Send Multiple Emails with Personalizations

Personalizations are an array of objects, each representing a separate email, that allow you to customize the metadata of each email sent within a request. The below example shows how multiple emails, each with varying metadata, are sent with personalizations.

Refer to the Sendgrid documentation for more details about personalizations.

const sgMail = require('@sendgrid/mail');
const sgHelpers = require('@sendgrid/helpers');
const Personalization = sgHelpers.classes.Personalization;

sgMail.setApiKey(process.env.SENDGRID_API_KEY);
const msg = {
    from: 'sender1@example.org',
    subject: 'Hello world',
    text: 'Hello plain world!',
    html: '<p>Hello HTML world!</p>',
    personalizations: []
};

const personalization1 = new Personalization();
personalization1.setTo(['recipient2@example.org', 'recipient3@example.org']);
personalization1.setCc('recipient4@example.org');
msg.personalizations.push(personalization1);

const personalization2 = new Personalization();
personalization2.setTo(['recipient5@example.org', 'recipient6@example.org', 'recipient7@example.org']);
personalization2.setFrom('sender2@example.org');
personalization2.setCc('recipient8@example.org');
msg.personalizations.push(personalization2);

const personalization3 = new Personalization();
personalization3.setTo('recipient9@example.org');
personalization3.setFrom('sender3@example.org');
personalization3.setCc('recipient10@example.org');
personalization3.setSubject('Greetings world');
msg.personalizations.push(personalization3);

sgMail.send(msg);
