Sending to multiple recipients MuleSoft Email SMTP

I have been trying to send to multiple recipients but to no avail. Currently I define a transform to split then join the recipient string then pass it to the email connector, but it fails saying

Error while sending email: Error while creating email1@domain.com,email2@domain.com InternetAddress

The original transform is defined as below:

if((emailString as String) contains "," )
        (emailString as String) splitBy "," joinBy ","
    else if(emailString != "" and emailString != null)
        [emailString]
    else
        null

I am wondering if there is a bug or special case I have not seen while checking the documentation.

Solution

  • You are splitting the string containing emails addresses but then you are joining the resulting items back into a string. Just pass the resulting array to the connector. You probably don't need the other cases. splitBy() already returns a single element if the split character is not found and returns null if the input is null.

    Example:

    <email:send toAddresses="#[vars.emailString splitBy(&quot;,&quot;)]" ... >
