We have evolved from phone calls to text messages and countless emojis. And now, thanks to the popularization of GIFs — quick, bite-sized animated graphics that play over and over again in a loop with no sound — we barely need to use any words at all to communicate how we are feeling and what we are thinking. And this transformation is not isolated to our personal lives — brands and marketers are incorporating this type of visual content into their content strategy and campaigns. Why? Because they drive engagement and clickthrough, in both email and social media.
