Custom Email Domains

Why use a custom domain?

• Professional appearance - emails come from your agency domain, not a generic one

• Better deliverability - properly configured domains improve inbox placement

• Brand consistency - recipients see your brand in the "From" address

• Trust - clients are more likely to open emails from a domain they recognise

Setting up a custom domain

Prerequisites

• A domain you own (e.g. youragency.com)

• Access to your domain's DNS settings

Steps

1. Go to Workspace Settings

2. Navigate to the Email section

3. Click Add Custom Domain

4. Enter your domain name

5. Market Trak will provide you with DNS records to add:

   • TXT records for SPF and DKIM verification

   • CNAME record for Mailgun tracking

6. Add these records in your domain's DNS management panel

7. Wait for DNS propagation (usually a few minutes, sometimes up to 48 hours)

8. Click Verify in Market Trak to confirm the records are in place

Once verified, your campaigns will be sent from your custom domain.

DNS records explained

These records do not affect your existing email or website. They only authorise Mailgun to send on your behalf.

Sending behaviour

After connecting a custom domain:

• Campaign emails - sent via Mailgun from your domain

• Welcome emails - sent via Mailgun from your domain

• System emails (verifications) - continue to be sent from Market Trak's system address

Rate limits

Custom domains via Mailgun support higher sending rates:

• Mailgun: up to 1,000 emails per batch

This means campaigns go out faster with a custom domain.

Troubleshooting

Domain not verifying

• Double-check DNS records are entered exactly as shown (including the trailing period on some providers)

• Wait for DNS propagation, it can take up to 48 hours

• Ensure your domain registrar does not strip or modify TXT records

Emails going to spam

• Verify your SPF and DKIM records are correctly configured

• Build sender reputation gradually, start with small campaigns

• Ensure your email content is not overly promotional or flagged by spam filters

Tips

• Use a subdomain like mail.youragency.com or updates.youragency.com to separate marketing emails from your regular business email

• Check your domain verification status periodically in Workspace Settings

• A properly configured custom domain significantly improves email deliverability
