Preguntas frecuentes

Más documentación

Se puede encontrar documentación más detallada en el Base de conocimiento de Mailchimp for WordPress.

¿Cómo mostrar un formulario en publicaciones o páginas?

Use el atajo [mc4wp_form].

¿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.

¿Dónde encuentro mi clave API para conectarme a Mailchimp?

Puede encontrar su clave API aquí

¿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?"]

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

Si el formulario muestra un mensaje de éxito, no hay duda de que la solicitud de registro se realizó correctamente. Sin embargo, Mailchimp podría tener un ligero retraso al enviar el correo electrónico de confirmación, solo sea paciente y asegúrese de verificar su carpeta de SPAM.

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

Recibo un “error HTTP” cuando intento conectarme a Mailchimp

Si obtiene un Error HTTP después de ingresar su clave API, comuníquese con su servidor web y pregúnteles si tienen PHP CURL instalado y actualizado a la última versión (7.58.x). Asegúrese de que las solicitudes para https://api.mailchimp.com/ también estén permitidas.

¿Cómo muestro un formulario de registro en una ventana emergente?

Recomendamos el plugin emergente Boxzilla para esto. Puede usar el shortcode del formulario en su cuadro emergente para mostrar un formulario de registro.

Mi pregunta no está en la lista.
