    Contratamos hace unos días un plan con ustedes. Pero no puedo cambiar el e-mail de contacto con el que me inscribí, que es el mío y debo enviar como remitente el de contacto de la empresa. ¿Cómo lo puedo hacer? es urgente, si me pueden ayudar.

      Hola Sandra, ¿cómo estás? En realidad la cuenta la puedes crear con cualquier Email porque no influye en el remitente. En el momento de crear una Campaña puedes elegir el Email de remitente que desees mostrar y también te damos la opción de colocar uno distinto de respuesta. De igual forma te paso una captura explicando mejor a lo que me refiero 🙂 http://screencast.com/t/FRKHdvt4Xl . Cualquier duda adicional puedes escribirnos a [email protected]. Saludos, Julieta de Doppler.
