Hi Mike,
I am going to explain you how Mail Merge works in word 2007, ( May I know your version)
Before start mail merging you need to have the details in excel or access (General, I personally opt this to send mails to number of recipients, You need to have TO and From emaill ids to start with )
1. Go to Mailing tab ---> Start Mail Merge
under this you will see Letters, Email Messages, Envelop, Labels, Directory, Step by Step Mail Merge Wizard.
a. Letters / Envelop / Labels : To create multiple Letters / Envelop / Labels from single FROM ADDRESS to multiple TO ADDRESS.
b. Email : Send a single email to multiple address, for example you get the discount coupon from ebay.com to your mail, similarly others will get the same mail, .. this is called MAIL MERGE
2. Select Set by Set Mail Merge wizard (before doing this, hope the content is ready to send the mail, if not please be sure that the content is ready for sending)
3. Select Doc type : Email - Messages (right side of the word doc)
4. Click Next : Starting Document (Right lower bottom of the word doc - Step 1 to 6 )
5. Select Starting Document
5a. Use the current document : Use the current content for sending
5b . Start from a Template : Use predefined Template
5c. Start from Existing Document : Use the existing document which was saved earlier.
in my case I select, USE THE CURRENT DOCUMENT where I have my own content.
7. Next : Select Recipients
8. Select Receipents :
8a. Use an existing list : Use the existing excel or access list (Globally, outlook + Gmail+Yahoo etc)
8b. Select from outlook contacts : send mails to the contacts available in outlook only
8c. Type a new list : enter your own list.
In my case I have taken USE AN EXISTING LIST, which I have the contact email details saved in excel and saved on the computer.
9. Use an existing list : Browse the location of the existing access or excel file for email contacts, a window will open once you upload the sheet saying that the SHEET to be selected. After that another window of recipients will be opened to recheck the email ids present
10. Next Write your email message : Edit the content of the message
11. Preview the message: before shooting mails, have a look at your mail merge
12.Complete the mail merge.
Hope this would help you understand the process of sending mails to others using mail merge.
Like wise, you can print Envelops, Labels and Letters using mail merge
