• Hello guys @ WooCommerce Mailchimp, I have a problem with your plugin. After the installation and the activation of you plugin in my WooCommerce site, I paste the API key in the field but it didn’t work. Everytime it says me “503 Service Unavailable”. Why this happen? Thanks in advice.

    Haven’t changed anything either. Was working a few days ago.

    Please reach out to MailChimp support to make sure they are not blocking request from your site. We have seen several issues with MailChimp aggressively blocking API traffic from customer sites. You’ll need your site’s IP address to provide them so they can whitelist the traffic.
