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.

​

Getting Started

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.

​

DKIM (DomainKeys Identified Mail)

DKIM options can be used in order to sign messages sent using Custom SMTP with DKIM keys.

Those options are:

• DKIM Domain
• DKIM Private Key
• DKIM Key Selector
