Email non subscribed customers through Flow

Topic summary

Automating emails to event registrants who are not subscribed to marketing via Shopify Flow. The goal is to send an automatic email after form registration, regardless of marketing opt-in.

Key update: The “Send Marketing Email” action in Shopify Flow only delivers to customers who have explicitly subscribed to marketing emails; sending to non-subscribers is treated as spam under Shopify’s policies.

Evidence: Screenshots show a Flow setup and results returning negative. The reply clarifies the limitation is by design, not a Flow misconfiguration.

References: Shopify documentation on marketing automations and subscriber list management was provided for consent requirements and best practices.

Outcome: The requested behavior (emailing non-subscribers via “Send Marketing Email”) is not supported. To proceed, customers must opt in to marketing before they can be emailed via this action.

Status: Clarified limitation; no alternative or workaround was proposed. Discussion effectively resolved on capability constraints.

Hi TBS2023, the Send Marketing Email action can only send to customers that have subscribed to marketing emails, else it’s spam.
