I'm helping out a newly formed startup build a social media following, and I have a csv file of thousands of email addresses of people I need to follow. From looking at the twitter API, I see its possible to follow the accounts if I knew their usernames, but its unclear how to look them up by email. Any ideas?
This does not appear to be an option with their API, you can use either user_id or screen name with their GET users/show or GET users/lookup options.
How can I use the Twitter API to look up accounts from email addresses?
