Hello @four77,

To the best of my understanding, when a survey is sent anonymously, participants are unable to revise their responses as the system doesn't identify them. Conversely, if personalized links were used, respondents can edit their answers by receiving a Retake Survey link, which pre-fills the survey with their initial responses.
Let me know if this helps.

FWIW, Qualtrics users can generate a Retake Link for an response submitted via an anonymous link. But the trick will be whether or not you have sufficient information to identify the response to reopen.

Thanks! @MatthewM  I am curious to try that out -- does it happen to pre-populate with the original responses? (Assuming so, just curious!)

It has for me. There might be some unknown exceptions, though, like perhaps if you’re using CAPTCHA.
