Possible Payload inside PDF or HTML files

[Danux <danuxx () gmail com>]

Hi experts,

Is there a way to know if exist a payload inside a PDF or HTML File,

Let me explain the problem, i marketing company is sending me emails
and is able to know if i open, delete, sent to spam or forward the
message so i think there is a payload inside that files.

Let me tell you that the HTML file looks like a normal one without
javascript or obfuscation or another malicious payload, only links and
images,

Is there a tool to look inside PDF files?
Or a Steganos tool to test the images from HTML file?

What you think?

Thanks in advance
