How to Add a Mailchimp Signup and Pop-up Form to RebelMouse

When used in a smart way, pop-up forms can be a powerful tool for growing audiences, generating leads, and creating loyalty.

If you have a Mailchimp account, you can easily set up a pop-up form on your RebelMouse site by following these simple steps:


1.First, connect your website to publish your pop-up form on your site.

You will find a prompt to connect your site in the pop-up form builder.

2.Then, enter your website URL and click "Get started."

3.Next, copy the snippet of code that Mailchimp generates.

You will need to paste this code in Layout & Design Tool.

4.Paste the code in the Top Bar of the Header Code element in Layout & Design Tool.

5.To finalize, click the green "Check Connection" button in Mailchimp.

6.This is how the Mailchimp form builder will look once your site is connected.

7.To set up the pop-up form, navigate to your Lists in Mailchimp.

Navigate to the Lists page.

8.Choose the list you want to work with and select "Signup forms."

Click the drop-down menu next to the list you want to work with, and choose Signup forms.

9.Choose "Subscriber pop-up."

10.Customize the form.

After you've chosen Subscriber pop-up, you'll have a variety of options to customize your pop-up in the form builder.

You can navigate between three tabs to create your form:

  • Design
  • Fields
  • Content

This is where you'll choose the format of your pop-up form, as well as when it should be displayed to people who visit your site. You can also add and style field labels, call-to-action buttons, and custom messaging.

To help grow your subscriber list, the pop-up form is set to single opt-in by default. If you prefer, you can make your form double opt-in at anytime.

To customize your pop-up form, follow these next steps.

11.Use the "Design" tab to create the form's format.

You can choose between:

  • Modal to display the form in the center of your site.
  • Slide to have the form slide in and display in a fixed position on the bottom-righthand side of your site.
  • Fixed to display the form in a fixed position at the bottom of your site. This format only shows an email address field and body text on your form. Choose another format to display additional fields, footer text, or an image.

12.Use the "Design" tab to adjust when the form displays.

Click the Display drop-down menu to choose when your form should appear to people who visit your site.

13.Use the "Design" tab to adjust styling elements.

You can set image alignment and styles for the field labels, button, and pop-up modal here.

14.Use the "Fields" tab to choose the fields you want to show on your form.

Check the box next to each field you want to include in your form.

To require a field, toggle the Required slider on (it'll display a checkmark).

15.Use the "Fields" tab to reorder your fields.

To reorder a field, click the More Options icon (three dots) next to it and drag the field to where you want it to appear in your form.

16. Use the "Content" tab to add images and text.

Add the image and text you want to include in your pop-up form.

17. Review how your pop-up form looks on mobile devices.

You can make sure your pop-up form is mobile-friendly here.

18. Preview the banner.

To comply with mobile best practices, MailChimp defaults to a banner when your form is viewed on a mobile device. Visitors can tap the banner button to access your form.

19. Generate the code for your form.

When you're happy with how your pop-up looks, click the Generate Code button in the bottom-righthand corner.

20. Log in to your RebelMouse site and navigate to the "Top Bar" element in the Layout and Design tool.

  • Once you're logged in, choose the Layout and Design tool.
  • Choose the Top Bar element.

21. Create a "Custom HTML" element and paste your MailChimp code.

  • Create a Custom HTML element.
  • Give it a friendly name you can recognize it by, such as "MailChimp Pop-up."
  • Paste the generated code from MailChimp (step 13).
  • Click Save.

22. Your pop-up is now live!

Your pop-up form will display when someone visits your site. If they choose to fill out and submit your form, we'll add them to your MailChimp list.

If a visitor has previously viewed your form, MailChimp uses cookies to make sure they don't see it again for up to one year (or until they clear their cookies).

23. Need to make additional changes? Edit the form.

After you add the pop-up form's code to your site, you may need to make additional changes to the form.

To edit the form, follow these steps:

  • Navigate to the Pop-up Form builder.
  • Click on any tab (Design, Fields, Content) and make your adjustments.
  • Click Publish.
  • When the pop-up confirmation window appears, click Publish again.

24. How to remove the form.

  • Navigate to the Top Bar element in the Layout and Design tool of RebelMouse.
  • Remove the Custom HTML element that contains the MailChimp code. (We named ours "MailChimp Pop-up" back in step 15.)
  • Click Save.

25. Additional tips from MailChimp to consider.

  • Fields that are required in your list are not automatically marked as required on the pop-up signup form. Mark fields as required in the Fields tab.
  • Group fields can be required on the pop-up signup form. This isn't an option on our hosted or embedded signup forms.
  • Set the Overlay Opacity from 1–100, where lower values are more transparent and higher values are more solid. Use only numbers — the setting won't work if you use text or other characters, like %. If you leave the Overlay Opacity field blank, the pop-up will default to something that works for most sites.
  • Make sure you customize your form's related pages and response emails.
  • To help prevent fake signups, you can add reCAPTCHA confirmation to your pop-up form in your list's settings.

Google Made Major Changes to Its Formula for Page Speed. Here’s What to Do About It in 2022.

Make sure your site is set up for success in 2022.

In the spring of 2020, Google let the world know that its Core Web Vitals would become the new benchmark for measuring a site's performance in its search results, known as the page experience update. Fast forward to more than a year later in August 2021 when, after much anticipation, Google's page experience update became official.

Since its rollout, developers have felt the impact of how their publishing platforms stack up against the new standard. Important decisions around the architecture of your site can now make or break your site's performance in the eyes of Google.

HTTP Archive, a tracking platform that crawls the web to identify trends and record historical patterns, has revealed how top content management systems (CMS) have weathered the page experience update through the creation of its Core Web Vitals Technology Report. RebelMouse consistently outperforms major CMS platforms on Google's most critical metrics since its rollout and into 2022:

Getting superior scores on Google's performance benchmarks isn't easy, either. The Ahrefs blog analyzed Core Web Vitals data from the Chrome User Experience Report (CrUX), which is data from actual Chrome users, to see how the web stacks up against Core Web Vitals. Their study found that only 33% of sites on the web are passing Core Web Vitals.

data from Ahrefs tracked on a line chart finds that shows only 33% of sites on the web pass Google's Core Web Vitals From Ahrefs.

Luckily, performing well on Core Web Vitals is possible with thoughtful, strategic changes to your site’s codebase. Here's what you need to know and how we can help.

In 2022, Publishers Take Back Control With Subscription Success

Users are ready to pay for content that delivers

The Rise of the Mature User

It's been a long and winding path, but in 2022 the subscription model continues its upward trajectory as a top revenue strategy for publishers of all sizes. The tug of war between platforms and publishers reached its peak in the last few years of the previous decade, leaving users desperate for a modern user experience that's clear of any clutter from the duopoly that is Google and Facebook. This is why intelligent paywall models are a top choice for users looking to consume content right from the source. When done correctly, the strategy can work for any type of media. The New York Times, a frequent showpiece example of the power of paywalls, is constantly reporting record-busting subscription numbers, with 7.6 million digital subscriptions in 2021.

And it all makes perfect sense. The subscription model eliminates the middleman — such as the platforms — so readers get the experience and content they want, and publishers get the cash they need.

It’s been more than two years since Google let the world know that its Core Web Vitals metrics are the new benchmark for measuring a site's performance in its search results. Developers have since felt the impact of how their publishing platforms stack up against the new standard. Important decisions around the architecture of your site can now make or break your site's performance in the eyes of Google.

Now, the definition of what makes up Core Web Vitals could change. A new responsiveness metric called Interaction to Next Paint (INP) may replace First Input Delay (FID). During Google’s I/O conference in May 2022, it was announced that the INP metric was still in its experimental phase. You can watch the announcement here:

Most publishers are bogged down with day-to-day content strategy and creation, which usually means their technology suffers. That translates into poor search rankings, traffic dips, and loss of revenue.

Even so, the idea of replatforming to a new CMS, migrating your data, and overhauling your site’s architecture can sometimes feel more daunting than simply fixing the issues your website currently faces. But the stumbling block here is that most publishers aren’t even sure what the exact problems are with their current site.

That’s why RebelMouse offers a free website health check. This comprehensive audit will help you make a data-backed decision on what the best and most cost-effective next steps are to brighten your site’s future. Here’s what our health check includes:
