If the survey invitation has already been fully sent, it cannot be recalled. However, if the distribution is still in progress (which you can verify in the Download Center), you can cancel it before it reaches 100%.
To cancel: Go to Analytics > Manage Data > Download Center and click the X button next to the ongoing email distribution.

Note: Cancelling midway will stop only the undelivered emails. Emails already sent won’t be recalled.
Alternative:
If the entire batch has been sent and you don"t want recipients to take the survey, you can close the survey, create a copy, and continue working on the copy. Once ready, you can send the invitation for the new (copied) version.
