Protractor Fetching Email with Mail Listener: TypeError: deferred.fulfill is not a function

it fixes the issue The problem seems to be the protractor promise API. Not sure which version of protractor you are using.
In any case, as you are using async/await why not use Promise directly instead of relying on Protractor promises?
code :
export class MailHelper {
  static getLastEmail() {
    const globalAny: any = global;
    return new Promise((resolve, reject) => {
      globalAny.mailListener.on('mail', function (mail, seqno, attributes) {

I hope this helps . mail-listener2 works on the IMAP protocol. It works like your Outlook mail client to receive mails. If your mail server supports the IMAP IDLE protocol, you should get message notifications from the servers as a "push notification" rather than a response to continuous polling.

around this issue I usually use the map, filter, action/assert pattern. It looks something like this:
code :
element.all(locator).map(function(elm, index) {
  // Get the value you are interested in finding and return the element too.
  return {
    elm: elm,
    text: elm.getText(),
    index: index
}).then(function(list) {
  // Find your text here. Otherwise fail.
  for(var i = 0; i<list.length; i++) {
    if(list[i].text === name) {
      return list[i].elm;
  throw new Error('Solution not found');
}).then(function(elm) {
  // Perform an action on the element you found.

Hope that helps This is something I've solved recently. Hope the solution would also apply for your use-case.
code :
npm install mail-listener2 --save-dev
onPrepare: function () {
    var MailListener = require("mail-listener2");

    // here goes your email connection configuration
    var mailListener = new MailListener({
        username: "imap-username",
        password: "imap-password",
        host: "imap-host",
        port: 993, // imap port 
        tls: true,
        tlsOptions: { rejectUnauthorized: false },
        mailbox: "INBOX", // mailbox to monitor 
        searchFilter: ["UNSEEN", "FLAGGED"], // the search filter being used after an IDLE notification has been retrieved 
        markSeen: true, // all fetched email willbe marked as seen and not fetched next time 
        fetchUnreadOnStart: true, // use it only if you want to get all unread email on lib start. Default is `false`, 
        mailParserOptions: {streamAttachments: true}, // options to be passed to mailParser lib. 
        attachments: true, // download attachments as they are encountered to the project directory 
        attachmentOptions: { directory: "attachments/" } // specify a download directory for attachments 


    mailListener.on("server:connected", function(){
        console.log("Mail listener initialized");

    global.mailListener = mailListener;

onCleanUp: function () {
function getLastEmail() {
    var deferred = protractor.promise.defer();
    console.log("Waiting for an email...");

    mailListener.on("mail", function(mail){
    return deferred.promise;
describe("Sample test case", function () {

    beforeEach(function () {

    it("should login with a registration code sent to an email", function () {

        browser.controlFlow().await(getLastEmail()).then(function (email) {
            expect(email.subject).toEqual("New Registration Code");

            // extract registration code from the email message
            var pattern = /Registration code is: (\w+)/g;
            var regCode = pattern.exec(email.text)[1];

around this issue If i understand it right, you can now use the native promises (i hope it's the correct link). Like this way:
code :
browser.s2.util.unzip = function(report){
    return report.then(function(report){
        return new Promise(function(resolve, reject){
                // reading archives
                var zip = new AdmZip(report);
                var zipEntries = zip.getEntries(); // an array of ZipEntry records
                zipEntries.forEach(function(zipEntry) {
                    zipEntry.d =  zip.readFile(zipEntry);
