Custom Domain Configuration

Custom domain setup routes email from support@yourcompany.com (or any address on your domain) into Ticket0 without any third-party forwarding. It's the recommended approach for production use.

Prerequisites

• A domain you control with access to DNS records
• A Resend account (free tier is fine)

Step 1 — Verify your domain in Resend

1. Log in to Resend and go to Domains → Add domain
2. Enter your domain (e.g. yourcompany.com)
3. Add the DNS records shown:
   • MX record for inbound routing
   • TXT record for ownership verification

DNS changes typically propagate within 5–30 minutes.

Step 2 — Add SPF and DKIM records

To ensure outbound replies sent by Ticket0 pass email authentication:

1. In Resend, go to Domains → [your domain] → DNS records
2. Add the SPF and DKIM records shown

See SPF and DKIM verification for the exact records and how to verify them.

Step 3 — Create an inbox in Ticket0

1. Go to Settings → Inboxes → New inbox
2. Choose Custom domain
3. Enter your verified domain and the local part (e.g. support for support@yourcompany.com)
4. Click Create — a webhook URL is generated

Step 4 — Create an inbound route in Resend

1. In Resend, go to Email → Inbound → Add route
2. Set the match pattern: support@yourcompany.com
3. Set the destination: the webhook URL from step 3
4. Save

Step 5 — Test

Send a test email to support@yourcompany.com. It should appear as a ticket within a few seconds.
