Restrict what emails your visitors can submit

Email submission is an important step towards qualifying and engaging with a site visitor. It becomes important for B2B businesses to understand the visitor’s identity to serve them better.

Benefits of email validation:

  • Improve the number of work emails submitted via chat.
  • Improve SDR productivity through time saved in outreach to spam or personal email submissions.
  • Build a holistic picture of the account you are engaging with and take advantage of your ABM enrichment efforts.

Pre-requisites: To configure a conversation step in the conversation flow, you will need to have permissions to ‘Edit’ conversations in the Conversations tab.

How does email validation work?

Insent’s email validation algorithm checks the email domain submitted by a site visitor on a chatbot form. It ensures that the email submitted is not associated with known personal email service providers or spam mail services. Email validation helps ensure that the leads captured are more interested in engaging with your company and understanding your offerings.
