One click “Export statistics” that would export an XLSX with multiple sheets.
  1. Campaign Performance (table of stats)
  2. Opens Performance (list of open email addresses, contact names, company names, event timestamp)
  3. Clicks Performance (list of click email addresses, contact names, company names, link clicked, event timestamp)
Or if Excel workbook is too fiddly, separate csv export button as you have now, but with the option to select the fields you want in your export.
