Mail Merge

Mail Merge

I have created a mail merge doc but if I click on multiple contacts to send  it to it does not send. It says it sends but I do not receive the email and it is not in my spam folder. If I click my own contact and mail merge it sends to me. 

What am I doing wrong? 

Oh, and I do see each document when I preview so they are all there to be sent and says it sends but ... nope. 

Thank you,

Marty Mason
