Hello, Sometimes the spacers don't download as blank spaces, and instead, I get a red x in a box in my Outlook (a non-downloadable image), or a lightly outlined box in my iPhone Yahoo email. I fed back to your customer service rep. She advised that I give you feedback here too. She was under the assumption that the coding of the spacers is being read by Outlook/Yahoo as an image that can't be downloaded. Can you please fix this? Thank you.
