Mailchimp will officially end all automatic double-optin forms on October 31, 2017. Your forms on your site will not change.
This WILL affect all incentives that you send automatically.
BEFORE: a sign-up would automatically receive a ‘please confirm your address’ and the incentive was contained therein.
NOW: by default there will be no extra emails
After October 31, your incentives will not send via the thank you emails.
Fix your Opt-ins and Incentives
The forms and sign-ups on your site will still work. However any incentives will STOP unless you select your preferences for double opt-in.
To set preferences go to: Lists > Opt-in Stats
Select the lists that should receive the thank you email. And click “Save”.
That’s it! Leave your questions in the comments!
