How to Create a Klaviyo Popup to Grow Your Email List

How to Create a Klaviyo Popup to Grow Your Email List

Do you need to rapidly grow your list of Klaviyo subscribers? Are you using Klaviyo popups and embedded forms, but feel like you could be achieving better results?

If you answered yes to either question, this article is for you.

We’re going to show you how to supercharge your email and SMS lists by using Klaviyo and OptiMonk together. These two tools integrate with one another seamlessly, allowing you to use OptiMonk’s email pop-ups to encourage site visitors to subscribe, and then send out relevant messages using Klaviyo’s super-targeted email campaigns once they do.

If you have existing Klaviyo profiles, you might be asking yourself: wait, doesn’t the email marketing platform already support the creation of a sign-up form? It does, but Klaviyo’s sign-up forms are quite limited in comparison to what you can do with OptiMonk. 

That’s because OptiMonk is a dedicated popup tool that gives you many different options for capturing new subscribers with pop-ups that match your brand and convert incredibly well.

That doesn’t mean we don’t love Klaviyo! Once you have a visitor’s email, Klaviyo is the best tool to send the right messages to them.

So here’s the plan: first, we’ll outline some of the advantages of using OptiMonk’s email and SMS pop-ups for building your list, and then we’ll show you how to use both tools together.

Let’s get started!

1. Klaviyo popup vs OptiMonk signup form

In short, OptiMonk popups offer far more in terms of your ability to target users at different stages of the customer journey, options for customizing your popups to fit with your brand, and the ability to add custom fields and elements that boost your conversion rates.

It’s worth looking at the differences in more detail so that you can evaluate exactly how OptiMonk’s capabilities can benefit your ecommerce business.

Klaviyo’s signup form comes in 3 different varieties: popup, flyout, and embed. 

Once you’ve chosen the style of your Klaviyo popup, you can pursue one of the following 5 goals:

  • Collect email subscribers
  • Collect phone numbers
  • Collect emails & phone numbers
  • Announcements
  • Know your customer

When you start creating a signup form with Klaviyo, you’ll see this screen:

Once you choose what type of signup form you’re going to use and what goal you’re after, that’s it—there’s not a whole lot more you can do to customize it. 

You’ll be able to add elements like text fields, buttons, and a background image to your Klaviyo popups, but as you’ll see in a moment, OptiMonk offers far more options.

OptiMonk not only offers more options in terms of the types of campaigns you can run, but it also has a powerful drag and drop editor so you can design your popups from scratch. 

And, if you’d rather use a template, there are over 300 in OptiMonk’s massive Template Library—all of which look equally great on desktop and mobile devices.

OptiMonk popup templates

With OptiMonk, you can choose from 6 (rather than 3) ways of getting your message across: 

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

In addition to building your email and SMS lists, OptiMonk offers templates for other goals, like:

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

This means that once you get started with email signup forms on OptiMonk, it’s easy to create other types of campaigns that will lead to more sales.

For example, using an OptiMonk cart abandonment popup can “rescue” up to 30% of your departing traffic!

You can also find popup templates for holidays and seasonal events like Black Friday, Christmas, and Summer or Back to School sales.

Check out below some of the ready-to-use popup templates OptiMonk offers:

OptiMonk allows you to create almost any layout you can imagine and add custom content. You can add the same great standard functions as with a Klaviyo popup (Text, Image, Button), but you can also add more interesting elements like:

  • A Countdown Timer to create a sense of urgency.
  • A Video so you can present your product, solution, or story in a more engaging way.
  • A Coupon Code to easily offer discounts in exchange for an email address.
  • A Product Component that helps to upsell and cross-sell, increasing your average order value.

That’s not even close to the full list of what you can do in OptiMonk’s popup editor. And the best part of all? You won’t need to write a single line of code!

Now, here’s the most important part: Klaviyo lacks some of the targeting, triggering, and segmentation options that OptiMonk offers. 

This is crucial, because displaying the right message at the right moment to the right person is the key to a successful popup campaign.

With Klaviyo, you can display your popup immediately when the page loads or you can delay the appearance using a scroll-based or time-based trigger.

In terms of targeting specific segments of visitors, your options are: using a curated Klaviyo list, using specific web page URLs, or using geo-location.

Targeting settings including "don't show to existing Klaviyo profiles"

That’s not bad, but once again you have lots more targeting and triggering 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

And now for OptiMonk’s targeting options! There are tons, so we won’t give you an exhaustive list, but here are a few of the ways you can show different popups to different segments of site visitors: 

  • Block IP Addresses: Visitors with specified IP addresses won’t see your message
  • Exclude Page Visitors: Excludes visitors who have already visited a custom HTML page
  • Cart Rules: Visitors with specific items in their carts will see your message
  • Cookie Segmentation: Segment your audience based on any cookie you want

Need we say more? 

As you can see, OptiMonk is the best option for creating an email sign-up form (and many other types of popups). Now, let’s look at how you can deliver relevant emails to all the contacts you’ve gathered using Klaviyo.
