Ultimate Guide to Using Mailchimp and WordPress (2023)

Are you looking for a guide to using Mailchimp with WordPress?

Mailchimp is one of the most popular email marketing services, and it can be easily used with your WordPress website.

In this guide, we’ll show you how to easily integrate Mailchimp in WordPress and start building your email list.

Using Mailchimp with WordPress
Following is a quick overview of the topics we’ll cover in this guide.

Why Build an Email List?

More than 70% of users who abandon your website will probably never come back, unless you successfully get them to subscribe to your email list.

Email is private, personal, and by far the most direct form of communication on the internet. Many people check their inbox more than their social media feed.

Plus, an email will stay in the inbox unless a user takes action on it. On social media, your message will soon get buried in an endless timeline.

For more details on how email marketing can grow your business, see our guide on why you should start building your email list right away.

Why Use Mailchimp with Your WordPress Site?

Mailchimp is one of the most popular email marketing services. Why? Because they offer a free forever plan where you can send up to 10,000 emails per month to no more than 2000 subscribers.

Now, as your subscribers grow to more than 2000 or you need to send more emails, then you’ll need a paid plan which can get quite expensive.

Apart from email marketing, Mailchimp also offers basic automation tools that come in handy in growing your business online.

However, Mailchimp is far from perfect. They are no longer the easiest or the most cost-effective email marketing service on the market.

Some Mailchimp alternatives like Constant Contact, Drip, and HubSpot offer more advanced marketing automation tools that are easier to use.

Other companies like Sendinblue and ConvertKit also offer a forever-free plan.

That being said, let’s see how to use Mailchimp with WordPress to grow your business and start building your email list.

Getting Started with Mailchimp

To connect Mailchimp to your WordPress site, the first thing you will need is a Mailchimp account.

To get started, visit the Mailchimp website and click on the ‘Sign Up Free’ button at the top right.

Mailchimp sign up

Simply fill in your email and create a username and password for your account, and continue following the on-screen instructions to finish the account setup.

Once you have created your account, you’ll reach your Mailchimp dashboard, which looks like this:

Bonus: Tips to Grow Your Mailchimp Email List Fast

If you’re not promoting your email list to your website visitors, then you are losing potential subscribers, customers, and sales.

Following are some of the best proven tips that will help you grow your Mailchimp newsletter faster.

1. Multiple Sign up Forms

Use multiple sign up forms

Don’t just add one sign up form in the sidebar. Instead, give your users plenty of opportunities to sign up with multiple email subscription forms.

2. Use Gamification to Win Subscribers

Gamification brings fun interaction to your email forms. People are more likely to enter their email address if they have a chance to win something in exchange.

See our tutorial on how to add spin to win popups in WordPress.

3. Create Lead Magnets

Lead magnets are incentives that you can offer to your users in exchange for signing up to your email list. For instance, you can send them an ebook, a sample chapter, a discount code, and more.

4. Use Targeted Campaigns and Personalization

  1. Is there a way to use an embedded form to allow users to update their newsletter preferences without them having to type in their email? If they’re logged into WordPress, is there a way for the MailChimp form to already be prefilled with their email address and all they have to do is select the newsletters they wish to subscribe to and submit?

  2. I would like to make accessible the monthly MailChimp newsletters from a non-profit’s website so subscribers can access past newsletters.
    Thank you for any help you can provide.

  13. Hello,

    I am running a blog on with Rowling theme.

    I tried to add newsletter signup using Mailchimp following this guide, but once I put the copied Mailchimp’s standard (also superslim or naked) signup form code to Sidebar text widget – half of the code comes up as text. Moreover, the subscribe button does not work and fields that should be filled up do not show up (only their “titles/description”.

    I consulted the previous comments, but none of the solutions seem to be working.


    • I had the same issue at first. Then I found out I pasted the MailChimp’s standard text in the ‘Visual’ box instead of ‘text’ box. It’s a simple fix for me – just click ‘text’ and past the content in ‘text’ instead of visual.

  14. Amazing Article. This is probably my favorite site on the internet, right behind Google. I’m doing so much with WordPress and I admire how much hard work you put into it. Thanks a lot brother :)

  15. Can I only install plugins if I have a wordpress business plan? I have a personal plan and when I paste the code provided by mailchimp into a text widget on my blog sidebar, it just appears like code text on my sidebar instead of an email subscribe form. I don’t know why it’s happening, please help me.

  16. So I created my first email campaign for blog updates with mailchimp. I sent out a test update and it looks great. However, I am still receiving the old automated blog updates and I dont know how to delete them, so now everytime theres a new blog, people are getting 2 update emails about the same post. How do I delete the old blog identification? I don’t have anything other then mail chimp installed for this and I don’t see any other campaign for blog updates there that I can delete. please help.
