Burberry Tweets Thank You GIFs to Fans

In honor of hitting 1 million Twitter followers, luxury brand Burberry sent approximately 3,000 thank you GIFs to fans last Monday. The thank you e-cards were personalized with followers' names and were tweeted at them directly. While this certainl seems like a nice sentiment, and given that Friday was the GIF's 25th Birthday, I wanted to determine what impact these tweets had.
