Thank you for reaching out to the Community. That is a great question! From your screen shot, it appears you are using our original editor. For adding emojis, you will want to use our new 3GE editor that is available in your account.
You can access the 3GE editor by following these steps: click Campaigns at the top left of your account, and select the Create button on the right. You will then see a pop up of choices appear, and select Email at the top. This will take you to the 3GE templates. Click here for getting started using our 3GE editor.
In the meantime, if you have any further questions please feel free to reach out to us here. We are always happy to assist you in any way we can!
