The text email advert is easy but not recommended

if you don't have pictures you can still make and HTML advert by making some sentences large or bold or colored

then put you website link at the bottom and in the middle of the ad if you have a website that you want them to com to

otherwise , for a text ad just type up some ordinary text and include your website link our email address at the bottom for them to see

When doing a large email campaign, do not provide a phone number that you can be reached directly. Because some of the recipients that may want to be remove may be calling you directly to be removed instead of using the remove link provided. So it is best to provide a voice mail number for them to leave a message if they are interested
