Mailchimp integration duplicate emails

Hello
When s2member send information to MC about new user registration MC adds this user to free list and to list what i need.

the logs i have:

'function' => 'process_list_server_removals',
  'func_get_args' => 
  array (
    0 => 'subscriber',
...
 4 => 'sadensmol@icloud.com',
...
  'api_removal_method' => 'listUnsubscribe',
  'list_id' => '3544ccb97c',


 'errorMessage' => 'sadensmol@icloud.com is not subscribed to list Free Version',

...

  'function' => 'process_list_servers',
  'func_get_args' => 
  array (
    0 => 's2member_level8',
...
    4 => 'sadensmol@icloud.com',
...
  'api_method' => 'listSubscribe',
  'list' => 'd9bfac6da0',
  'list_id' => 'd9bfac6da0',

But after that i have registered in group d9bfac6da0 ( that i need ) and also in group 3544ccb97c. I received email only from group d9bfac6da0.

I dont need to add user into the free list along with adding it to needed list.
I think listUnsubscribe works incorrectly!

Please help me and advice.

From what it looks like, it seems the user isn’t even subscribed to that mailing list correctly, the logs say so:

[...]

'api_removal_method' => 'listUnsubscribe',
'list_id' => '3544ccb97c',
'errorMessage' => 'sadensmol@icloud.com is not subscribed to list Free Version',

[...]

Hi, Eduan.
Thank you for the answer.

Initially user isn’t subscribed to any list.
They when new user has registered s2member send those 2 requests to MC
one request to unsubscribe from free list ( but user wasn’t registered before! ) – why do we need this request?
and 2nd request – for subscribe to correct list ( related to user level)

After that i get email from MC about new subscription to correct list and Welcome email from free group!

I asked this question MC support team they said that it’s s2member problem.

s2member version is
Version: 120608

My client has bought pro version so i could move this topic to customer forum.
Can you help me to figure out what wrong here?

Hello Denis,

OK, so first things first, UPDATE s2Member. It is currently in the version that was released in June 2012. The most current version was released the 20th of February of 2013.

Also make sure to update WordPress, you would want to update s2Member first though. ;)

After you update s2Member and WordPress, if the problems continue then please try these common trouble shooting tips: Knowledge Base » Common Troubleshooting Tips

While you’re at it, update all your plugins and maybe even your theme. ;)
