How to Redirect Existing Signup Forms to Klaviyo

Last updated at:


This guide explains how to redirect existing signup forms to point to Klaviyo, or otherwise ensure that all of your future subscribers are added to your Klaviyo account after switching from another email service provider.

If you're using one of our pre-built ecommerce integrations, like Shopify or BigCommerce, ecommerce platform-specific forms are synced automatically through the integration. Review the integration settings for your ecommerce platform to confirm these subscribers are automatically synced.

Additionally, Klaviyo offers popup, flyout, and embedded forms that come free with your Klaviyo account. Check out this guide to installing Klaviyo Signup forms.

As you consider importing contacts and connecting signup forms to Klaviyo, keep in mind that maintaining one primary newsletter list will make it easy to later manage and communicate with your contacts efficiently. The segment builder allows you to create dynamic segments of your lists that don’t require any maintenance. 

Redirect Existing Signup Forms

If you already have different signup forms on your website, you'll need to make sure that subscribers using these forms end up in Klaviyo. To start, consider the following: 


Redirecting a Custom Form to Klaviyo

If you're migrating over from Mailchimp, you will not be able to redirect existing forms to Klaviyo. Instead, leverage Klaviyo's native Signup Form Builder to create your forms.

If you've configured a custom form, this form likely has a Form Action URL that tells the form where to send new subscribers' email addresses. You will need to simply change this URL to the subscribe page URL for your Klaviyo list. To find this URL, navigate to the Subscribe Pages tab for the particular list.


Generally speaking, the form should have the following properties:

<form id="email_signup" action="//" method="POST">
  <input type="hidden" name="g" value="LIST_ID_HERE">
  <input type="email" value="" name="email" id="k_id_email" placeholder="Your email" />
  <button type="submit">Subscribe</button>
<script type="text/javascript" src="//"></script> 

Using a Third-Party Tool

Klaviyo integrates with a number of third-party list growth and landing page tools. Scan our list of available integrations to find yours. If you don't see your tool of choice on our list, we strongly encourage you to reach out to ask them to integrate with us.
