Questions from Amsterdam stores
Should my default language be Dutch or English?
Look at who buys. If you are unsure, default to Dutch and let people switch to English at signup.
Do the Dutch consent rules apply to English-speaking customers?
Yes. You are a Dutch store, so the same GDPR and ePrivacy rules apply, whatever language the customer reads.
Can I see which language earns more?
Yes. Reports show revenue per email, so compare the Dutch and English version of the same campaign.
