The form shows a success message but subscribers are not added to my list(s)?

If the form shows a success message, there is no doubt that the sign-up request succeeded. Mailchimp could have a slight delay sending the confirmation email though. Please check again in a few minutes (sometimes hours) and don’t forget to check your junk folder too.

When you have double opt-in disabled, new subscribers will be seen as imports by Mailchimp. They will not show up in your daily digest emails or statistics. We always recommend leaving double opt-in enabled.

How can I style the sign-up form?

You can use custom CSS to style the sign-up form if you do not like the themes that come with the plugin. The following selectors can be used to target the various form elements.

.mc4wp-form { ... } /* the form element */
.mc4wp-form p { ... } /* form paragraphs */
.mc4wp-form label { ... } /* labels */
.mc4wp-form input { ... } /* input fields */
.mc4wp-form input[type="checkbox"] { ... } /* checkboxes */
.mc4wp-form input[type="submit"] { ... } /* submit button */
.mc4wp-alert { ... } /* success & error messages */
.mc4wp-success { ... } /* success message */
