I'm sorry that this is giving you trouble! Basically this means that we have to verify your email address before you send the mailing. If you are not receiving the verification email that is a separate issue in itself. I noticed that you are using a Gmail address. The verification email might be ending up in either your Spam folder or your Promotions folder. Before we take any other actions you should check there and see if you ended up receiving it after all.
If it did not end up in Promotions or Spam please let me know. We will get this figured out for you.
