Preguntas frecuentes

Where can I find my Mailchimp API key?

You can find your Mailchimp API key here

¿Cómo mostrar un formulario en publicaciones o páginas?

Use the [mc4wp_form] shortcode or the Gutenberg block.

¿Cómo mostrar un formulario en áreas de widgets como la barra lateral o el pie de página?

Vaya a Apariencia > Widgets y use el widget Mailchimp for WP Form que viene con el complemento.

¿Cómo agregar una casilla de registro a mi formulario Contact Form 7?

Use el siguiente código corto en su formulario CF7 para mostrar una casilla de verificación de suscripción al boletín.

[mc4wp_checkbox "Subscribe to our newsletter?"]

Our knowledge base has more information on connecting Contact Form 7 and Mailchimp.

El formulario muestra un mensaje de éxito pero los suscriptores no se agregan a mis listas.

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.

Cuando tiene la opción de doble inhabilitación desactivada, Mailchimp verá a los nuevos suscriptores como importaciones. No aparecerán en sus correos electrónicos o estadísticas de resumen diario. Siempre recomendamos dejar habilitada la opción de doble registro.

¿Cómo puedo diseñar el formulario de registro?

Puede usar CSS personalizado para diseñar el formulario de registro si no le gustan los temas que vienen con el complemento. Los siguientes selectores se pueden usar para apuntar a los diversos elementos del formulario.

.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 */
.mc4wp-error { ... } /* error messages */

Puede agregar su CSS personalizado a su hoja de estilo de tema o (más fácil) utilizando un complemento como Simple Custom CSS

Connected my list in a few minutes, forms match my site’s styling without extra tweaking, and double opt-in works as expected. No complaints so far.

We have been using MC4WP for almost a year now, and I am so pleased how it has been working for us. It was easy to integrate and set up. No issues, so I highly recommend you use it for your site.

Clean, stable and updated regularly

I’ve been using this for a long time to add subscribers to Mailchimp both on a form and in the Woocommerce checkout. I recently encountered a problem experimenting with the Woocommerce block-based checkout and M4CWP support were great. Highly recommended plugin.

Tried Mailchimp for WordPress for my forms. It connects fine and does the basic job. But the setup felt a bit confusing at times. Works ok overall, but could be simpler and smoother.
