My company currently uses Slido during webinars to ask survey questions and show entertaining dynamically-updating results as answers come in.
It's working well except for this drawback:
Our surveys always feature this question: "What email address did you use when registering for this webinar?" People too often mistype their email address or provide one that wasn't actually the email address that they used when registering.
So then we're unable to match their responses to other pieces of data in other systems of ours.
We'd prefer to send an email (from our own custom email system) to each webinar attendee at the scheduled start time of the webinar, and each email message would contain a unique personalized link to the specific survey for that session, and within the link we would include this attendee's (confirmed) email address. E.g. the link could be https://app.sli.do/event/k3dJ85BvgGQUk/live/questions?email=john@example.com.
We would want the survey system to then invisibly record the email address of that respondent (in a way that does NOT let the respondent change or delete the email address), and then the respondent's answers to the (visible) questions during that session would all be associated with that email address.
In other words, we're looking for a tool that allows us to ask survey questions in an entertaining way (dynamically instantly updating charts of results while people answer the questions) that also allows us to easily authenticate respondents via URL.
Alternatively, it would also be acceptable if the unique identifier that we pass to the survey system is something other than an email address. For example, our custom app that is responsible for sending the emails could pass a user ID or a GUID or whatever. It will be a success as long as we can tie responses back to the confirmed email address that we know for a webinar attendee.
