Sisense Emailing mechanism is based on Mandrills' services, Mandrill is an email infrastructure service. Having your own Mandrill account allows you to monitor the emailing status, how many emails have been sent, whether the emails have delivered or opened. A Mandrill account will also allow you to change users emailing display when receiving an email. Right now users will be displayed that the email has been sent via mandrill. This can be customized within your mandrill account, learn more of this within the following link Mandrill settings.
This post will describe how you can set up your own Mandrill account with your Sisense account.
Mandrill's Emailing settings can be found in the deafult.yaml file under C:\Program Files\Sisense\PrismWeb\vnext\config\default.yaml
Within the default.yaml file, please find the Email section and enter the "senderEmail" and "senderName" you want to use instead of "sisense-admin", and enter your own Mandrill key under "api_key" (provided by Mandrill)
Note: This does not support re-configuring to a non-Mandrill service.
After reconfiguring please restart your IIS and the service called "Sisense.Repository".
Please note that this setting overrides the default.yaml component, when upgrading or re-installing Sisense you will need to re-configure this.
