When to Use Mail Merge in Outlook

Mail Merge excels for generating multiple similar documents or emails with unique details per recipient. Emails share the same body, format, and graphics, but insert personalized elements like names, addresses, or subjects.

Pro tip from experience: Ideal for targeted job searches with employer-specific details.

The process combines:

  • The main document (Microsoft Word for the email body).
  • The data source (Outlook Contacts or Excel for recipient details).
