Advertisements on email page constrict the space allotted for actual reading of email (i.e., 1/3 of the page on the right hand side. Also noticed was slower loading of email. Perhaps you could arranged to have advertisements displayed across the entire width of the screen at the bottom of each page, perhaps at 1/4 or 1/5 of the screen's bottom. I realize that advertisement is important to maintaining business; but frustrating users is an impediment to business - i.e., no one to read the advertisements.
