If you have enabled the newsletter signup feature in the UserReport online survey, people who take the survey will be asked if they would like to receive your newsletter. You can export these e-mail addresses (including some demographic information) from your UserReport account.
Go to "e-mail collect" report from the report menu and wait for the e-mail list to load. Click the export dropdown and choose your preferred format. From there, it should be easy to import them to Mailchimp, Campaign Monitor or whatever software you're sending email from.
Remember to respect the user!
Please remember and respect, that the emails you collect through the survey, should only receive newsletters sent by you. We also urge you to keep in line with e-mail best practices, always providing an easy-to-follow unsubscribe link.
