Is it true that newsletters in HTML should have a "table-based" layouts?

Question

I read somewhere that when creating a HTML email, you should use the table-based layout. You should not care about creating tableless css based layout. Is that true? I have to create a newsletter layout for my company, but I dont feel confortable writing 3 nested tables.

Answer 1

If you want your HTML-email to look good in most email clients, you should write your HTML as it still was 1999 :)
