E-mails sent from the Survey environment contain disclaimers. The disclaimer always contains the following text:
Do you have a question or would you like to unsubscribe? Do not send an e-mail to this address, but click here. We take your privacy seriously. Click here for the privacy statement.
You can also have the entire disclaimer removed for the entire account. Take please contact email@example.com . As the disclaimer has been turned off, you must provide an unsubscribe link yourself. European legislation requires company emails to include a link to an unsubscribe page in the email. If not, email servers such as Gmail will flag the e-mail as spam.
You can also use the menu via "Survey" and "Settings" to select the comment option. By ticking the box "Allow comments via disclaimer" participants can enter feedback in the survey. The respondent then has no option anymore to provide a comment through the disclaimer in the e-mail.
