Custom Email Domain

3 min readUpdated 2026-04-12

What Is a Custom Domain?

By default, your agent sends from a @leadclaw.io email address. With a custom domain (Ultra plan), your agent sends from your own domain — for example, outreach@yourbusiness.com.

Benefits

  • Better deliverability — Emails from your own domain build your domain's reputation
  • Professional branding — Recipients see your company domain, not a third-party service
  • Trust — Prospects are more likely to open emails from a recognizable domain
  • Consistency — Matches your website, business cards, and other marketing

Setup Process

  1. Go to Settings > Email > Custom Domain
  2. Enter your domain name (e.g., yourbusiness.com)
  3. LeadClaw provides DNS records you need to add:
    • SPF record — Authorizes LeadClaw to send on your behalf
    • DKIM record — Enables email signing for authenticity
    • DMARC record — Sets your email authentication policy
    • Add these records to your DNS provider (GoDaddy, Cloudflare, Namecheap, etc.)
    • Click Verify — LeadClaw checks your DNS records
    • Once verified, your agent starts sending from your custom domain

DNS Propagation

After adding DNS records, verification can take up to 48 hours for DNS propagation. Most domains verify within 1-4 hours.

Important Notes

  • Custom domain is available on the Ultra plan only
  • Your @leadclaw.io address continues to work as a fallback
  • Replies to your custom domain are still delivered to your agent automatically
  • You can switch back to @leadclaw.io at any time from Settings

Tip: If you already use your domain for regular email (e.g., Gmail/Google Workspace), the DNS records won't conflict — they're additive.
