About FlowRelay: Send Email via Flow
FlowRelay adds the Send transactional email action to Shopify Flow. Email content is customizable using Liquid variables — pull in order details, customer names, or any attribute from your workflow. Emails go out through your own provider (such as SendGrid, Resend, Mailgun, or Postmark) and domain via API key or SMTP. Delivery status is recorded for each email: delivered, bounced, or reported as spam. Use it for order confirmations, account notifications, internal alerts, or any custom email.
