By default, respondents can’t approve or reject their submissions. If the options Collect email addresses and Approval Workflow are selected simultaneously, the email to approve or reject the form submission will not be sent to the respondent. Form Publisher will only send the respondent an email notification indicating that the validator approved or rejected the request.
1. Configure your settings
If you want the respondents to approve or reject their submissions, make sure Collect email addresses is not selected in the Google Form settings.
Open your settings, uncheck Collect email addresses and click Save.
2. Configure your Google Form
The only way for the respondents to approve or reject their submissions is to add an email address question manually in your form.
From your Google Form, add the question Email Address.
Select Required if the respondents must answer the question.
You can restrict the answer to the format Email address only. Click on the three dots button > Response validation.
Select Text and Email address.
3. Configure Form Publisher
From the Sharing options and notifications sidebar, add the marker <<Email Address>> and select Approval Workflow. Click Next to finish your configuration.
Your marker must match with the question title.
