Filled In a Scanned document through Edit and sent it in an email, recipient says it's blank.

I am using Adobe Acrobat DC, I scanned in a document and filled it out through the Edit tool. I used a basic font setting-Arial. I save it as a PDF and tried two options as to how it would get opened- Adobe Reader, and Microsoft Edge. I emailed the form to several people and they all told me the form came over blank, and also stated that Adobe Reader wanted them to download a font package. What am I doing wrong? I am not tech friendly so please be nice!
