How to Put Mailchimp on WordPress

Mailchimp and WordPress Work Better Together

To embed Mailchimp in WordPress, create a form in Mailchimp, copy its code, then add it to a WordPress page or widget. You can also use a WordPress plugin to place forms without editing code. Both methods help collect email sign-ups and send campaigns from one subscriber list.

Mailchimp is an email marketing platform. It helps you build lists, send campaigns, and set up email automation. WordPress gives you the site where visitors can join that list.

This setup keeps your list in Mailchimp. You can then group contacts, send welcome emails, and review campaign results. Your site handles sign-ups while Mailchimp handles email delivery.

The best method depends on your site and skill level. A plugin suits most users. An HTML form gives you more control over placement and markup.

Get Ready Before You Connect

First, create a Mailchimp account and confirm your sending details. A confirmed email address helps protect your sender reputation. It also reduces failed sends later.

Next, create an audience in Mailchimp. An audience is the main list that stores your contacts. Give it a clear name, such as “Theme Waves Newsletter.”

Then decide where visitors should join. A footer form suits every page. A sidebar form works well on blog posts. A pop-up can gain attention, but use it with care.

Before you start, check your WordPress access. You need permission to install plugins or edit page content. You also need a page builder or block editor if your site uses one.

• Admin access to the WordPress site
• A welcome email or follow-up plan
• A clear reason for visitors to subscribe

How to Embed a Mailchimp Form in WordPress

There are two common ways to put Mailchimp on WordPress. You can use a plugin, or you can paste an HTML code snippet. Start with the plugin method if you want the fastest setup.

Method one: use a WordPress plugin

Search the WordPress plugin directory for a Mailchimp form plugin. Check its update date, user rating, and support history. You can also review Mailchimp's website form instructions before you begin.

Install and activate the plugin. Most plugins ask for a Mailchimp API key. This key lets the plugin connect your site with your Mailchimp account.

Open the plugin settings and add your API key. Select the audience that should receive new subscribers. Then choose the fields you want to show.

Keep the first form simple. Ask for an email address and, if needed, a first name. Each extra field can lower sign-up completion.

Copy the form shortcode or block supplied by the plugin. Add it to a page, post, footer, or sidebar widget. Publish the change, then test the form in a private browser window.

Method two: paste Mailchimp HTML code

Open Mailchimp and find its embedded form builder. Pick your audience and adjust the visible fields. Mailchimp will then create HTML code for the form.

Copy the full code snippet. In WordPress, open the page or widget where the form should appear. Add a Custom HTML block and paste the code inside it.

Save the page and test the form on a phone and desktop. Submit a test address that you can access. Check that the address appears in the correct audience.

HTML gives you direct control over the form structure. It may need extra CSS for a close visual match. Use the plugin method if you do not want to edit markup.

Customize Forms to Match Your WordPress Site

A form should look like part of your site. Match its font, spacing, button shape, and color. Keep the main action easy to spot.

Start with the form fields. Most sites need only an email field and a first name field. Explain what subscribers will receive near the form.

Use a short call to action. “Get weekly design tips” tells visitors more than “Subscribe.” Set a clear expectation about email frequency when possible.

For plugin forms, use the plugin's style settings first. Add custom CSS only when those settings fall short. Test changes on small screens after each major edit.

For HTML forms, edit the surrounding layout in WordPress. Avoid changing hidden Mailchimp fields unless you know their purpose. A small markup error can stop sign-ups.

Form location	Good use	Watch for
Footer	Reach visitors on every page	Low attention near the page end
Sidebar	Support blog and resource pages	Weak display on mobile screens
Pop-up	Gain focus at a key moment	Annoying visitors who read quickly
In-content	Offer a related download or update	Breaking the reading flow

Best Ways to Use Mailchimp on WordPress

Placement has a direct effect on list growth. Add one form in a steady site location. Then test one stronger placement, such as an in-content form.

A blog post can offer a related email series. A product page can offer setup tips. The offer should fit the visitor's current task.

Pop-ups can work well after a visitor shows interest. Set a delay or exit rule so the form does not appear at once. Do not show it on every page view.

Use one audience with clear groups when possible. Groups can separate readers by interest. This makes later email sends more useful.

Set up a welcome email soon after sign-up. Tell new subscribers what happens next. Keep the first email focused on one helpful action.

Review Mailchimp reports each month. Check opens, clicks, unsubscribes, and sign-up sources. Compare results after each form or offer change.

• Place a simple form in the footer or sidebar
• Test an in-content offer on high-traffic posts
• Use a clear benefit beside every form
• Send a welcome email soon after sign-up
• Review campaign metrics before changing your plan

Fix Common Mailchimp and WordPress Problems

If the form does not show, check the block or shortcode first. Make sure the plugin is active. Clear any page cache and test again.

If the form shows but does not submit, check the API key. A deleted or changed key can break the connection. Create a new key in Mailchimp when needed.

If new contacts do not appear, check the audience and sign-up status. Some lists require email confirmation. Look in Mailchimp for pending contacts.

If the form looks wrong, inspect your theme styles. Theme rules can change field widths, fonts, or button colors. Test the form with a simple page template.

If emails land in spam, review your sender details and email content. Avoid sending from a free address when your domain supports a better option. Keep your list clean by removing inactive contacts over time.

Test every form after plugin updates. A two-minute test can catch a broken field or wrong audience. Check both desktop and mobile views.

Next Steps After You Add the Form

Once the form works, focus on the reason people should join. Offer useful updates, a short email course, or a helpful resource. Make the benefit clear beside the form.

Start with one audience and one welcome email. Add more automation after you see steady sign-ups. This keeps your Mailchimp setup simple while you learn what readers want.

Track sign-ups by placement when possible. Compare footer forms, pop-ups, and in-content forms over four weeks. Keep the spots that bring useful subscribers.

Now you know how to use Mailchimp in WordPress with either a plugin or HTML. Choose the simpler route first. Improve the design and placement after the basic connection works.
