Sending even a 1 Mbyte attachment would block some mail boxes and immediately alienate the very people who's support you are seeking.
Set up a website and email a link to the website, with a brief introduction saying who you are, and why you are sending the email. That way, people can visit the website if it interests them, and download a PDF file to print out a petition. Sending and receiving a 1K email is a lot easier than sending 45 Mbytes.
Keep the home page simple and to the point. Keep most graphics small. If you need a large graphic (more than 50K) put a link, "click here to enlarge" or similar.
