How to use your primary domain for outbound email

How to use your primary domain for outbound email

You can host your funnel on a subdomain like go.client.com and still send outbound email from your main domain like hello@client.com.

RevMozi now treats these as two separate jobs:

• Website domain controls where your funnel is hosted
• Outbound email domain controls the From address used for email sending

That separation matters because many businesses already have a main website and working inboxes on the root domain, but still want branded outbound email from that same root domain.

When to use this setup

Use this setup when:

• Your website or funnel is hosted on a subdomain such as go.client.com
• Your company email already works on the main domain such as client.com
• You want RevMozi to send from an address like hello@client.com

Steps

1. Connect your funnel website domain the normal way. Example: go.client.com
2. Open the Outbound Email Domain card in the domain settings screen.
3. Add your main domain. Example: client.com
4. Copy the DNS records RevMozi shows and add them at your registrar or DNS provider.
5. Wait for DNS propagation, then click Check Verification.
6. After verification, choose the From name and From address prefix you want to use.

DNS records to expect

RevMozi shows the exact records returned by Resend for your domain. In most cases you will see records like these:

• send.client.com as an MX record for the return path
• send.client.com as a TXT record for SPF
• resend._domainkey.client.com as a DKIM record
• A tracking CNAME if tracking is enabled for that domain

The exact values can vary by provider configuration. Use the values shown in RevMozi as the source of truth.

What does not change

• Your existing inbox provider MX records for client.com stay in place
• Your website can keep running on go.client.com
• Your existing DMARC policy should stay as-is unless you intentionally update it

This works because Resend’s return-path records are usually added on a subdomain such as send.client.com, not by replacing the root-domain mailbox MX records.

Important notes

• If you already have a DMARC record on the root domain, do not overwrite it.
• If your DNS provider asks for a host instead of a full hostname, enter only the host part shown in the UI.
• For cold outreach or high-volume prospecting, do not use your primary business domain. Use a separate outreach domain instead to protect deliverability for support, invoices, and normal business email.
