Create an Email Signup Form with Klaviyo

Paradoxically, one of the most effective secrets to capturing your customers' attention is often underutilized: email forms. Especially when they are created with Klaviyo, a tool specially designed to optimize your marketing strategy.

In this guide, we will detail the creation of Klaviyo forms step by step, from configuration to integration on your site. Objective: high-performing forms that convert your visitors into customers.

Introduction to Klaviyo forms

Klaviyo is one of the most advanced email marketing platforms on the market. It allows you not only to manage your campaigns but also to design attractive and personalized signup forms. According to HubSpot (2024), optimized forms generate an average of 74% more leads compared to standard forms.

Why email forms are essential

Signup forms represent the gateway to your CRM strategy. They collect valuable data (emails, first names, preferences) and then trigger automated campaigns. Campaign Monitor (2023) reveals that personalization based on forms increases conversion rates by 26%.

With Klaviyo, information collection becomes a strategic asset: advanced segmentation, seamless integration, immediate automation.

Initial Klaviyo setup

Before creating a form, you need to configure your Klaviyo account: simple registration, importing your contacts, preparing segments. This step ensures the quality and reliability of your data.

👉 Real example: an e-commerce brand doubled its subscriber rate after correcting a simple CSV formatting issue during contact import.

Steps to create an email form

1. Choose the form type: pop-up, flyout, embed… Each format has its advantages.
2. Personalize the design: consistency with your brand's graphic charter.
3. Configure strategic fields: name, email, preferences, but without overloading the form.
4. Set up automation: trigger a welcome email upon registration.

⚡ Concrete example: an independent bookstore gained +35% subscriptions by reducing its form to 2 simple fields (first name + email).

Integrating the form on the website

Code generation

Klaviyo automatically provides an integration code. Copy-paste, and the form is ready to go.

Placement on the site

The code can be placed in your header, footer, or on a dedicated landing page. Good placement can increase your capture rates by 40% (DMA, 2023).

Tests and validation

Always test before going live: fields, buttons, confirmation messages. The first impression is crucial for your prospects.

Optimization & best practices

• Simplify your forms: fewer fields = more sign-ups.
• Adjust the timing: a pop-up displayed too early can harm the user experience.
• Personalize messages: the more your forms reflect your brand, the more they inspire trust.
