Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureShopify Flow's built-in email can't send to a customer's address. FlowPost adds a Send transactional email action to Flow, so you can email customers, staff or suppliers when anything happens: order tagged, COD order, B2B approval, low stock or fraud risk. Send from your own domain through SMTP, Gmail, Microsoft 365, Amazon SES, Resend, SendGrid, Mailgun or Postmark.
FlowSend lets you send fully branded transactional emails directly from Shopify Flow using your own SMTP provider or website domain. Send internal email action for workflow with flow, instead of shopifyemail.com Instead of relying on basic notifications, you can trigger custom emails for orders, B2B workflow, internal alerts, approvals, fraud checks, or any automation you build inside Flow.
- Send transactional email from Shopify Flow workflows
- Connect SMTP or providers like SES, Resend, SendGrid, and Mailgun
- Optional fallback routing when the primary provider fails
- Templates and sent-email logs for day-to-day operations
- Use FlowSend to send emails directly from Shopify Flow workflows
- Connect your own SMTP provider securely
- Create dynamic templates using Liquid variables
- Add CC, BCC, and custom Reply To addresses
