The Details
For those who want more, we take on each of the e-mail’s claims in order:
1. "$11 Billion to $22 billion is spent on welfare to illegal aliens each year."
This item is completely false. The link given to "verify" the claim actually leads to an issue brief by the conservative Federation for American Immigration Reform. But the FAIR brief says nothing of the sort. It says: "Each year, state governments spend an estimated $11 billion to $22 billion to provide welfare to immigrants." That’s welfare payments in 2001 to all immigrants – both legal and illegal – plus households including U.S. citizens if they are headed by a person who was born outside the United States.
The site says the FAIR report was last updated in October 2002, but a footnote credits this statistic to a March 2003 report from the Center for Immigration Studies. CIS began as an off-shoot of FAIR. But the CIS report doesn’t actually say anything about $11 billion or $22 billion. And it explains that its references to "immigrant households" include persons here legally and persons born outside the U.S.

False information dies hard. It is very difficult to convince someone of something they think they already know.
