3. After entering API key click Save Changes button. Then select the MailChimp list for given options. Also configure other options like: add checkbox to comment form and registration form, customize checkbox label text, pre-check the checkbox, load custom CSS style for checkbox and more.

Should I pre-check the Mailchimp sign-up box

Well, this is a subjective decision and vary from person to person. Even if you pre-check the box, user still has the option to un-check before submitting the comment. If user does not notice the newsletter checkbox and becomes subscriber – user still has to click confirmation link in the email message sent by MailChimp (which he can reject or accept). So, pre-checking the newsletter box should not be a problem and may result in more subscribers.

    Hey there, BasicWP.

    Thanks for writing about MailChimp for WordPress. Your explanation on how to get your MailChimp API key via the new MailChimp interface is very detailed. Do you mind if I link to this blog post from MailChimp for WP’s FAQ to make things clearer for plugin users?

    Hi guys
    Seen this plugin a few times now, but this is the first review I’ve seen.
    Notice you are using it on this site.

    Not sure about the prechecked box… have to think about that.
