Got no and still getting no support for this plugin. It's useless if you have a bug and get no support.

Love this plugin but we're driving traffic to a busy site and capturing data to Mailchimp using this plugin and it has completely halted our efforts. I'll edit my review when it's fixed.

Used this to collect newsletter subscribers for 2 years or so. It seemed to work fine when tested, but it turns out it didn't work with subscribers using certain browser settings, but didn't spit out any kind of error or give any indication. Always just gave a success message. MailChimp has a problem with browsers auto-filling hidden fields (Google "mailchimp too many signup attempts" for more info) and was rejecting a lot of subscribers. There's a workaround for this, but you have to know it's happening! I'm now using an embedded form from MailChimp's form builder (and the workaround mentioned above) instead of this extension.

I really wanted this plugin to work, but the custom fields feature does not function properly. Beware! If you use anything other than the default MailChimp merge fields, you will probably have trouble too. I contacted the developer twice (once on 10/02/2018 and again on 10/15/2018) using his preferred contact method. Now, 20 days after my original message, I still have not received any response. Seeing as how the plugin has not been updated in the past 8 months and the author is missing in action, I suspect that this plugin has been abandoned.
