I add some fields to a form, but they don’t appear on MailChimp / MailerLite tab

Save form settings (click “Save” button) to refresh form element list.

I update MailerLite / MailChimp lists / fields, but old one are shown on form settings screen

Lists and fields are cached by the plugin to decrease number of requests to 3rd party services and increase performance, new data will be loaded automatically when cached data are expired.

You can also request new data manually, for this click by “↺” icon near drop-down with lists and/or “Reload fields” button to update custom fields.

I need integration with a service which is not supported by the plugin. Could you help?

PRO version of the plugin supports integration with Zapier service. Zapier can work with 500+ services.

You can also hire us and we will implement a custom solution for integration “Contact Form 7” or other WordPress plugin with the service of your choice.

This was just what I was looking for. Works perfectly and no problem with speed.

The plugin works with one of my site but does not with the other. I used the same API key for both, but one of the site failed to “check the API”. Any ways to fix this?
