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 configuring your Thank You Tweet you can select what day of the week you would like your tweet scheduled as well as which Twitter profiles you would like to have this feature.
When selecting users to thank we take two factors into consideration: 1) have they retweeted at least one piece of content this week and 2) how many followers do they have. This means that we are always thanking those users who have the largest reach and are retweeting your content. Note: they do not have to be your follower.
