Registros SPF, DKIM, DMARC. Qué son, y por qué son ESENCIALES para tu correo.

Los registros SPF, DKIM y DMARC son unos mecanismos que ayudan a identificar que un correo viene del servidor real. Es decir ayudan a que tu correo no vaya a la carpeta de spam de tus clientes y contactos, y a que la gente no envíe correo en tu nombre (o en nombre de tu dominio).

Hoy en día, estos mecanismos son esenciales, tanto es así que Google y Yahoo los han hecho obligatorios para envíos masivos.

Te explicamos qué son estos registros de DNS. Como resumen:

• SPF: lista las direcciones IP o dominios que pueden enviar correos para ese dominio.
• DKIM: es una firma electrónica del correo que asegura que el correo no haya sido modificado desde el origen.
• DMARC: permite establecer las políticas que aplicar si los mecanismos anteriores dan el correo como falso. Puedes poner que se vaya a spam, se rechace o se entregue.
