Good morning Master, have you tested this model? How Gmail works is very complicated. The best thing is to have your own provider for sending mass emails.

Buenos días Maestro, ¿ha probado este modelo? El funcionamiento de Gmail es muy complicado. Lo mejor es tener tu propio proveedor para el envío de correos electrónicos masivos.

Gracias, tks.
