What is cookie consent management in email?

Email and cookies don't obviously go together. But they intersect in a few specific ways that are worth understanding, especially if you're sending to EU subscribers.

The most common intersection: tracking pixels. Email open tracking works by embedding a tiny invisible image in your email. When the recipient's email client loads that image, it records the open event along with the recipient's IP address, device type, and timestamp. Under GDPR, there's a genuine debate about whether this constitutes cookie-like tracking that requires consent. Some EU data protection authorities have indicated it does. Most email senders don't seek explicit consent for pixel tracking, but the legal risk isn't zero.

The clearer situation is what happens when someone clicks a link in your email and lands on your website. At that point, the website's cookie consent rules kick in. If your site uses a Consent Management Platform, the subscriber sees the cookie banner. That's a separate consent event from their email subscription consent. Your preference center (where subscribers manage email preferences) uses cookies too, which need to be handled correctly if it's web-based.

Practically, this means you need two things to be consistent. First, your email consent records should note whether the subscriber was informed about tracking pixels at sign-up. Second, your website's cookie consent should integrate with your email preference center so that "unsubscribe from everything" actually works across both.
