Send Survey
To send a survey to mail lists, navigate to the survey edit area and on the right side, click on the tab Send Survey
You can select from all the 3 predefined mail lists to send the survey to or you can create your own custom mail lists in Utilities->Surveys->Mail Lists.
Additionally, when you click on Customers or Leads, you can even select customers that belong to a specific group or leads that belongs to a specific status.
Because the most hosting providers have a limit for sending a specific amount of emails per hour, survey emails will be sent via CRON JOB. The amount of emails to be sent per hour can be configured in Setup->Settings->Cron Job->Surveys
