Email Relay and Privacy
In order to reduce the amount of spam and scams circulating on Craigslist, the service has implemented a two-way email relay. When you reply to an ad, your email is sent to an anonymous email that is a random string of letters and numbers @sale.craigslist.org. On the other end, the seller receives an email from a random string of letters and numbers @reply.craigslist.org. This protects the privacy of your actual email address, as the seller never sees your actual email. It also prevents scammers and spammers from using Craigslist to harvest email addresses.
Not Total Anonymity
While your actual email address is obscured, the relay still passes the “real name” field from your email through to the recipient. So if you have your full name listed in the name field of your address, the seller will still get that information. If you prefer total anonymity, you can either change the real name field on your email account or set up an additional email account with a pseudonym in the name field for replying to Craigslist ads.
