Definition
A consent banner, sometimes called a cookie or privacy banner, is a notice displayed on a website that informs visitors about data collection practices and, in email marketing contexts, collects permission to send marketing messages. It is a common mechanism for demonstrating compliance with privacy regulations like GDPR, CCPA and PECR.
For email marketers, the consent banner is the first step in the subscriber relationship. A well-designed banner explains what the visitor is signing up for, how often emails will be sent and what value they will receive. It should not use deceptive design, pre-ticked boxes or unclear language.
The banner should connect to the email platform so that consent records are stored, timestamped and linked to the subscriber profile. This creates an audit trail that is valuable if a compliance question arises later.
Best Practices
- Use clear, plain language that explains what the subscriber will receive.
- Avoid pre-ticked boxes or dark patterns that trick users into consenting.
- Separate email marketing consent from other permissions, such as cookies or analytics.
- Store the consent record, timestamp, source and IP address for compliance.
- Make it easy to withdraw consent through unsubscribe links and preference centres.

Frequently Asked Questions
In many jurisdictions, yes. GDPR, CCPA and similar laws require transparency about data collection and consent for marketing emails.

No. Under GDPR, consent must be freely given, specific, informed and unambiguous. Pre-ticked boxes do not meet this standard.
Keep consent records as long as the subscriber is on your list and for a reasonable period after, in case of a compliance audit.
