New Subscription doesn’nt integrate with mailchimp

Hello,
I’m using most of the popup type. I didn’t get any problem.
Today, I got a problem subscription list. I will let you know in detail,
I got subscriptions with subscribing popup. Popup builder shows the real subscriber count. On the other hand, my mailchimp account doesn’t shows less subscriber. I integrate mailchimp with my woocommerce, integrate popup builder also with Api keys.
What do you think?
