Cart abandonment costs WooCommerce stores billions in lost revenue every year. Tracking those abandoned carts and sending recovery emails is one of the most effective ways to win back sales. But if any of your customers are in the EU, you need to think carefully about how you handle their data.
GDPR cart tracking in WooCommerce is not just a checkbox exercise. Get it wrong, and you risk fines, lost trust, and a reputation hit that no amount of recovered carts can fix. Get it right, and you can recover revenue while respecting your customers’ privacy.
Here is what you actually need to know.
Why Cart Tracking and GDPR Collide
Cart tracking works by capturing a shopper’s information before they complete a purchase. When they leave without buying, you use that information to follow up with a reminder email, maybe a discount code, and hopefully bring them back.
The problem is that GDPR considers this personal data processing. And under GDPR, you cannot process personal data for marketing purposes without a lawful basis to do so.
Many store owners assume that because someone started checkout on their site, they have implied permission to email them. That is not how GDPR works.
What Counts as Personal Data in Cart Tracking
You might think cart tracking is just “remembering what someone had in their cart.” But GDPR defines personal data broadly. In the context of abandoned cart recovery, personal data includes:
- Email addresses entered at checkout, even if the order was never completed
- Cart contents tied to an identifiable person, because knowing what someone almost bought is data about them
- IP addresses captured during the session
- Session data and cookies used to identify returning visitors
The moment you tie any of this data to an identifiable individual, GDPR applies. And if you are sending that data to a third-party service for email delivery, you are also dealing with data transfers, which adds another layer of compliance requirements.
What GDPR Actually Requires for Cart Tracking
GDPR does not ban cart tracking. It just requires you to do it properly. Here are the key requirements:
1. You Need a Lawful Basis
For marketing emails like cart recovery messages, consent is the safest lawful basis. Some businesses argue for “legitimate interest,” but this is riskier. Regulators have made it clear that marketing communications generally require explicit consent, especially when the person has not completed a purchase and does not have an existing customer relationship with you.
2. Consent Must Be Informed
A pre-ticked checkbox buried in your terms of service does not count. The customer must know, in plain language, what they are agreeing to. Something like: “We may email you a reminder if you don’t complete your purchase” is far better than three paragraphs of legalese.
3. Right to Erasure
Customers can request that you delete their data. This includes abandoned cart records. You need a process for handling these requests, and you need to be able to actually delete the data, not just hide it.
4. Data Minimization
Only collect what you need. If all you need for cart recovery is an email address and cart contents, do not also store browsing history, device fingerprints, and everything else you can get your hands on. Collect less, risk less.
How Most Cart Recovery Plugins Handle This (or Don’t)
Here is the uncomfortable truth: many WooCommerce cart recovery plugins use silent tracking with no consent mechanism at all. They capture the email address as soon as a customer types it into the checkout field, often using JavaScript to grab it in real time, and immediately start the abandonment timer.
No checkbox. No notification. No consent.
For customers outside the EU, this might be acceptable depending on local laws. But for EU customers, this approach is technically non-compliant. The fact that “everyone does it” does not make it legal.
Some plugins offer a consent checkbox as an optional add-on or premium feature. Others leave it entirely up to you to figure out. That is not ideal when the stakes include fines of up to 4% of annual global revenue.
How the Mautic Integration for WooCommerce Handles GDPR
When we built the abandoned cart tracking feature in the Mautic Integration for WooCommerce plugin, GDPR compliance was a core design consideration, not an afterthought. Here is how it works:
GDPR consent checkbox at checkout. The plugin adds a consent checkbox to the WooCommerce checkout page, enabled by default. The checkbox text is fully customizable, so you can write it in plain language that matches your brand voice. Customers see exactly what they are consenting to before any cart data is captured.
Cart data only captured with consent. When the consent checkbox is enabled, the plugin only records abandoned cart data for customers who actively check the box. No silent tracking behind their backs.
Silent capture option with clear warnings. For stores that operate outside the EU or have legal counsel advising a different approach, a silent capture option is available. But it is clearly labeled with guidance to ensure it complies with your local regulations. We do not hide this setting or make it the default.
Consent status recorded in the database. Every abandoned cart record includes a gdpr_consent field. This gives you an auditable trail showing whether consent was given, which matters if you ever need to demonstrate compliance.
The cron job respects consent. The automated process that checks for abandoned carts and triggers recovery emails skips any cart where the consent checkbox was displayed but not checked. This is not just a front-end check. It is enforced at the data processing level.
Your data stays on your server. Because the plugin works with self-hosted Mautic, all customer data, including cart details, email addresses, and consent records, stays on your own server. Nothing is sent to a third-party SaaS platform. You control where the data lives, how long it is kept, and who has access to it.

Best Practices for GDPR-Compliant Cart Tracking
Regardless of which plugin you use, these practices will help keep your cart tracking on the right side of GDPR:
Keep the Consent Checkbox Enabled for EU Customers
This is the simplest and safest approach. If you sell to customers in the EU, show the checkbox. If you only sell domestically outside the EU, check your local regulations, but the checkbox is still a good idea for building trust.
Use Plain Language
Do not write your consent text like a legal document. “We’ll send you a reminder email if you don’t complete your order” is clear and honest. Your customers will appreciate it, and clear language actually strengthens your consent under GDPR because the regulation specifically requires that consent be informed and unambiguous.
Update Your Privacy Policy
Add a section to your privacy policy that explains your cart tracking practices. Cover what data you collect, why you collect it, how long you keep it, and how customers can request deletion. This does not need to be long, but it does need to be there.
Set Up Data Retention
Do not keep abandoned cart data forever. Set a retention period and clean up old records. The Mautic Integration for WooCommerce plugin includes a daily cleanup cron that automatically removes expired cart data based on your configured retention window. Less old data sitting around means less risk.
Honor Deletion Requests Promptly
When a customer asks you to delete their data, do it. Under GDPR, you generally have 30 days to respond. Have a process in place so these requests do not fall through the cracks.
The Self-Hosting Advantage
One often overlooked benefit of using self-hosted Mautic for your cart recovery emails is the simplification of GDPR compliance around data transfers.
When you use a SaaS email marketing tool, your customer data is stored on their servers, often in a different country or jurisdiction. This can trigger GDPR requirements around international data transfers, data processing agreements, and ensuring the third party meets GDPR standards.
With self-hosted Mautic, you control the server. If your hosting is in the EU, your data stays in the EU. There is no third-party processor to vet, no cross-border transfer to justify, and no risk of a SaaS provider changing their data practices without your knowledge.
For stores that take data privacy seriously, this level of control is a significant advantage.
The Bottom Line
GDPR-compliant cart tracking for WooCommerce is not complicated, but it does require intentional choices. You need informed consent before capturing cart data for marketing. You need to record that consent. You need to respect it in your automated processes. And you need to give customers control over their data.
Most of this comes down to picking the right tools and configuring them properly. The Mautic Integration for WooCommerce plugin was built with these requirements in mind, so you can recover abandoned carts without cutting corners on privacy.
Your customers trust you with their data. That trust is worth more than any single recovered cart.
