Nodemailer multiple recipients

To send the mail to multiple users you have to place them in a data type String, separated by commas, an example

const arrayUsersMail = ['emailOne@example.com', 'emailTwo@example.com', 'emailThree@example.com', 'emailFour@example.com' ]const stringUsersMail = arrayUsersMail.join(', ')nodemailerMailgun.sendMail({from: 'myemail@example.com',to: stringUsersMail,subject: 'Event Invitation',html: renderToString(<InvitationEmail from="myemail@example.com" to="WHAT HERE" eventId={eventId} />)

})

While @Potier97's answer is correct, I strongly recommend you instead send each recipient a separate e-mail (aka loop through your list of recipients and call sendMail for each). This is because sending an e-mail to multiple recipients means each recipient get the exact same e-mail. The can also see all the other recipients and can Reply to all. I don't know about your specific use case but it's very unlikely that you actually want to do this

const emails = ['email1@gmail.com', 'email2@gmail.com'];for (const email of emails) {  nodemailerMailgun.sendMail({    from: 'myemail@example.com',    to: email,    subject: 'Event Invitation',    html: renderToString(<InvitationEmail from="myemail@example.com" to={email} eventId={eventId} />)  })}
