  • Your keyword is part of every disposable email address. Once you choose it, you can’t change it.
  • You can use a keyword that makes sense to you, but it can’t have spaces or symbols.
  • You can create up to three disposable addresses for free, using a different keyword for each. Want more than three? You can upgrade to Yahoo Mail Plus for AT&T.
