How to email multiple recipients in sendgrid v3 node.js

问题

Can someone help me send an email to multiple recipients in sendgrid v3 + node.js? I've noticed that when I enter several email addresses in the to field, only the first email address receives the email. The email addresses after the first one do not receive the email:

send: function(email, callback) {
    var from_email = new helper.Email(email.from);
    var to_email = new helper.Email('emailUser1@gmail.com,emailUser2@gmail.com,emailUser3@gmail.com');
    var subject = email.subject;
    var content = email.content
    var mail = new helper.Mail(from_email, subject, to_email, content);
    var sg = require('sendgrid')(process.env.SENDGRID_API_KEY);
    var request = sg.emptyRequest({
      method: 'POST',
      path: '/v3/mail/send',
      body: mail.toJSON(),
    });

    sg.API(request, function(err, res) {
        console.log(res);
        if(err) {
            console.log('---error sending email:---');
            console.log(err);
            console.log(err.response.body);
            callback(500);
        } else {
            callback(200);
        }
    });

}

In the example above, only emailUser1@gmail.com receives the email; emailUser2@gmail.com and emailUser3@gmail.com do not receive the email.

Can someone help?

Thanks in advance!

const sgMail = require('@sendgrid/mail');
module.exports.send = function () {
    sgMail.setApiKey('XYZ');
    const msg = {
        to: ['abc@gmal.com', 'xyz@gmail.com'],
        cc: ['test@gmail.com', 'testing@gmail.com'],
        from: 'no-reply@mail.total.fr',
        subject: 'Subject of mail',
        html: 'html body',
        text: 'text message'
    };
    // console.log('message in mail :: ', msg);
    sgMail.send(msg).catch(console.error);
};

Are you using SendGrid's Helper Library? You're going to want to leverage Personalizations.

If you want the recipients to see each other, you should name & populate each of the recipients within a single Personalization object. If you don't want them to see each other, and want them to each receive the message distinctly, you'll want to make a new Personalization object for each distinct recipient group.

Sendgrid API V3

Hope this helps.

https://www.npmjs.com/package/sendgrid-v3-node

Example: https://runkit.com/embed/ne9asbfj59fr

var sendgrid = require("sendgrid-v3-node")

const mailOptions = {
    sendgrid_key: 'SENDGRID_KEY',
    from_email: 'FROM_EMAIL',
    from_name: 'FROM_NAME',
    to: ['TO_EMAIL1', 'TO_EMAIL2']
};

mailOptions.subject = 'SUBJECT';
mailOptions.content = 'CONTENT';
sendgrid.send_via_sendgrid(mailOptions).then(response => {
    console.log(response);
});
