You can enable a toggle in your form settings to ensure each respondent submits your form only once. This helps prevent duplicate submissions, resulting in more accurate and reliable data.

How it works

After publishing your form, turn on the Prevent duplicate submissions toggle in your form settings. The setting is in the Access section.

Select a unique identifier field (such as IP address, email, Respondent ID or any other form field), which Tally will use to detect and prevent duplicate submissions.

Whenever Tally detects a duplicate submission attempt, the respondent will see this error page pop up, preventing them from submitting the form.

An example

You have a registration form with an email input field, and you select it as the unique identifier.
