Integrate Zoho Survey with Zoho Recruit

Integrate Zoho Survey with Zoho Recruit

Hi Zoho, 

I have a couple questions about the integration of the Survey and Recruit:

  1. Can the survey be sent via SMS?
  2. Can the candidate profile in Recruit update with the existing surveys already completed prior to this new integration, using the email address as an identifier?
  3. Is the only method of recording a completed survey in zoho recruit done when it is sent via email?
SMS is the main form of communication with candidates especially if the survey is a requirement, using email alone via Zoho does not give me confidence considering the high spam rate when sent from Zoho. 

Thanks,
