No, we are not a bulk mailer or a mass mailer service. We ourselves use Amazon's SES and have been very happy with their product. 


Exotel uses email as a mechanism to notify you, and your co-workers about the events that happen in your phone system. Some events that you can configure Exotel to notify you:


  • Missed call
  • Unattended call
  • Outbound call
  • Customer voicemail
  • Call assignment from co-worker to you
  • Report download availability etc.  
  • When an agent switches on/off
For more details on what call notifications are, Please read "What notifications do I get?".

As you can see, Exotel can intimate you & your colleagues about calls & SMS-related events. But, if you want to send emails to your customers, then you have to choose a mass mailer service. And these days, there are many email marketing services.
