For the times when words aren't enough, Gmail will now offer emoji reactions to emails.

After rumors that Google was working on the reactions, the company has confirmed the addition of emoji reactions to its Gmail service, rolling out first with Android users and eventually moving to other devices. The feature is similar to reactions available on Apple's iMessage.

The reactions will not work with emails opened in another provider, like Microsoft Outlook or Apple Mail.

Emoji reactions cannot be sent from work or school accounts, to messages in a group email or messages with more than 20 recipients. They also cannot be sent if you are in BCC, if the sender has a custom reply-to address or if you've already sent more than 20 reactions to the same message.

And if you want to remove an emoji reaction you've already sent, Gmail has an undo feature built in. Depending on the "undo settings" in your Gmail, which can only be changed on your computer, you will have from 5 up to 30 seconds to remove an emoji reaction after you add it, according to Google. To remove the emoji reaction, tap "undo."
