Mail Merge involves combining a main document with a data source to create personalized documents. The process typically includes these steps: 1. Select Document Type: Choose the type of document you want to create, such as a letter, email message, or labels. 2. Select Starting Document: Use the current document as the main document or start from a template. 3. Select Recipients (Data Source): Choose an existing list of recipients, create a new list, or select from Outlook contacts. This list contains the variable information (e.g., names, addresses). 4. Write Your Letter/Document: Add the content that will be the same for all recipients. 5. Insert Merge Fields: Place placeholders (merge fields) in your main document where you want the information from your data source to appear (e.g., <<Name>>, <<Address>>). 6. Preview Your Letters: Review the merged documents to ensure the data is correctly inserted and formatted. 7. Complete the Merge: Finish the process by merging the data into the main document. You can then print the documents, send them as emails, or save them as individual files. That's 2 down. 3 left today — send the next one.
