Are email addresses visible to anyone?
A requester's professional email address is partially visible on the survey page while the survey is still open (the @domain.com part). However, only invited respondents with the link to the survey would see it, and we take various technical measures to prevent Search and Bots from scraping our site and picking up the full address.
In detail - who sees what email address
Respondents never provide an email at all to respond. If they choose, as part of their survey response, they can offer a contact email if they would like to participate in the Trust Circle feature of the survey they are participating in. To learn more about Trust circles, please read this article. You can respond to your survey in full and not opt into a Trust Circle.
Requesters, on the other hand, must show their professional email address along with their LinkedIn information on all their in-flight surveys. There is no opt-out for this: Requesters must appear in full verified transparency to respondents they are approaching, and a professional email address is part of those trust signals.
However, as soon as a Survey closes and enters its archival mode, we no longer show any Requester personal information. This data was displayed only to contextualize the original request for participation; once that purpose is fulfilled, it’s automatically withdrawn from public view.
If you want to know more about we prevent discoverability, scraping and other automated content harvesting, you can read more about the measures we take here (Tl;dr: we use expose a partially anonymized requester professional email address and do some kung-fu to only show your full email if a human clicks a button and we can verify they are not a bot, surveys and their reports aren't crawlable by SEO or our sitemap, and we have various bot-fighting tools in place)
Internally, we store Requester login emails (potentially different from their professional email) to manage authentication, verification, and support. These are, of course, never exposed on public pages
