thanks for all your replies...i know it's our bad because we failed to include email address on the original application

. I was thinking to just send a letter to manila visa office and request to add his email address as a contact information. Is this okay? Second question is, I just got approved as a sponsor so I dont know how long his application will be send to manila visa office.Should I wait for a couple of months before we send the request that he wants to add his email address?? thanks again..
