Opt-in vs. Opt-out Consent: How to Choose the Right Model
No federal law covers customer consent for data collection and processing, so companies must comply with state-level regulations in the states where they operate.
There are two universal consent models around customer consent: opt-in and opt-out.
- With opt-in, you are allowed to process data only after the consumer provides their express written consent for it
- With opt-out, you are allowed to process data without obtaining consent and must stop doing it if the consumer opts out
Whether opt-in or opt-out applies depends mainly on the jurisdiction, applicable privacy laws, and the sensitivity of the collected data.
Non-compliance may lead to fines and a drop in consumer trust. At the same time, a transparent consent strategy prevents both – your business stays safe while lead quality goes up because every person on your list chose to be there.
Read on to learn how to design compliant, safe, and intuitive opt-in and opt-out processes.

Opt-in Consent & How It Works
Opt-in consent exists because global privacy laws require personal data to remain untouched until the consumer explicitly permits its use. Under both the U.S. TCPA and Europe’s GDPR, user consent must be freely given, informed, specific, and unambiguous.
For example, a signup form with an unchecked box, a cookie banner waiting for a click, or a mobile app that asks for consent before tracking anything are all legitimate ways to get an opt-in before you start processing consumer data. In addition, consumers who opt in voluntarily open more emails, click more links, and stay on your list longer.
Opt-out Consent & How It Works
In contrast, the opt-out consent framework allows you to collect and process consumer data by default until the consumer asks otherwise. U.S. privacy statutes like the CCPA/CPRA, the VCDPA, and the CAN-SPAM Act are built around the opt-out marketing model for general data processing and targeted advertising.
For example, an “unsubscribe” link at the bottom of a marketing email and a “do not sell or share my personal information” link on a website are opt-out consent mechanisms that allow consumers to withdraw consent with one click.
Opt-in vs. Opt-out Consent Models
| Feature | Opt-in Consent | Opt-out Consent |
| Default state | Data collection is disabled by default | Data collection is enabled by default |
| User action | Prior express written consent is required so a business can start collecting and processing consumer data | Opt-out request is required so a business stops collecting and processing consumer data |
| Primary regulations | GDPR (EU/UK), TCPA (US) | CCPA/CPRA, CAN-SPAM |
| Examples | Cookie banner acceptance, SMS subscription forms | Email unsubscribe links, “Do not sell my info” footer links |
Real-World Opt-in & Opt-out Examples
Both opt-in and opt-out consent models apply across various marketing and data processing channels:
- Email marketing: Under the GDPR, promotional newsletters require users to actively opt in before anything is sent. In addition, every marketing email needs a functional unsubscribe link (opt-out) for CAN-SPAM and global privacy compliance.
- Website cookies: California and Europe handle this differently. California allows cookies to load by default, but only if the website includes a visible opt-out link. European visitors won’t get non-essential analytics or advertising cookies until they opt in by clicking “accept” on a cookie banner.
- Lead generation and SMS campaigns: Cold calling or sending promotional text messages in the United States requires prior express written opt-in consent under the TCPA. Recipients must also be able to opt out at any time.
“Obviously, you need opt-in consent to send text messages properly, but assuming you have all of that, I think email is a great channel. People sometimes respond to that more easily than to a phone call. I think using all of your channels is super important, but I think it should always be driving towards that phone call.” – Chaz Tedesco, Chief Operating Officer at CallTools, from the Mastering the Lead-to-Sale Journey with Intelligent Call Campaigns webinar.
Building a Compliant & Transparent Consent Management Strategy
The opt-in vs. opt-out decision depends on where your business operates, what personal information you collect, and what laws like the GDPR or CCPA require. Whichever model applies, consent requests must be clear and accessible so consumers understand how their data is collected and used.
There’s a business case too – consumers who share personal data voluntarily make better prospects. Likewise, when consumers can opt out easily through a clear unsubscribe path, spam complaints drop and domain reputation stays consistent across all marketing channels.
Last but not least, proof of user consent – when they opted in and opted out – has to be verifiable and stored properly. By collecting and storing user consent, you protect your business from potential claims and can pass compliance audits.

Frequently Asked Questions
Opt-in vs. opt-out consent: what’s the main difference?
Data collection and marketing don’t begin under opt-in until the consumer chooses to opt in. Opt-out doesn’t wait for that. The business is already collecting and processing data, and a customer who wants it stopped has to opt out or unsubscribe.
What does it mean to opt in and opt out under GDPR versus CCPA?
Under the GDPR, businesses in the European Union must get opt-in consent before collecting non-essential personal data or cookies. No agreement from the user, no processing. California’s CCPA defaults to the opposite. General data processing is allowed, and residents hold the right to opt out of the sale or sharing of their personal information.
What is an example of an opt-out option on a website?
Most websites place a “do not sell or share my personal information” link in the footer. A visitor clicks it to opt out of the sale or sharing of their data and adjust privacy preferences.
Why is explicit opt-in consent required for sensitive data?
Privacy laws treat sensitive personal information – health records, financial data, biometrics, data from minors – as higher risk. Explicit opt-in makes sure consumers know exactly how their sensitive data will be handled before any processing starts.
Can customers opt out after they opt in?
Yes, and this isn’t optional. The GDPR, TCPA, and CAN-SPAM all guarantee it. A consumer who opted in can withdraw that consent whenever they want, and doing so must be as easy as signing up was.
