Shopify Flow - Email Sent To Customer if Order contains a tag

Topic summary

Goal: set up a Shopify Flow that sends an email to a customer when an order contains a specific tag and the order is updated.

Current capabilities:

  • Flow includes an “internal email” task (for notifying staff) and, in Marketing > Automations, a “Send Marketing Email” task (for promotional emails).
  • There is no native “Send Transactional Email” task (transactional = order/account-related messages triggered by events).

Workarounds suggested:

  • Use a third‑party (3p) app/task that supports transactional emails and integrates with Flow.
  • Or call an external email service from Flow using the “Send HTTP Request” action (i.e., post to an API of your email provider to send the message).

Participant perspectives:

  • Merchants want Flow to natively send a custom Shopify email when an order is tagged, triggering the message.
  • Shopify’s response: this capability is not available natively; rely on 3p solutions or HTTP requests for now.

Status:

  • No resolution or timeline for native transactional emails in Flow. Actionable path today is to implement a 3p email service or app via Flow’s HTTP request.

Hi we are finding our way around Shopify Flow and would like help with setting up a workflow

Send email to customer if order contains tag when order updated.

For the email, currently the built-in functionality for Flow has a “internal email” task. In the editor for Marketing > Automations, we also offer a “Send Marketing Email” task. There is not yet a “Send Transactional Email” task, if that is your goal. Some of our 3p tasks do provide the ability to send transaction email, so if that is your aim, you’ll have to use those for now. You could also use your own 3p service, coupled with the Send HTTP Request action.

Dear Shopify Team, is there a solution for transactional Emails in the meantime?

You would need to use a 3p app or service. Some of them work with Flow or you can call them from Flow using Send HTTP Request.

I am also interested in this functionality - Flow should be able to send a custom Shopify email after tagging the order with a specific tag.
