@dalehileman,
Can you describe how you are saving your emails for future reference? Are you using an email program to do it? If so, which one and how are you doing it?
If not, are you copying the email and then pasting it into a file?
There may be better methods to do this.
One being to navigate to the website link in the email before saving the email, then save the website as a bookmark. After that you can access the website again via your bookmarks.
