Thank someone for following you on Twitter and let them know how you did it!
Create a filter in Gmail so when you get an e-mail about a new follower on twitter, you automatically send a tweet thanking (and tagging) the new follower and and letting them know via url to this receipe as to how you did it!. Your Gmail filter will be a search for "is now following you on Twitter!" in the subject line. This filter is to apply the Label 'TwitterFollow'. Then IFTTT tweets "Thank you for the Follow! (Person Name (@twitterhandle) is now following you on Twitter!) via @IFTTT #recipe65060 https://ifttt.com/Applets/65060".
