Working with Subdomains

Learn how subdomains work in MelMe and when you should use them instead of your root domain.

1. Overview

A Subdomain is a prefix added to your main domain name. For example, if your main domain is mycompany.com, a subdomain could be mail.mycompany.com, contact.mycompany.com, or tickets.mycompany.com. MelMe has complete support for subdomains, allowing you to create custom aliases under these specific prefixes.

2. Why This Matters

Using subdomains is highly beneficial for several reasons:

Separation of Concerns: You can keep your primary root domain inbox (e.g. ceo@mycompany.com on Google Workspace) intact, while utilizing MelMe on a subdomain (e.g. support@mail.mycompany.com) for handling high-volume customer queries or marketing letters.
Isolating Spam Risks: If a subdomain gets flagged by spam filters, your primary root domain's email deliverability remains protected.
Organizational Clarity: Create separate subdomains for different products, departments, or campaigns.

3. How to Use It

Step 1: Add the Subdomain in MelMe

Open the Domains tab and click Add Domain.
Type in your subdomain (e.g., help.yourdomain.com).
Click Submit.

Step 2: Configure DNS Settings

Adding a subdomain requires pointing DNS records specifically for that subdomain:

MX Record: Instead of setting the host/name to @, set the host/name to your subdomain prefix (e.g., help). Enter the MX server address and set priority to 10.
TXT & DKIM CNAME Records: Copy and paste the specific subdomain host values generated by MelMe into your DNS settings.
Verify: Once added, click Verify in the dashboard.

4. Common Mistakes

Typing the full subdomain in the DNS Host field twice: If you are adding records for help.yourdomain.com in GoDaddy, and the GoDaddy Host field already automatically appends yourdomain.com, you should only enter help in the Host field, not help.yourdomain.com.
Assuming subdomains share root domain DNS records: Subdomains must have their own unique DNS records. Creating MX records on your root domain will not route emails sent to your subdomain.

5. Tips

Recommended Setup: If you are launching a newsletter or cold outreach campaign, always use a subdomain (e.g., news.mybrand.com) to protect your root domain's reputation.
