How to Add CAPTCHA to a Contact Form


Staying in touch with your customers is an important part of any marketing plan. The contact database is made up of individual contacts that represent an individual person or business and contains specific contact information. This information includes each contact's name, address, city, state, and phone number. With Zift123, you can target specific segments of your existing contacts to create contact lists. Once your list is built, you can deliver content using campaign activities such as email and print media. Created lists are available for reuse and may be used as the basis for new lists.

Often a Contact Form is used to gather consistent data from contacts reached through your marketing activities. Using a CAPTCHA on a form is a way to tell humans and machines apart. Using CAPTCHA improves the data gathered from the contact form.
