Email And The Eyes...

Simple question.

How do I make sure that the person receiveing my email will see it the way I have written/designed it? The way I would like them to see it?

The reason I ask is this... sometimes when I get a reply back, the reply also has my original message with it and it seems as though it's not spaced correctly or indented correctly.

Anyone have any suggestions?

I read somewhere that keeping each line to 65 characters or less will solve this problem.

Don't know.

How can I find out?

And...

How can I find out for ANY email program?

Thanks to any and all that reply.
