Should Shopify checkout opt-in boxes for email marketing be pre-checked for GDPR and deliverability?

Summary

The question of whether Shopify checkout opt-in boxes for email marketing should be pre-checked is a complex one, balancing legal compliance, user experience, and email deliverability. While pre-checked boxes might seem appealing for maximizing subscriber acquisition, they directly conflict with GDPR requirements for explicit consent. Shopify's system adds a layer of complexity, as it may unsubscribe previously opted-in customers if they leave the marketing checkbox unchecked during checkout, viewing this as a re-confirmation of their marketing preference.Understanding the impact of GDPR on email marketing is crucial here. The prevailing expert and documentation opinion firmly states that consent must be an active, affirmative action, rendering pre-checked boxes non-compliant in many jurisdictions, particularly under GDPR and CASL. This stance is primarily driven by the need to protect consumer privacy and ensure genuine interest in receiving communications. On the other hand, some marketers prioritize growth and higher subscriber numbers, arguing that an easy unsubscribe option mitigates the risk of negative engagement or legal issues.The core dilemma lies in navigating these differing priorities. While Shopify's recommendation to pre-check might retain more existing subscribers, it introduces significant legal and deliverability risks, as recipients who did not explicitly opt in are more likely to mark emails as spam, leading to a damaged sender reputation or even blocklist appearances. For optimal email deliverability and legal compliance, the consensus leans heavily towards un-checked boxes and transparent consent collection methods.

What email marketers say

Email marketers have diverse perspectives on pre-checked opt-in boxes, often weighing subscriber acquisition against compliance. Some prefer pre-checked boxes, reasoning that customers who just made a purchase might expect marketing emails and can easily unsubscribe if not interested. They tend to prioritize list growth, believing that the convenience for the customer outweighs strict adherence to opt-in principles for deliverability purposes. However, many marketers acknowledge the legal obligations, especially concerning GDPR, which explicitly prohibits pre-checked boxes for consent. This creates a tension between business objectives and regulatory compliance.The behavior of Shopify's checkout process further complicates matters for marketers. When a customer, even one who was previously subscribed, leaves the marketing checkbox unchecked during checkout, Shopify's system automatically opts them out. This unexpected behavior can lead to a loss of existing subscribers, which is a significant concern for marketers focused on retention. Consequently, marketers are often caught between Shopify's default settings, their desire for list growth, and the imperative to maintain a healthy sender reputation and avoid blocklists.

Marketer view

Marketer from Email Geeks explains that they just had a conversation with a client earlier this month and they decided to go with Shopify’s recommendation of having the opt-in box pre-checked. Their argument was that customers who have just made a purchase would not be surprised to receive marketing emails from the company. Furthermore, they made sure that if customers overlooked the checkbox or did not want any further emails, it would be very easy for them to unsubscribe.

Marketer view

Marketer from Email Geeks notes that they are the type of person who would not check the box, or would un-check it, if they already receive emails from that brand. They assume they do not need to re-check the box to continue receiving emails, highlighting a potential misunderstanding between system behavior and user expectation.

What the experts say

Deliverability experts generally hold a firm stance that explicit consent is paramount, prioritizing legal compliance and long-term sender reputation over short-term subscriber gains. They advise against pre-checked boxes, especially in regions with strict data protection laws like GDPR, CASL, and TCPA. The core argument is that true consent requires an affirmative, unprompted action from the user, not a passive default.Experts also highlight the potential negative consequences of using pre-checked boxes, such as increased spam complaints, lower engagement rates, and the risk of being placed on blocklists. While transactional emails to recent customers often have good engagement, extending this to marketing emails without explicit consent can lead to poor deliverability outcomes. The legal ramifications, including potential fines and reputational damage, are also a significant concern. Ultimately, experts emphasize that a clean, engaged list built on explicit consent is more valuable for sustained deliverability than a larger list with questionable opt-in practices.

Expert view

Expert from Email Geeks explains that Shopify has exhibited this behavior for years, stating they recall dealing with it during their time at Bronto. They emphasize that regardless of Shopify's internal decisions, the question remains whether leaving the box unchecked is the legally responsible choice, especially if collecting subscribers from outside the US, where consent laws are stricter.

Expert view

Expert from Email Geeks asserts that leaving the box checked is an assumption of permission, not a granting of permission. They highlight that it represents the default assumption that a company gets to send emails. In some cases, this means actual permission is lacking, potentially leading to complaints or negative signals that impact deliverability.

What the documentation says

Official documentation and privacy regulations, particularly GDPR (General Data Protection Regulation), are unequivocal about consent requirements. They universally prohibit the use of pre-checked boxes for obtaining marketing consent. GDPR specifies that consent must be freely given, specific, informed and unambiguous, requiring a clear affirmative action. This means the user must actively opt in, not just fail to opt out.Documentation also frequently recommends, though does not always strictly mandate, double opt-in as a best practice to provide stronger proof of consent. This extra step helps verify that the email address belongs to the person who signed up and that they genuinely want to receive communications. Furthermore, regulations emphasize the importance of clear, jargon-free disclosure language and easily accessible methods for users to withdraw their consent at any time. Adhering to these documented principles is not just about compliance, but also about building a high-quality, engaged audience that benefits overall deliverability and sender reputation.
