 * Hi,
 * I need to integrate the Hustle popup to my MailChimp account so new signups feed
   into my Email list on Mailchimp
 * I added my API key and configured the list but the email addresses collected 
   are not feeding into Mailchimp automatically. There is an error picked up in 
   the Email List part of Hustle, but unsure how to fix this.

 * Thank you.

 * Hello [@robravenswood](https://wordpress.org/support/users/robravenswood/)
 * I trust you’re doing well!
 * Is your list have double opt-in enabled? If yes, a user has not subscribed though
   the email that Mailchimp sends.
 * If double-opt-in is enabled, please try changing your list to single opt-in. 
   Please see the instructions here:
    [https://mailchimp.com/help/single-opt-in-vs-double-opt-in/](https://mailchimp.com/help/single-opt-in-vs-double-opt-in/)
 * Please advise,
 * Kind regards,
    Nastia
