How can I bulk upload emails from a csv file so that I can send on mass?

Could you provide some more information on what you need to do? This would help us to provide a proper suggestion.

Thank you.

I have created a template questionnaire. Now i want to send it to 150 email addresses. From the looks of it, your tool only allows a single email at a time (unless you are ok with the other participants seeing who else is participating). Ideally I just want to upload a CSV full of email addresses and then send it out rather than doing one by one. The participients must not see who else is on the email.

This is correct, we do not have an option to share form link like newsletters. You would need to use a 3rd party email service like MailChimp.
