Set Up Replies in Mailgun

Prerequisite: Paid Mailgun Plan

Reply routing requires a paid Mailgun plan (at least the Foundation plan). If you’re on a free plan, inbound routing features may not be available.

Step 1: Create a Receiving Route

The receiving route tells Mailgun what to do with inbound replies. For BizStackPro, you’ll forward inbound mail to the webhook endpoint.

1. In Mailgun, open the Receiving tab.
2. Click Create Route (top right).
3. Set Expression Type to Catch All.
4. Enable Forward and paste: https://msgsndr.com/mailgun/inbound_webhook
5. Set Priority to 99.
6. (Optional) Add a description like MG Receiving Route.
7. Click Create Route to save.

Step 2: Confirm the Route Was Created

After saving, you should see a route similar to this in your list:

catch_all() Priority: 99
forward("https://msgsndr.com/mailgun/inbound_webhook")

Important: WIX Limitation (MX Records)

Reply routing typically depends on inbound email delivery to Mailgun, which requires MX records. Some providers (like WIX in certain configurations) don’t allow full MX record control.

1. Move DNS management to Cloudflare (or another DNS provider that supports MX records).
2. Add the required MX records and Mailgun DNS records for your sending/replies domain.
3. Verify DNS in Mailgun after the records propagate.

Pro Tips

• Test after setup: Send a reply to a recent outbound email and confirm it appears in BizStackPro.
• Confirm MX records: Inbound routing won’t work without the correct MX records.
• Label routes clearly: Helpful when you manage multiple domains or environments.
• Monitor inbound logs: Use Mailgun’s inbound logs to confirm forwarding activity.
