WPForms

WPForms is a drag-and-drop form builder that stays inside WordPress, so no coding required. The plugin includes add-ons that sync your form submissions directly to Mailchimp, Constant Contact, and other email providers. You can collect leads, confirmations, or any data without writing integration code.

This suits WordPress beginners and small businesses that need basic form collection tied to their email list. It's not a marketing platform itself, but a bridge between your WordPress site and the email tools you already use.
