sending newsletter using mail merge (1 Viewer)

Hi All

I am not able to solve a problem and would really appreciate if anyone can help me. I have a table that contains duplicate records i.e two people living at same address and I want to send one newsletter at one address. Please find attached a copy of excel sheet containing the exact data. If I use mail merge for this sheet then two letters are going at the same address . But I want to merge those records having the same address so that one newletter can be sent to one address.

Thank you in advance for any assistance.

Regards
Aman
