Line breaks in emails

Is ther a way to insert line breaks into emails? My current script is (thank you Steven!):

let sender := userEmail();

let BCCrec := userEmail();

let receiver := Employee.Email;

let subj := "My subject";

let body := “This is where I would like multiple line with line breaks. Line 1. Line 2.  And line 3.”;

let att1 := 'myatt1';

let att2 := 'myatt2';

sendEmail({

from: sender,

to: receiver,

bcc: BCCrec,

subject: subj,

text: body,

attachments: [att1, att2]

})

I tried a rich field text as body, but the html tags showed in the email.
