Can I send emails to my customers with Exotel?

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
