Introduction

GOROMBO is a software development company that specializes in creating custom apps, software, and APIs designed to integrate seamlessly with digital storefronts and point-of-sale (POS) systems. Their solutions streamline business operations and improve customer interactions, helping businesses manage everything from e-commerce to in-person sales efficiently.

One of Gorombo’s latest products, Form2Mail, offers a powerful tool for static websites that need to handle dynamic form submissions securely. As static websites grow in popularity for their speed, simplicity, and security, they often face a significant limitation: static sites don’t support backend functionalities like handling form submissions. Many businesses turn to cloud-based solutions such as Google Forms or Formspree for this purpose, but these services come with notable drawbacks—subscription fees, limited customization, and potential security risks due to external data handling.

Form2Mail addresses these challenges by offering a self-hosted, flexible API that gives developers full control over form submissions on static websites. Built with FastAPI and SMTP, Form2Mail processes form data directly on your server, ensuring maximum security without ongoing costs or limitations. It’s especially suited for developers seeking to maintain control over their data while eliminating reliance on third-party servers.

In this article, we will explore why self-hosted form submission APIs like Form2Mail are essential for static websites, and how it stacks up against cloud-based alternatives like Formspree and Google Forms.

Why Static Sites Need Custom Form APIs

Static sites are fast and secure because they don’t rely on server-side code. However, this also means that functions like processing contact forms are missing, requiring the integration of external services to manage form data and send email notifications. Popular services like Formspree offer easy setup but operate on a subscription basis, charging more as your usage grows.

Additionally, many developers have concerns about data security when using third-party services, as form data is handled on external servers. A self-hosted solution like Form2Mail gives developers more control over their data, costs, and customization options.

Why Self-Hosted Forms Outperform Google Forms in Security and SEO

In the realm of digital interactions, web forms play a critical role—but not all form services are created equal. Public platforms, such as Google Forms, offer convenience but come with inherent risks. Hackers exploit these services to deceive users and steal personal information. Self-hosted forms, like Form2Mail, offer a more secure solution, empowering businesses with data control and reducing phishing risks.


Real-World Phishing Threats: Risks of Using Public Forms

Cybercriminals exploit public form platforms by embedding malicious forms into emails. In one campaign, attackers tricked users into submitting Office 365 credentials via a compromised Google Form. Another example involved an AutoIT script stealing system information, sending it to a hidden Google Forms endpoint for further use.

These incidents highlight the danger of relying on public platforms that attackers can manipulate to bypass security. Since users trust familiar platforms like Google, they are often more vulnerable to these phishing tactics.

Introducing Form2Mail: The Best Self-Hosted Form API

Form2Mail is a custom-built, self-hosted solution using FastAPI and SMTP to handle form submissions securely and efficiently. It’s designed for developers who want more control over form data, avoid subscription fees, and need a flexible solution for handling forms across multiple projects.

Key Features of Form2Mail:

  • Self-Hosting: You manage your own server and SMTP configuration, giving you full control over where and how form data is processed.
  • FastAPI for Speed: Built with FastAPI, Form2Mail processes form submissions quickly and efficiently, even for high-traffic sites.
  • SMTP Email Delivery: Form submissions are emailed via SMTP with customizable sender and recipient details, making it adaptable for any project.
  • API Key Authentication: Ensures only authorized requests are processed, securing your forms against spam and unauthorized submissions.
  • Cost-Effective: Form2Mail eliminates the recurring fees of third-party services, making it ideal for developers handling multiple websites or projects with high traffic.

Top Benefits of Self-Hosted Forms for Security & SEO Success

Switching to self-hosted forms, such as Form2Mail, gives businesses control over data flow and reduces vulnerabilities. Unlike public platforms, self-hosted forms are directly tied to your domain, increasing user trust and ensuring all interactions remain under your control.

Beyond security, self-hosting offers SEO advantages. Keeping users on your domain improves engagement metrics, reduces bounce rates, and enhances your site's ranking potential. For tips on how user engagement impacts SEO, see Moz's SEO Guide.

Form2Mail vs. Formspree vs. Google Forms: Comparing Self-Hosted and Cloud Form Submission Solutions for Static Sites

Race to Form Success: The Great Form Showdown!
Race to Form Success: The Great Form Showdown

When choosing a form submission tool for static websites, developers must weigh the benefits of self-hosted and cloud-based solutions. Let’s compare Form2Mail, Formspree, and Google Forms based on pricing, customization, and advanced features.

Formspree Overview

Formspree is a cloud-based form submission service that provides an easy setup for handling forms on static websites by using an action URL directly in the HTML form. It’s popular for its simplicity and ease of integration.

  • Pricing: Formspree offers a free tier with up to 50 form submissions per month, but once you exceed that limit, paid plans start at $10 per month.
  • Customization: While it supports AJAX form submissions and basic spam protection like reCAPTCHA, Formspree’s design customization is limited. Advanced features, such as integrations and form validation rules, require paid plans.
  • Security: Formspree processes data through its servers, which may raise security concerns for sensitive information. Although the service does provide TLS encryption, it does not offer the same control as self-hosted alternatives like Form2Mail.

Learn more about Formspree’s pricing and features.

Google Forms Overview

Google Forms is a free form-building tool popular for simple surveys and data collection tasks. While easy to use, it has significant limitations that may deter developers working on more advanced static sites.

  • Pricing: Google Forms is free, with no limits on the number of forms or submissions, making it a great choice for basic use.
  • Customization: Google Forms is restricted in terms of design. You can't fully customize the form to match your website’s branding, which might lead to inconsistent visual elements.
  • Advanced Features: Google Forms lacks the ability to handle more complex workflows, such as advanced conditional logic or multi-step forms. Additionally, it has no native integrations for payment processing, limiting its usability for businesses that need to handle transactions.
  • Security: While it offers basic security features like SSL encryption, file upload restrictions require users to be logged into Google, which can disrupt the user experience. Moreover, Google Forms does not support file uploads without requiring Google account authentication, limiting accessibility.

Form2Mail Overview

Form2Mail is a fully customizable, self-hosted form submission API that is ideal for static site developers who need complete control over their data and functionality. It offers unmatched flexibility, security, and scalability.

  • Pricing: Form2Mail is open-source and free to use under the Apache 2.0 Licence, making it highly cost-effective compared to subscription-based services like Formspree.
  • Customization: Unlike Google Forms or Formspree, Form2Mail gives you full control over the form’s design and functionality. You can adjust everything from field validation to SMTP configurations, ensuring your form integrates seamlessly with your website’s branding.
  • Advanced Features: With Form2Mail, you can implement advanced logic, custom error handling, and API key authentication, ensuring secure and customized form submissions. This level of control is unmatched by cloud-based alternatives.
  • Security: Since it’s self-hosted, all data is processed on your server, which means you don’t rely on third-party servers to handle sensitive information. This provides greater security for businesses handling private user data.

Which Solution Should You Choose?

  • Google Forms: Best suited for basic surveys or quizzes, especially if you're looking for a free solution with no customization needs. However, it lacks advanced features, customization options, and security measures, which can limit its usability for business and e-commerce websites.
  • Formspree: Ideal for developers who need a quick and simple setup but are okay with paying monthly fees for advanced features and integrations. Its limited customization and reliance on third-party servers make it less appealing for users needing more control over data security and branding.
  • Form2Mail: Perfect for developers managing static websites who require complete control over form functionality, security, and customization. With no ongoing fees and full server-side processing, Form2Mail provides a flexible, cost-effective solution that scales with your needs.
