Prohibit duplicate forms with the same email

Hey Webflow,

I recently launched a website where I got a much higher response than anticipated. However, some of the email signups were duplicates. Since Webflow limits the number of form submits by billing plan, I was wondering if there was a simple way to prohibit the same email being submitted in a form. For example, a simple newsletter signup form. If they did try to sign up, I would like to display the form error message. This could lengthen the amount of time it takes me to hit my form submit limit. I could go through and delete duplicates, but when we are talking about hundreds or thousands of submits, that becomes tedious.

If you have any ideas, please let me know.

Thanks!

Use a professional newsletter service like mailchimp.com. That will prevent duplicate emails.
