You may have created a Word mailmerge template within which you have built a section using text boxes. You save the template (including the relevant tags) but when you create the mailmerge campaign and download/print you see that the text box content is blank.
A: You can't include content with text boxes as they are not compatible with our Letters & Labels (mailmerge) module. Find other ways of creating that content but avoid the use of Word text boxes. You might just want to type the text and insert images but don't use text boxes to contain that content.
