Thank You Tweet lets you thank Twitter users who have retweeted your content. Once enabled, the tweet will send automatically each week. Since the users we thank are based on your account, the tweet will be different each week.
When selecting users to thank, we take two factors into consideration: 1) they have retweeted at least one piece of content from you this week and 2) how many followers they themselves have. This means that we are always thanking those users who have the largest reach and are retweeting your content. They don’t even have to be your follower!
