How do you create a mailer?

[Sean Gover]

Maybe I'm searching BP with the wrong words but I can't find any articles or posts on how to create the actual design for a post card mailer that I can upload to a mass mailer site.

Are you creating the post card from scratch in a word document?

If importing an existing image or copying ideas from other mailers, how are you editing the image.

Any useful tips would be appreciated.

Thanks

Sean
