Email Validation
This plugin is commonly used to validate respondents' email addresses they provide in your survey or form. Respondents who entered syntactically incorrect email address or address with non-existing domain name will not be able to proceed further or submit.
Specify following parameter to apply "Email validation" plugin to your form/survey:
*Email Field - Enter reference to a question where you ask respondents for their email address. Use Qx.Ay format, where:
x - question number;
y - answer choice number.
Please note, that this plugin also works with question and answer identifiers, so you can use them instead of question and answer numbers in plugin parameters.
