Question on print and actual aspect ratio

Hi.

First time posting on these forums. Long time reader of them heh.

I am working on an graphic email that is going to be sent out to different companies. Ok to my problem:

I got the image size down enough to be a decent email size. Problem is that I am working at 300dpi in order for the small text on the prints to be legible. Ok now I am using 8x10 inches as size but at 300 dpi is way bigger in pixels so when I insert it into the email the images is huge.

Ok what I am trying to do is:

I want the view size to remain at about 8x10 but I want the dpi to remain at 300 for printing quality

Thanks in advance

maybe try making two images... like a webworthy one for the emails then attach a .psd or the original image at 300dpi
