Fallido (Failed) means none of the emails could be sent. It is different from Alerta (some went out and others failed) and from Bloqueado (Blocked: the send was stopped to protect your account). Labels are shown as they appear in the Spanish version of the console.
AFRUS stopped the send because there were too many bounces or complaints. It can't be sent again from the screen: contact support.
The account gets blocked for having too many bounces and needs credits assigned. To solve it, write to the support email.
