Ask HN: MailChimp not working

Has anyone had experience with MailChimp failing to verify your email domain? I have collected a list of email signups and the first time that I am trying to send a campaign I am prompted to verify my email domain before I can send the campaign. The trouble is that MailChimp claims to send me a verification code but I am not receiving it on my end. Needless to say that I have contacted MailChimp support over more than 24 hours ago but no response.. I basically have an account that I can do nothing with it. Anyone with a similar experience?
