional emails through your custom SMTP server to your customers using the Novu Platform with a single API.
To use the Custom SMTP provider in the email channel, you will need to have your personal SMTP server configured and add host, port, user, and password to the Custom SMTP integration on the Novu platform.
You can also provide value true for the secure field if you want the connection to be secure, and if not, leave it empty.
