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. Send emails from Shopify Flow workflows via API key or SMTP from your own domain Set a primary and backup provider — switches automatically if the primary fails See whether each email was delivered, bounced, or reported as spam Customize subject, preview text, and body with Liquid variables Send as your brand with a custom sender name, address, and reply-to Show more Show less
