The Salesforce Web to Lead functions  are a great way to leverage form pages on your company's website, to capture contact and profile information from users and automatically generate new leads in Salesforce, enabling you to respond in real-time to customer requests.

FormCheck prevents Spam, fake or duplicate web-to-lead entries by eliminating or isolating invalid names and e-mails and Spam content into quarantine queues. FormCheck also enhances your web-security by hiding the OID and by ensuring the data is actually coming from your website

FormCheck validates the name and email data in your Web-To-Lead forms and sets an overall score and assigns duplicates to a separate queue. The overall validation score is an average of several scoring tests, including checking e-mail and name syntax, valid MX record, and name verification against our Good Names^TM database that provides for one billion valid name combinations.
