Trying to invite a friend for MB and set-up an account using the Reward a Friend/Refer a Friend link: https://www.joinmarriottbonvoy.com/f...ode=EN&source=

However, all emails sent are not arriving. Tried multiple email addresses and domains though never received the invite. Emailed customer assistance however they could not help me. Before trying to set-up such account over phone, any tips? Seems like the form is not completely working here...
