In a recent Business Bloomer Club Slack thread, the conversation turned humorous — but also insightful — thanks to one little change in WooCommerce 9.9. If you or your clients suddenly see “Cha-ching!” in new order email subjects, it’s not a mistake. It’s a feature.
Starting from version 9.9, WooCommerce introduces a small but loud addition: the default subject line of new order emails now says:
[{site_title}]: Cha-ching! You’ve got a new order: #{order_number}
This only happens if the new “Email Improvements” setting is enabled — part of the ongoing efforts to modernize the WooCommerce email system.
Where is this coming from?
The change comes from this updated method:
public function get_default_subject() {
return $this->email_improvements_enabled
? __( '[{site_title}]: Cha-ching! You\'ve got a new order: #{order_number}', 'woocommerce' )
: __( '[{site_title}]: New order #{order_number}', 'woocommerce' );
}
So yes, “Cha-ching!” is the new default — and many users have already noticed it.
Why this matters
It signals a shift in tone
This is more than a fun soundbite. WooCommerce is actively rethinking how its communication feels — not just functions. The team is experimenting with more expressive, engaging phrasing to better match modern ecommerce brands. The hope is to make WooCommerce feel less technical, more human.
It may catch store owners off guard
Not everyone will appreciate the surprise. Agencies and developers managing client stores should be aware that this subject line might trigger questions like:
- “Why does it say Cha-ching?”
- “Can I change that?”
- “Is this WooCommerce or some plugin?”
If needed, this can be customized using the standard email subject filters or overridden via the admin settings.
What to expect next
This tweak is part of a larger effort around email improvements, which may include updated content, cleaner designs, and better performance. So while “Cha-ching!” might be the headline grabber, the long-term goal is improving how WooCommerce handles order notifications in general.
Love it or hate it — now you know where it’s coming from.
