Yahoo recently unveiled a fun new feature for email that lets you automatically embed your latest tweet below your email signature. The newest addition to Yahoo Mail is active now on the desktop—the option is not yet on mobile—for the socially inclined. 

Here’s how it works.

First, open up Yahoo Mail and click on the settings cog in the upper right corner. Now select Settings > Accounts.

Start by selecting your email account.

At the top of the window that pops up, click the account you want to add a signature to under “Email accounts.”

This is where you can add your signature and link your Twitter account in Yahoo Mail.

Now scroll down the next screen until you see the “Signature” heading.

Here, simply click the box “Append a signature to the emails you send,” and “Include your latest Tweet from Twitter.”

You must authorize Yahoo Mail to access your Twitter acount to embed your latest tweets.

Clicking that last box will bring up an OAuth window from Twitter authorizing Yahoo Mail to access your Twitter account. Once that’s done, you’ll see a confirmation that linking your email and Twitter accounts was successful. Now hit OK then Save and you’re done.

Now whenever you compose an email, your latest tweet will be embedded in your message. Fortunately, Yahoo had the good sense to include an option to delete tweets in your email compose window.

Watch out for bad language tweets auto-attached to your email.

This is important if, like me, your tweets include the occasional swear word. As you can see here, that could lead to some poorly received emails depending on the recipient.

For times like these, hover over the tweet in the compose window and you’ll see an “X” in the upper right corner. Click that to remove the tweet from individual email messages.

The swear-filled tweet will still show up next time you send a message, however. Be on your guard or clean up your act by tweeting something a little more benign in the future.

The impact on you at home: If you ask me there aren’t too many practical reasons you’d want to include recent tweets in your email messages. It may be worth it if you want people to know you have a Twitter account and make it easy for them to follow you. For most of us, however, it’s a fun little addition to spice up the look of your email.
