Setting up a dedicated email domain is critical for email marketing success. A dedicated subdomain separates your marketing and automation traffic from your regular email — protecting your main domain’s reputation and ensuring campaigns actually reach inboxes.
Dedicated email domain for email messaging

​
Why this matters

If you send marketing emails from your main business domain and one campaign generates high spam reports or bounces, your entire domain reputation can suffer — affecting even regular business email delivery. A dedicated sending subdomain isolates this risk completely.
You must add a DMARC record to your DNS settings. Copy and paste the following exactly, with no leading or trailing spaces:
  • Record Type: TXT
  • Host/Name: _DMARC
  • Content/Points to field: v=DMARC1; p=none;

​
How to set up your dedicated email domain

1

Navigate to Email Services

Go to Settings > Email Services (or Email > Dedicated Sending Domain depending on your account view).

2

Choose a subdomain

Decide on a subdomain for your marketing emails. Common examples:
  • mail.yourbusiness.com
  • send.yourbusiness.com
  • marketing.yourbusiness.com
Using a subdomain rather than your root domain protects your main domain’s reputation if a campaign has deliverability issues.
3

Add the domain in the platform

Enter your chosen subdomain and click Add Domain. The platform will generate the DNS records you need to add at your registrar.

4

Add DNS records at your registrar

Log in to your domain registrar (GoDaddy, Namecheap, Cloudflare, etc.) and add each DNS record the platform provides — typically CNAME and TXT records for DKIM verification.Add each record exactly as shown. Spacing and punctuation matter.
5

Add your DMARC record

In your registrar’s DNS management panel, add a new TXT record:
  • Host/Name: _DMARC
  • Value: v=DMARC1; p=none;

6

Verify the domain

Return to the HoopAI Platform and click Verify. DNS propagation can take up to 24–48 hours. Once verified, your domain status shows as active and ready to use for email sending.
If verification fails immediately, wait a few hours before trying again. DNS propagation times vary by registrar and region.

​
Key points

If a marketing campaign generates high spam complaints or bounces, your sending subdomain takes the hit — not your main domain. Your regular business email remains unaffected.
Typically: DKIM CNAME records (generated by the platform), an SPF TXT record, and a DMARC TXT record. The platform generates your DKIM values automatically — you must manually add the DMARC record.
DNS changes propagate globally within a few hours to 48 hours. If verification fails immediately, wait and check again before contacting support.

Key benefits

Dedicated domain emails land in inboxes more reliably than emails sent from shared or main domains.
A custom sending domain reinforces your brand identity in every email you send.
Track marketing email performance separately from your regular business email.
Properly authenticated emails signal to email providers that your messages are legitimate.
Higher deliverability means more opens, clicks, and conversions from every campaign.
