Core Feature Capabilities

Hulk Contact Form Builder: Comprehensive, Customizable, and Advanced

Hulk Contact Form Builder’s feature set is designed for merchants who want more than just a simple contact form. Its advanced conditional logic allows forms to adapt in real-time based on user input, making surveys and lead qualification more dynamic and personalized. The booking element transforms a form into an appointment scheduler, ideal for service-based stores or consultations.

With the ability to connect custom email domains, merchants ensure their communication is branded and professional. Creating customer accounts directly through forms streamlines onboarding, while custom fields and custom styles give complete control over form appearance and data capture. The drag and drop design interface means anyone can build complex forms without coding, and Google reCaptcha integration protects against spam.

Email notifications and the ability to customize auto-response messages ensure both merchants and customers are promptly informed. Exporting submissions, integrating Facebook Pixel, and tracking UTM parameters provide valuable data for marketing and analytics. Hulk Contact Form Builder supports file uploads (with a generous 100 MB limit), multi-page forms for longer surveys, and pop-up forms to increase visibility.

Other highlights include form scheduling, restricting submissions to logged-in users for member-only content, deep Shopify theme integration, Slack and Zapier integrations for workflow automation, and unlimited forms even on higher tiers. Heavy storage allowance means merchants don’t have to worry about hitting limits as their business grows.

ECF: Contact Form Builder: The Essentials for Simple Contact Forms

ECF: Contact Form Builder focuses on delivering the essential tools for easy contact forms. It supports multiple field types, file uploads (up to 5 MB), and basic anti-spam with Google reCAPTCHA. Merchants can export form submissions, customize the receiver’s email template, and set up thank-you emails for users. The app supports integration with MailChimp, Klaviyo, and Google Sheets, which helps merchants manage leads and automate responses.

The advanced plan adds features like webhooks for sending data to third-party URLs and custom JavaScript functions before and after submission, giving more technical users the ability to extend functionality. However, the core set of features is best suited to merchants with straightforward needs who don’t require advanced logic, booking, or deep customization.

In summary, Hulk Contact Form Builder does everything ECF: Contact Form Builder offers—and much more—making it a strong choice for merchants who want both foundational and advanced form capabilities.

Pricing and Value

Hulk Contact Form Builder offers a truly free entry point with its Basic Plan, which includes one form, 50 submissions per month, unlimited storage for file uploads, export capabilities, email notifications, and style customization. This is ideal for new or small merchants who want immediate value without upfront costs.

The Pro Plan, at $9.90 per month, unlocks unlimited forms and submissions, UTM tracking, pop-up forms, Facebook Pixel integration, custom sending domains, form scheduling, and advanced response customization. For growing businesses, this tier provides advanced marketing and workflow tools at a competitive price.

The Pro+ Plan ($24.90/month) is designed for stores with high-volume or advanced requirements. It adds multi-page forms, Slack and Zapier integrations, increased file upload limits, submission restrictions, booking elements, and advanced conditional logic. Large or complex businesses benefit from automation and flexibility at this tier.

ECF: Contact Form Builder starts at $4.99 per month for its Basic plan, which includes a 1,000/month submission limit, file uploads up to 5 MB, and integration with MailChimp/Klaviyo. The Premium plan ($9.99/month) offers unlimited form submissions and export capabilities, while the Advanced plan ($12.99/month) brings custom JS, webhooks, and Google Sheets integration.

While ECF: Contact Form Builder has a slightly lower entry price, Hulk Contact Form Builder’s free plan and advanced features at similar or only slightly higher price points deliver more long-term value, especially as merchant needs grow.

Setup and Technical Fit

Hulk Contact Form Builder is Built for Shopify, offering the highest level of compatibility and reliability with Shopify’s platform. This ensures smooth integration with Shopify themes and admin, reducing setup time and minimizing conflicts. Deep integration with Shopify Flow and Shopify Admin means that merchants can automate complex workflows directly from their forms.

The app supports 20 languages, making it ideal for global merchants or those expanding to new markets. Integrations with Google Sheets, Klaviyo, MailChimp, Slack, Stripe, PayPal, Zapier, and ZeroBounce allow for powerful automation, lead enrichment, and seamless data transfer between platforms.

Bulk and automation features—such as unlimited forms, advanced conditional logic, heavy storage allowance, and the ability to restrict submissions to logged-in users—make Hulk Contact Form Builder suitable for both small and large merchants. Whether you need a simple contact form or a multi-step survey with sophisticated logic, the app adapts to your workflow.

In comparison, ECF: Contact Form Builder is not Built for Shopify and only supports English. Its integrations cover core marketing tools and Google Sheets, with advanced features like webhooks available on the top tier. For merchants with simple needs or those focused solely on English-speaking markets, setup is straightforward, but those requiring broader language support or Shopify-native integration may find Hulk Contact Form Builder a better fit.

Trust Signals

Trust matters when choosing an app to handle customer communication. Hulk Contact Form Builder has been on the Shopify App Store since 2017, earning 1,857 reviews and a 4.9-star rating. This depth of social proof signals reliability, active development, and long-term merchant satisfaction.

ECF: Contact Form Builder, launched in 2020, has accumulated 40 reviews with the same 4.9-star rating. While its rating is strong, the lower review count and shorter time on the market mean there is less historical data for merchants to assess. For those prioritizing a proven track record, Hulk Contact Form Builder stands out as the safer long-term bet.
