Get me email, spam, and web statistics

Hi, this is a simple project, I need these statistics from a reliable source, please cite the source as well, ideally it is a reputable research paper: -How many emails are received in inboxes worldwide per day? Per year?(Exclude those that end up in a spam folder) -Out of that number, how many emails are read worldwide per day? Per year? -How many emails are received in inboxes in the United States per day? Per year?(Exclude those that end up in a spam folder) -Out of that number, how many emails are read worldwide per day? Per year? -How many state and federal civil spam lawsuits are filed in the United States per year? -How many state and federal civil spam lawsuits are awarded in the United States per year? For questions that there does not seem to be any exact numbers on, please find a source that gives some type of estimate. You can also cite sources that help make an estimate, for example, the total number of civil cases filed per year in the United States, combined with the total number of FTC spam complaints to give an estimate of the percentage of civil cases that are spam related. You should also use Quora, Yahoo answers, and other similar sites to find answers.
