How to Pass Convertkit Subscriber’s Email Address as a Query String Parameter

Recently I was trying to figure out a way to send a Typeform Survey to my Convertkit (aff link) email subscribers that didn't require them to enter their email address once they click over to the Typeform Survey.

I wanted to pass this data using a query string parameter.

This is ideal for UX purposes but it's also for functional purposes. You see, I want to store the Typeform responses on the subscribers Convertkit profile using the same email address they signed up with originally.
