Lotus Notes R5

I am preparing several sets of emails to be sent to clients. These emails are actual duplicates of each other with only one minor change in the body of the message. I have already created the first set of emails (120 emails in Draft mode) and would like to know if there is a feature in Lotus Notes that allows for duplication of the email message, including the email address. I have to set up 120 emails 5 times. I did a merge and copied and pasted from Word to Lotus Notes, 120 times. I cannot merge to emails, since there are attachments that must be included with each email. I am hoping that there is a better way to accomplish the task I have to complete.

Thanks,

Mary
