Abstract: Techniques for providing email reactions via embedded tokens are disclosed. One example technique includes outputting an original email with an emoji interface that allows selection of emojis at a first computing device. Then, upon detecting selection of one of the emojis, the first computing device can automatically generate a reply email without manual composition. The reply email has data of an email reaction token and the selected one of the multiple emojis. Upon receiving the reply email, a second computing device can determine whether the reply email includes any email reaction token. In response to determining that the received reply email includes the email reaction token, the second computing device can render and surface the one of the multiple emojis on the original email without appending the reply email to an email thread corresponding to the original email.
