I need to be able to see the system e-mails I send from Zoho Invoice and I understand  that if I had chosen to use mail programmes such as GMail or Outlook  then I could have integrated and had this feature.

However, I chose to use Zoho Mail and and now understand that I am disadvantaged because as there is no integration available like with the non Zoho programmes? 

This is something that has been asked for for over 2 years in Zoho invoice forum for over two years and still nothing. 

Zoho this is not a good look making other providers products superior to your own?  It lets down your faithful users. 

Can this integration be developed ?
