I'm sorry, but there is no single web address or official list of email addresses for members of the U.S. House of Representatives. The best way to find contact information for a specific representative is to visit their official website, which can be found by searching their name on the House of Representatives website: https://www.house.gov/. Most representatives have a "Contact" or "Constituent Services" page on their website where you can find their email address and other ways to contact them.
