For those who enjoy Yahoo email service, you can now change your signature style with a message taken directly from Twitter.
So, if you still don’t have a signature or if you want to change it with something more representative for you, the new Yahoo option allows you to integrate the most recent tweet from Twitter in your Yahoo email signature. For this, you have to enter Yahoo mail, then Settings > Accounts > Primary Yahoo and then select ‘Include your latest Tweet from Twitter’.
In case you are not proud of your tweet, you can always manually delete the message before sending the email. If it’s not too late.Source: engadget
