How do I comply with GDPR when running Mother's Day email campaigns to EU customers?

GDPR requires explicit prior consent for marketing emails sent to EU residents, which is more restrictive than US CAN-SPAM rules. If your Shopify store has European customers on your email list, you need to understand what compliance requires before sending your Mother's Day campaign.

The short answer

Under GDPR, you can only send Mother's Day marketing emails to EU subscribers who have given explicit prior consent to receive marketing communications from your store. Implied consent (purchasing from your store) is not sufficient. Before your campaign launches, audit your EU subscriber list in Klaviyo or Mailchimp for consent status and remove any contacts without a documented opt-in. Sending Mother's Day emails to non-consenting EU subscribers risks fines of up to 4% of global annual turnover or 20 million euros, whichever is higher.

In depth

GDPR Compliance for Mother's Day Email Campaigns

GDPR applies to any business processing personal data of EU residents, regardless of where the business is located. If your Shopify store ships to the EU or has EU subscribers on your email list, GDPR affects your Mother's Day campaign. The key requirement is that marketing emails require prior explicit consent - a purchase alone does not provide this consent.

GDPR vs. CAN-SPAM: Key Differences

Consent modelOpt-in required (explicit prior consent)Opt-out model (can send until opt-out)
Purchase as consentNOT sufficientExisting relationship permitted
Consent documentationMust be recorded and provableNot required
Maximum penalty4% of global turnover or 20M euros$51,744 per email

Pre-Campaign GDPR Audit Steps

  • Filter by country - In Klaviyo or Mailchimp, filter your Mother's Day send list to EU countries (Germany, France, Netherlands, etc.) and verify each segment has documented opt-in consent
  • Check consent source - Contacts added via a newsletter opt-in form have valid consent; contacts added via order import or list upload without consent records do not
  • Suppress non-consenting contacts - Create a suppression list for EU contacts without documented consent before sending; this protects you legally and improves your deliverability by removing unengaged contacts

Going Forward

After your Mother's Day campaign, update your Shopify checkout to include a clearly labeled, unchecked marketing consent checkbox for EU customers. This is the standard way to build a GDPR-compliant EU email list. Contacts collected this way have documented, dated consent and can legally receive future campaigns including next year's Mother's Day promotions.
