Why won't my product export zip files open?

I export my products and get this email. BUT the zip files do not open. Zip files used to always open until starting around February and it’s still happening.

Your products have finished exporting and are ready to download.

### Downloads- products_export_1.zip
- products_export_2.zip

Never mind - opened Gmail to show original - then download original - email opens in a new view to export the zip files.
