Some countries, including Germany, Austria, Switzerland, and others in the EU, require or strongly recommend double opt-in for email marketing. Even where not required (like the US or Canada), double opt-in helps you maintain list quality, reduce spam complaints, and improve legal compliance.
To maximize deliverability and build trust with your subscribers, we recommend enabling double opt-in in your Shopify admin alongside setting up a custom email domain for Growave notifications.
How to enable double opt-in in Shopify
To activate double opt-in for marketing emails:
Go to your Shopify admin → Settings (bottom left corner).
Click Notifications → Customer notifications section.
Scroll to the Marketing double opt-in, enable Customer marketing confirmation toggle. This will send a confirmation email to customers who sign up for your marketing list — they must click a link to confirm their subscription.
Optional but recommended
Customize the confirmation email
Still in Shopify Settings → Notifications, scroll to Customer marketing confirmation, click > (right arrow) button → Edit code.
Make sure the confirmation email is clear, neutral, and does not contain marketing content, as required in some jurisdictions.
Update your newsletter form's confirmation message
Go to Online Store → Themes.
Click the three dots menu button on your live theme and select Edit default theme content.
Search for the Newsletter tab and edit text to say something like:
“Please check your inbox to confirm your subscription.”
