To be able to use the plugin, you have to get API credentials from Mailchimp. You can find them in the <a href="https://us1.admin.mailchimp.com/account/api/" rel="nofollow ugc">API keys section</a> of your Mailchimp account. If you already use the plugin “Mailchimp” or “Mailchimp for WooCommerce”, the API key from these will automatically be used.
The plugin allows you to show all campaigns from the connected Mailchimp account. You can show up to 100 campaigns (this is a hard limit of the Mailchimp marketing API). For each campaign, you can either show the “Title” or the “Subject”. You can also show the author/sender as well as the sending date (and time).
This is not an official Mailchimp plugin. Mailchimp® is <a href="https://mailchimp.com/legal/copyright/" rel="nofollow ugc">a registered trademark</a> of The Rocket Science Group.
