text: what if i have a yahoo email can i change a letter with out making an entire new email?   hi muslimsoldier4life...  i am not quite sure of what you really mean, but if you are speaking of having an email address and want to change one letter or so in to something else without having to go through the entire process of creating a new email...then the answer is simply no...  this is because the letter you want to change in your email may match an email that already exists...  also, changing a letter means changing the email address...when people send you emails after you change the letter, all these mails won't be delivered to you, but to the old account that you changed...thats why its not possible to change letters in your existing emails account...
