Last updated on Feb 1, 2018 by Lindsay Liedke

Do you want to create MailChimp subscribe forms in WordPress with personalized, custom form fields for your target audience? By adding custom fields to your MailChimp forms, you can gather special information like a site visitor’s birthday, for use in your email marketing.

In this article, we’ll show you how to create MailChimp custom fields in WordPress for creating more personalized email campaigns.

Why Use MailChimp Custom Fields?

Personalization is a powerful marketing tool to boost your revenue.

But, it can be tough to get started if you’re not very technically-inclined.

Luckily, MailChimp gives you an easy way to personalize your email campaigns by using custom fields.

What is a MailChimp custom field? A custom form field goes beyond the basics (name and email address) and asks subscribers for more information. You can ask your subscribers for their company name, website, birthday, and more.

This gives you an easy way to segment your email list to get better results.

One common way to use custom fields for eCommerce personalization is to ask for their birthday so you can send them an exclusive discount code on their big day.

That’s exactly what we’ll show you how to do in this tutorial – but you can use custom fields to ask for any kind of information you want.
