All Onepagers by default collect sign ups where your traffic will be able to create a Free Onepager account and be able to view and edit a copy of your Onepager.
You can export the sign ups generated by your Onepagers so that you can upload them to any mailing service such as MailChimp, etc.
You can find the export button inside of the Signs Ups tab on any Onepager.
Here you will be able to export your sign ups to a CSV file. Each file is limited to 5,000 emails. If you have more than the limit you will see multiple download links.
The answers or inputted data will not be recorded inside of the CSV files at the moment.
