What Is Photo Keeper ???

This may be perfectly legitimate and harmless; I just checked my e-mail and there is a suspicious message from a source that I am not familiar with --- Photo Keeper.

If I have joined something that it may be associated with, I am not aware of it. 

I did not open/read the e-mail.

Here is what the description says:



G-Mail has always been pretty good at determining unsolicited messages, but this one is right there at the top of the list.

I am not knowledgeable as to what is and is not dangerous where e-mails are concerned; is there any harm in clicking on a potentially harmful e-mail in order to read it and see what it is ?

I know that one should never open any files that are attached to questionable e-mails.

Thanks for reading.
