Qualtrics - Workflows should replace email triggers.
Please replace email triggers
Email triggers can simply stop working without warning, as I discovered around three years ago when I migrated to workflows. The email triggers option is purposely hidden in the survey options>>post survey, however please eliminate the email triggers after workflow set up processes to avoid receiving two emails.
Workflows are more powerful, and you can see when they fail on your home screen, plus you can create failure notifications.
