From Feingeist Software:
Millions of emails are sent every single day and in many cases they do not only contain text. Email attachments extend conventional text emails by images, music, documents and even videos. Typically people compose their email text and add their file attachments right before they send the email - if they do not forget to attach. Probably everybody had this feeling before: You just clicked on "Send" in your favorite email client and immediately after realized that you mentioned an attachment iny our email text, but forgot about attaching the described file to the email. What do you do now? You send another email with the files attached and something like: "Here are the attachments - finally."
Forget about these embarrassing emails from now: Install ForgetMeNot and never forget about attaching files again!
