Use a look-up table to compare typed email address to existing/uploaded email
I need to create a dummy variable (1=yes) that populates based on whether an email address a respondent matches one they previously provided. Or some similar solution. I cannot find any documentation on how to do this. I thought it'd be something in the Survey Flow.

Yes, you can do this in the survey flow with branch logic. You'll want to use logic that checks that the answer the respondent gave matches an embedded data that holds the email address they previously provided.
If they provided it before this survey and you have it stored in your panel, you'll 'declare' the value at the beginning of your survey flow and then later check against that field.

Enter your E-mail address. We'll send you an e-mail with instructions to reset your password.

To do this, use the branch logic to find your question, select it and then select the text response:
!
Then add in 'is equal to' and put ${m://Email1} in the blank, which is the Qualtrics tag for Recipient Email
