Let's say I wanted to respond to an ad on Craigslist, but didn't want to use my main Gmail account, which has my last name in it. Instead, I want to use a secondary account that I generally use in case of SPAM, junk email or whatever. An anonymous email account, if you will. Today I tried responding to an ad and went through the motions of typing out those coded words, but when I was prompted by an email to address the person, it automatically defaulted to my main Gmail account and didn't give me the option of chosing a different sender account (my secondary Gmail account). I went into the menu to see if it was possible, but I didn't see anything that would give me the option to change to the other Gmail account. My goal is to have access to both email accounts when sending outbound emails in situations like this, and toggle between the two whenever I need to email friends or total strangers to conduct business. Any suggestions?
