Mailchimp is forcing double optin

Hi,

I’ve succesfully integrated Mailchimp with S2Member. However I checked single optin (on Mailchimp as well as S2Member) Mailchimp sends the user a confirmation email.

What am I missing here?

Nothing. Deep in MC’s docs stay a message, that double opt-in can not be switched down, except with a custom code (trough their API).

Obviously this hack doesn’t work anymore, can anyone confirm that?

Hi,
I have found the solution by adding following filter
add_filter(‘ws_plugin__s2member_mailchimp_double_optin’, ‘__return_false’);
in to hooks.inc.php file. You will find the file in wp-content/plugins/s2member-pro/src/includes
