Hyper-Personalize Your Marketing

Klaviyo is the leading growth marketing platform for ecommerce. Integrating Gender-API enables you to enrich customer profiles with accurate gender data for hyper-personalized email and SMS campaigns.

By knowing your customer's gender, you can recommend relevant products, tailor content, and segment your audience precisely to drive higher engagement and conversion rates.

Why Integrate Gender-API with Klaviyo?

Automated Enrichment: Update new profiles automatically.
Personalized Content: Show gender-specific products and offers.
Smart Segmentation: Create targeted audiences for better ROI.
Omnichannel: Use gender data across Email and SMS.

How It Works

The integration is powered by Zapier and works in the background. As soon as a customer joins your list, they are enriched.

1. New Profile

When a new customer profile is created in Klaviyo (via signup or purchase), Zapier triggers the workflow and sends the first name to Gender-API.

2. Enrich Profile

Gender-API returns the gender and confidence score. This data is added to the Klaviyo profile as a custom property, ready for use in flows and segments.

Use Cases

Fashion: Suggest men's vs women's collections.
Beauty: Recommend gender-specific products.
Gifting: Curate relevant gift guides.
Fitness: Customize workout plans.
SMS: Send personalized text offers.
Welcome Flows: Tailor the first impression.

Frequently Asked Questions

01

How do I use this in email templates?

Use dynamic variables (e.g., {{ person|lookup:"Gender" }}) or show/hide content blocks based on the custom property "Gender".

02

Can I enrich existing profiles?

Yes. Export profiles, process via Gender-API, and re-import. Or use a "Profile Updated" trigger to enrich gradually over time.

03

Does it work with SMS?

Yes! The data lives on the profile, so it is accessible to all Klaviyo channels including Email, SMS, and Push.

04

What about ambiguous names?

We provide a confidence score. You can choose to only set the gender if confidence is high, or mark it as "Unknown" to play it safe.

05

Is it compliant?

Yes, using first-name based gender inference for personalization is generally compliant (GDPR/CCPA) when done responsibly. We handle data securely.
