I don't think awk oneliners should count as oneliners if they're wider than the screen.
how about this:
Code:
$ awk '{
EOF=0;
for (N=1; (!EOF) && (N<7); N++)
if(!getline A[N]) EOF=1;
if(!EOF)
{
printf("You have an email from %s (%s)\n", A[5], A[6]);
printf("Sub: %s\n", $0);
printf("Desc: %s\n\n", A[1]);
}
}' < data

It just retrieves 6 extra lines per loop to make up the difference so complex logic to print different lines on different loops isn't needed.

EMPTY-PAGE(1) ExactImage Manual EMPTY-PAGE(1)NAME
empty-page - empty page detector of the ExactImage toolkit
SYNOPSIS
empty-page [option...] {-i | --input} input-file
empty-page {-h | --help}
DESCRIPTION
ExactImage is a fast C++ image processing library. Unlike many other library frameworks it allows operation in several color spaces and bit
depths natively, resulting in low memory and computational requirements.
empty-page counts dark pixels of a black and white image and decides with a threshold whether the page is most probably empty, and thus can
be removed from the image processing stream.
OPTIONS -i file, --input file
Read image from the specified file.
-m n, --margin n
Set width of border margin to skip. For speed reasons, the margin has to be a multiple of 8. The default is 16.
-p x, --percentage x
Set fraction of permissible dark pixels. The default is 0.05 (5%).
-h, --help
Display help text and exit.
EXAMPLES
$ empty-page -i test.tif
The image has 75461 dark pixels from a total of 1060992 (7.11231%).
non-empty
EXIT STATUS
The exit status is 0 if the image is mostly white, 1 otherwise.
