I'm developing a newsletter in asp.net that will be send to a large quantity of users, so each kilobyte that I can reduce will help a lot in the use of bandwidth consumption, what I do until know is write the aspx excluding some spaces between tags, and before render, i've renamed some controls ids to "-" to save more space. So now, the file has 50kb. I need a file with 25 Kb.

Can anyone teach me any other way do save more space ?

ps.: I Use 3 divs with some data, and 2 repeaters, one inside other, to generate a table with some data for me.

thanks in advance
