Create and Add a Mailchimp Form: Step-by-Step

To get the most out of your Mailchimp form, it’s essential to set it up properly. Below is a detailed step-by-step walkthrough on how to create and configure the widget using Elfsight’s intuitive form builder. This guide covers everything from layout settings to Mailchimp integration and final installation.

1. Start by building the form. Launch the editor and select a suitable form template. Create the form with the AI form generator or manually add all the necessary fields such as Name and Email using the drag-and-drop panel.
2. Set up email notifications. Configure alerts for yourself and autoresponder messages for subscribers. You can also customize sender email settings through SMTP.
3. Customize layout preferences. Head to the Layout tab and choose the embed type (Inline or Floating), adjust width, and pick between Vertical, Horizontal, or Multistep layout.
4. Edit the form’s appearance. In the Appearance tab, select a color scheme, accent colors, and font. You can also change background, header, and button styling for a consistent look.
5. Adjust form settings. Set the post-submit action, enable spam protection, change language, pre-fill fields via URL parameters, and even add custom JS.
6. Connect Mailchimp. In the Integrations tab, choose Mailchimp and authorize access. This ensures all form entries sync directly with your Mailchimp lists.
7. Copy and embed the form code. Click “Add to website for free”, then copy the HTML form snippet. Paste it into your website’s HTML editor or block section to publish your embedded contact form.

Following these steps ensures your form is not only visually appealing but also fully functional and optimized for lead capture.

This completes the full setup of your Mailchimp embedded contact form. With the right configuration, responsive layout, and seamless integration, your form will start collecting leads and growing your newsletter list in no time. Let’s now look at other available ways to add a Mailchimp form to a website.

Other Ways of Mailchimp Form Integration

In addition to Elfsight, there are manual options available to place a Mailchimp form directly on your website. These native methods don’t require third-party platforms and are ideal for users who are comfortable working with code or want to stay within Mailchimp’s own ecosystem.

Below are two reliable methods: using Mailchimp’s built-in embed code and writing a custom HTML form manually. Follow the detailed instructions to implement each method properly.

Using Mailchimp’s Native Embed Code

This method allows you to use Mailchimp’s default form generator and copy a ready-to-use code block. It’s a quick solution for basic integrations and doesn’t require technical setup beyond pasting HTML into your website’s code.

1. Log into your Mailchimp account. From your dashboard, select the audience where you want to add new subscribers.
2. Open “Signup Forms”. In the navigation bar, go to “Audience” > “Signup forms”, then click “Embedded forms”.
3. Choose a form layout. Select the form type you prefer: Classic (standard layout), Condensed (minimal), Horizontal (inline with content), or Unstyled (for full customization).
4. Configure form settings. Toggle checkboxes for elements like the form title, required field indicators, GDPR fields, or interest groups, depending on your audience preferences.
5. Copy the generated embed code. Scroll to the “Copy/paste onto your website” box, highlight the HTML snippet, and copy it.
6. Paste the code into your website. Open your HTML editor, navigate to the section where you want the form placed, and paste the code. Save and publish your changes.

This method is best for simple form placements where default styling is sufficient or if you’re comfortable modifying the code yourself.

Manually Writing a Mailchimp-Compatible HTML Form

This approach gives you full control over your form’s structure and behavior. It requires knowledge of HTML and Mailchimp’s submission protocols. This method is ideal if you want to hand-code a fully customized form without using embed generators.

1. Get your Mailchimp action URL. In Mailchimp, go to “Signup forms” > “Embedded forms”, click the “Unstyled” form option, and locate the form action URL in the HTML. It usually starts with https:// and contains your list ID.
2. Create a basic form container. In your HTML file, use the <form> tag with method=”POST” and insert the action URL in the form’s action attribute.
3. Add required input fields. At minimum, include an email input field with name=”EMAIL”. You can also add fields like FNAME and LNAME for first and last names if your list setup requires them.
4. Set hidden fields and identifiers. Add any hidden input fields such as u and id (provided in the Mailchimp embed code) to ensure the form submits to the correct audience list.
5. Insert a submit button. Use a styled button with type=”submit” to trigger the form submission. Label it “Subscribe” or “Join Now” as appropriate.
6. Style the form using CSS. Apply inline styles or link to a separate CSS file to define layout, spacing, font, colors, and responsiveness. This ensures the form matches your website’s design.
7. Test the form. Submit a test entry to verify that data is sent to Mailchimp successfully. Make sure confirmation or redirection works as expected.

This method is powerful for custom projects but requires attention to detail and familiarity with HTML form structure and Mailchimp’s field naming conventions.

Comparison: Elfsight vs Other Methods

Here is a detailed comparison of using Elfsight versus native Mailchimp methods, highlighting both their advantages and trade-offs to help you decide which fits your workflow best:

Method	Pros	Cons
Elfsight Form Builder	Offers a user-friendly drag-and-drop interface with full design control, automation, and Mailchimp integration — all without touching code.	Requires a third-party account to manage forms and access the editor interface.
Mailchimp Native Embed Code	Fast to implement with no installation needed — copy the code directly from your Mailchimp dashboard and paste it into your website.	Limited design flexibility and requires manual CSS editing to match your website’s branding.
Manual HTML Form	Gives you total control over structure, design, and advanced behavior through hand-coded HTML and CSS.	Requires technical knowledge, and small mistakes can easily break form functionality or result in failed submissions.

Now that you’ve explored all major options for Mailchimp form integration, let’s go over practical tips to ensure your form performs well once it’s embedded on your website.

Tips to Make Your Form Work Better

Once your Mailchimp form is embedded, there are several best practices that help ensure it performs well, looks good on every device, and integrates smoothly with your overall website layout. Here’s what to keep in mind before and after installation:

• Place your form where users expect to see it. For signup forms, the best placement is usually in the website footer, sidebar, or as a sticky bar at the top. Avoid burying it deep within the page.
• Always use a responsive layout. Choose a layout that automatically adapts to mobile, tablet, and desktop screen sizes. This prevents fields and buttons from breaking on smaller screens and keeps the form accessible.
• Keep the form short and focused. Request only essential information — usually a name and email. Extra fields reduce completion rates and may overwhelm first-time visitors.
• Use clear call-to-action text. Replace generic buttons like “Submit” with more engaging phrases such as “Subscribe Now” or “Get Updates”. This boosts clicks and helps guide users through the process.
• Style the form to match your website. Align fonts, colors, and button designs with your brand identity. A consistent look builds trust and reduces visual friction.
• Test the form across different devices. Preview your website on desktop, tablet, and mobile after embedding the form. This helps catch layout issues early and ensures full accessibility.
• Enable auto-confirmation messages. Always set a visible confirmation or thank-you message to notify users their submission was successful. It improves UX and reduces confusion.
• Use spam filters wisely. If you’re enabling CAPTCHA or honeypot fields, test them first to ensure they don’t block real users or interfere with form delivery.
• Integrate with automated email sequences. Link your form to welcome emails or subscriber workflows to engage users as soon as they sign up.
• Track performance with analytics. Use your website analytics tools to monitor form views, submission rates, and user interactions to optimize placement and design further.

These practices will help your Mailchimp signup form function smoothly and convert more visitors into subscribers. In the next section, we’ll look at who benefits most from using embedded forms and explore common use cases across different industries.
