Mailhook and Resend: Inbound Inquiry Auto-Reply with Reference Template
This Spojit template captures inbound support inquiries through a Mailhook, assigns each one a unique reference number, and sends a branded confirmation from your own domain with Resend.
What It Builds
A Mailhook trigger gives the workflow its own inbox address, and any message sent to it starts a run. A Connector node generates a unique reference number, then a Resend connector node sends a branded auto-reply from your verified domain confirming receipt and showing the reference so the customer immediately knows their inquiry landed.
The Prompt
Paste this into Miraxa and it builds the workflow, connecting the tools for you:
Build a workflow triggered by a Mailhook so customers can email our support inbox. For each incoming message, generate a unique reference number, then use Resend to send a branded auto-reply from support@ourdomain.com confirming we received their inquiry, echoing back their subject line, and showing the reference number they can quote in any follow-up.Connectors Used
- Mailhook - the trigger; gives the workflow a dedicated inbox address that starts a run on each inbound email.
- Resend - sends the branded auto-reply from your verified sending domain.
Customize It
Adjust the prompt to set your real sending address, change the reference format (for example a date prefix), or add fields like the customer name and a link to your help center. You can also tweak the subject line and reply copy to match your brand voice, all without writing a second prompt.
Tips
- Verify your sending domain in Resend first so replies pass authentication and avoid spam folders.
- Use the Resend node in Direct mode here: one exact send-email action, no AI cost.
- The reference number comes from the Mailhook run itself, so it stays stable across the customer's whole thread.
