- Short answer
- Shopify said in December 2023 that one-click unsubscribe was already met through its infrastructure, so no action on it was needed from you.
- Custom Liquid emails
- Must include unsubscribe_link or unsubscribe_url; both point to your primary store domain
- After a subscriber unsubscribes
- Removed from your subscriber list and automatically excluded from future campaigns
- Who Google's rule covers
- Senders of more than 5,000 messages a day to Gmail accounts
- Don't judge by a test email
- Our October 2026 test email carried a suppression-bypass header; check a real campaign email instead
Is there a List-Unsubscribe header in Messaging emails?
In a December 21, 2023 Shopify Community announcement, before Shopify Email became Messaging, Shopify staff wrote: “The other requirements stated by Gmail and Yahoo have already been met through Shopify’s infrastructure (such as a one-click-unsubscribe), so no other actions are required from you.”
That announcement doesn't name a List-Unsubscribe header or RFC 8058, and neither do the Help Center's Messaging pages or the Shopify and shopify.dev changelogs we read in October 2026; none describes a setting for it.
Don't check with Send test: our test from a development store on October 29, 2026 carried a suppression-bypass header and a preview unsubscribe link, and had no List-Unsubscribe header. Its missing header proves nothing about campaigns. Subscribe your own address, receive a real campaign, and in Gmail's Show original look for List-Unsubscribe and List-Unsubscribe-Post.
What Shopify documents about the unsubscribe link
- Clicking Unsubscribe, marking an email as spam or opting out in their account removes subscribers from your list.
- Unsubscribed customers are automatically excluded from future campaigns.
- Custom Liquid emails require the
unsubscribe_linkorunsubscribe_urlvariable, which always points to your primary store domain; the raw URL can be customized but not redirected elsewhere.
In branded templates (not custom Liquid), none of the Messaging pages we read says you can remove the link or change its text or URL.
What Gmail and Yahoo require, and what stays with you
Mailbox providers set the rule, phased in from February 2024. Google's covers senders of more than 5,000 messages a day to Gmail accounts:
Marketing messages and subscribed messages must support one-click unsubscribe, and include a clearly visible unsubscribe link in the message body.
Gmail wants List-Unsubscribe-Post plus a List-Unsubscribe URL and exempts transactional messages. Yahoo calls the Post method (RFC 8058) “highly recommended” and says requests should be processed within 2 days.
Shopify's deliverability help says sending from its authenticated shopifyemail.com subdomain meets the authentication requirements Gmail and Yahoo set for bulk senders. Authenticating your own sending domain is optional but recommended: which DNS records Shopify Messaging needs.
Both providers also set spam-rate limits; see our Gmail and Yahoo deliverability section.
