Above all, you have to know that WooCommerce has built-in fields validation including email, phone number, or postcode.

Flexible Checkout Fields lets you certainlty use these default rules for your custom checkout field validation.

👉🏽This way you can easily add email verification to your WooCommerce checkout!

Furthermore, you can use your custom validation. Therefore, our users praise Flexible Checkout Fields as an efficient WooCommerce checkout validation plugin!

How to configure WooCommerce checkout email validation

Firstly, you can configure WooCommerce checkout email validation in two ways. It all depends on your needs. You can:

  • disable validation on the default Email field
  • add email validation to your custom field

👉🏽You can find an option in the field's configuration:

Enable WooCommerce checkout fields validation like email, address, or phone
Default email validation in WooCommerce checkout page

👉🏽There is a select box so you can simply select an option that you want:

  • Default
  • None
  • Email
  • Phone
  • Postcode

By default, only a few fields have built-in validation. Default WooCommerce checkout validation works for the Email, Phone, and Postcode fields. These fields have the "Default" option turned on. You can turn it off if you need to with the None option. This way you can disable the default WooCommerce checkout email validation.

As a result, you can see the fields with built-in default validation below:

By default, it validates the field like this:

You'll see an error message as a result...

for an invalid email address.

Invalid email address

To clarify, you can use this WooCommerce checkout email validation for your custom fields.

Create your custom field and select Email from the Text fields type box in the field's configuration:

flexible checkout fields custom fields
WooCommerce checkout validation plugin: Select E-mail field type
flexible checkout fields email validation woocommerce checkout
Checkout validation plugin: set default validation for email

So, let's try it. Enter invalid email addresses.
