How to Make a Mailchimp Popup That’ll Double Your Subscriber List

Would you like to double your Mailchimp subscriber list? Are you already using Mailchimp popups on your website but not satisfied with the results you’re getting?

You’re in the right place!

In this article, we’ll take a look at a great alternative to creating Mailchimp popups. 

OptiMonk is a dedicated popup tool that’s tailored to the needs of ecommerce websites. And OptiMonk integrates with Mailchimp, meaning that you can use OptiMonk’s advanced popup capabilities while also taking advantage of Mailchimp’s great email marketing system.

Let’s have a look at how to boost your Mailchimp list-building campaigns by using OptiMonk and Mailchimp together!

1. A Mailchimp pop-up form vs. an OptiMonk pop-up form: What's the difference?

You might be wondering: why not just go with the convenience of using the popup form that comes as part of your Mailchimp account?

To put it simply, OptiMonk has many, many more options than Mailchimp when it comes to pop-up design, targeting, and triggering.

For starters, Mailchimp’s pop-up form editor doesn’t give you much freedom when it comes to design. You get access to one very simple, basic pop-up template design.

You have 5 options to choose from when it comes to the layout of this pop-up template.

These very limited design options can be a problem when you want to create signup forms that look like they belong on your website. Without the ability to customize your pop-ups, it’s difficult to make them fit the look and feel of your online store.

With a Mailchimp popup, you have the most freedom when it comes to editing the style of your text. You can choose the font, color, and paragraph style to use.

You can also upload an image and add extra form fields (like first name) to your pop-up forms.

Finally, in the settings, you can choose when to display your pop-up and its position.

Unfortunately, the settings end there in Mailchimp!

You don’t have any targeting options—your popup form will be shown to all website visitors on all pages. That will probably end up annoying your target audience, right?

Now, let’s take a look at what you can do with OptiMonk.

The most significant difference is that OptiMonk allows you to target visitors at different stages of the customer journey and tailor messages just for them. Since a visitor will never see an irrelevant message, they’ll be much more likely to subscribe to your Mailchimp list.

You also have a lot more options when it comes to pop-up templates. OptiMonk’s massive Template Library contains more than 300 beautiful pop-ups that you can choose from—all of which look equally great on desktop and mobile devices.

You can edit and customize each template using OptiMonk’s drag and drop builder. 

There’s a long list of elements you can add, including countdown timers, custom coupon codes, and product recommendations. That means you can create almost any layout you can imagine and add lots of custom content:

Using OptiMonk, you can choose signup forms that get your message across in 6 ways: 

  • Classic popups
  • Sticky bars
  • Sidemessages
  • Fullscreen popups
  • Gamification popups (Spin the wheel, Scratchcard, Pick a gift)
  • Embedded forms

Here are just a few of OptiMonk’s ready-to-use templates that are great alternatives for your Mailchimp form:

In addition to list-building campaigns, OptiMonk offers several other types of pop-up campaigns for different use cases:

  • Stopping cart abandonment with exit-intent technology
  • Promoting sales and discount offers
  • Collecting feedback
  • Recommending products or blog articles
  • Guiding your new website visitors with a welcome flow

When you have access to these other types of messages, your business can address more of its on-site messaging needs through a single account.

Finally, you have many triggering and targeting options with OptiMonk. Here’s the list of popup triggers that OptiMonk’s settings allow you to choose from:

  • On exit-intent
  • On-click to a specific area
  • After X percent scrolling
  • After X seconds of inactivity
  • After X seconds
  • After a JavaScript event

Here are a few of the ways you can show different popups to different segments of site visitors: 

  • Returning vs. new visitors
  • Based on traffic source
  • Based on cart rules
  • Based on country
  • Current page / URL
  • …and more!

The difference between creating a signup form in Mailchimp vs. OptiMonk

Marketers are realizing more and more that in order to display relevant, helpful popups to a visitor, the popup’s content needs to be personalized.

With all the advanced options you get with OptiMonk, you can start delivering different pop-up campaigns to different users based on their needs, preferences, and buying intent. 

For example, a user viewing your website for the first time might be more interested in helpful information like educational blog posts rather than a discount code.

You can make a single opt-in form using Mailchimp, but you can’t push your popup strategy any further than that. 

Personalization and advanced targeting will always be out of reach, as will other types of pop-up campaigns (like cart abandonment campaigns) that are important to the customer experience and the profitability of your online store.

It all boils down to this: OptiMonk is a dedicated popup tool, which means that you can do so much using the software that simply isn’t possible if you use a Mailchimp popup!

2. How to use your Mailchimp account and OptiMonk account together?

Now that we’ve seen why an online business using OptiMonk holds an advantage over one that uses a Mailchimp popup, let’s take a look at how to use OptiMonk to build your list and Mailchimp to send emails to your subscribers.

It takes less than a minute to set up the integration between Mailchimp and OptiMonk. All you have to do is navigate to the “Add Integration” menu in OptiMonk:
