The Email field type marks a field exclusive to email addresses and hyperlinks it, so you will be routed to your system's default mail client to draft an email. This field type is mainly used for tracking your leads, and clients by entering their emails. 

How does it work?

1. Select Email from the list of field types.
2. Enable the option Allow Multiple Email, to type multiple email addresses in the same cell.
3. Hit Enter.

The field is now exclusive to email address. 

Enter the email address, which will turn into a clickable email id format 

Clicking on the email address will direct you to choose the appropriate application to send email.
