<script>
$('.keywordError').hide();
let triggerWords = ['@DOMAIN1', '@DOMAIN2'];
let buttonColor = '#FORM_BUTTON_ID';
function containsBannedWords(input) {
let result = false
triggerWords.forEach(function(triggerWord) {
if (input.toLowerCase().includes(triggerWord)) {
result = true
}
});

$('#EMAIL_FIELD_ID').keyup(function(event) {
if (containsBannedWords(event.target.value)) {
$(event.target).prop('value', "");
