How to verify whether an email already exists in Contact Form 7 submissions?
We need to install two plugins. Install Contact Form 7 database add-on and duplicate control add-on (Contact Form 7 prevents duplicate submissions)
Demo: https://woo.ciphercoin.com/unique/
Contact Form 7 prevents duplicate emails on the demo page. I added an email input field as a unique field.We will receive an error message, such as “email already exists,” if we resubmit the same email.
Like that, this plugin is helping to limit submissions.
