How to stop receiving spam messages from form submitter?

Thanks. I have looked through all of the submissions and 99% are spam. It looks like somehow computers from crapy online stores have found our site and used our form to send us spam sales junk. How can we get rid of it???

Hi,

You can limit the amount of submissions you are able to receive in various different ways:

For your case I would recommend enabling "Strict Check" in the "Unique Submission" field.  This would allow for only one submission per IP address and the spammers will not be able to spam you anymore.  

Please let us know if you have any further questions and we will be happy to help.

Thank you for using JotForm!
