Formatit.com is an email formatting and text formatting tool. You will be able to format text to a specified column width while preserving the original paragraph endings.
Simply write your article in Word or whatever word processing software you use, copy and paste into the box at formatit.com, select the number of characters for your column (50, 60, etc.) and submit.
The reformatted text will appear. Now just copy and paste into your email or blog and that’s it.
This is extremely helpful if most of your readers are reading your messages on a smart phone.
