Help with duplicate form submissions?

Hello,

I've been encountering an issue where some forms are being sent in duplicate. Usually the duplicates are sent hours or even days after the original was submitted. In some cases multiple duplicates (up to 4) have been received. We've contacted some of the customers who we received duplicates from and in all cases they claim they have not initiated the duplicate form. Any idea what this is caused by? Would you recommend adjusting unique submissions settings? Would doing so prevent carbon copies from coming in or would it target all future submissions by the customer? Thanks!

Hi Adam,

Thank you for reaching out and my apologies for the inconvenience.

Yes, if you have the Unique Submission enabled on your form and it is set to Check cookies only, users can only submit once using the browser he used to submit his Form.

However, if he uses another web browser, he can submit again.

When your user resets the browser's cookies, then they can submit once again.

I would suggest the Check cookies and IP in the unique submission.

However, when using the IP address, this doesn't limit to just a day, but with the IP address, he has used.

2. You may also use Unique Question method to limit the user from submitting the Form.

You may target the email address or the full name of the user so that they cannot use the form.

Hope this information helps.

Please let us know if you have further questions.

Thank you.

Update:

Duplicate submissions issue is now fixed. We added some preventive measures to help deter unwanted resubmissions of the previous entry. This should not happen again.

Thank you for your patience.
