Squarespace offers a built-in web form tool called form blocks that allow website owners to create forms directly within their admin panel, without having to use third-party tools. Form blocks provide several benefits, including the ability to match the look and feel of the site, and can be easily customized to fit specific needs. The forms can be used for various purposes, such as creating a Contact Us page, newsletter signup forms, or specialized forms for businesses like real estate companies or catering services. Squarespace also offers integration with other tools like Google Drive, Mailchimp, and Zapier, which enable the transfer of data to other apps and automate workflows. To use form blocks effectively, website owners should think through their process before creating a form, ask appropriate questions, install reCAPTCHA challenges to curb spam, and consider enabling file uploads or running giveaways to enhance user engagement.
