It is possible and easy to send email using SharePoint PnP JavaScript Core Library. You can do it by defining an object based on the EmailProperties interface, and send it using the utility.sendEmail function:
const emailProperties: EmailProperties = {
To: ["[email protected]"],
CC: [],
Subject: "Testing PnP JavaScript send email functionality",
Body: "This email has been sent using JavaScript",
};
pnp.sp.utility.sendEmail(emailProperties).then(() => {
this.domElement.innerHTML = `<p>Email has been sent.</p>`;
});
