Sending text within a document

I am looking to import text into a e-mail from a document. For example, If I have a document called text1.txt and instead of me having to send it as an attachment and open it up. Is their anyway I can just import that text into the e-mail so I dont have to open it every time?

I have the code for sending an e-mail but I am not sure how to export text from inside a document. Is this possible?

Thanks!
