OS X Built-in ZIP'per

It’s a pain to send a large file over the Internet, or a horde of smaller ones. Fortunately, OS X has built-in tools to ease this.

Select the file or files, or even a FOLDER of files you want to bundle for shipment in Finder, then select File > Create Archive.

The result is a new file created in the same location of your selected files named "ARCHIVE.ZIP". This smaller compressed file can added to an email attachment and sent down the email pipe.

(NOTE: Not all mail servers are created equal and some companies Mail servers/IT departments will reject anything with a ".zip" attached to it. Double-check that your email made it to the other end safely.)
