How to Connect Your Own Custom Domain to Email Generator

Connecting a domain you own gives you a clean, unshared namespace for temporary testing and per-website addresses. Setting it up requires only a standard DNS MX record at your domain registrar—never share your registrar login or password with anyone.

Step-by-Step Custom Domain Setup

1. Register a domain: Purchase any domain name you control from an ICANN-accredited registrar (such as Cloudflare, Namecheap, Porkbun, or GoDaddy).
2. Add an MX record in your DNS panel: Point the root (@) of your domain (or a dedicated subdomain like mailtemp.yourdomain.com) to our mail host with priority 10. Need help finding the DNS screen? Follow How to Add an MX Record.
3. Submit the domain on Email Generator: Click the Add Domain button in the top navigation bar on Email Generator, enter your domain name, and submit your request for admin verification.
4. Verify DNS propagation: Use our Disposable Email Domain Checker or read How to Check Your Domain to confirm your new MX record is live worldwide.

Benefits of Using Your Own Domain

• Fresh Domain Reputation: Unlike heavily shared public domains, a domain you control is not pre-listed on public disposable-domain blocklists.
• Unlimited On-Demand Local-Parts: Pair your domain with a separate email address for every website ([email protected], [email protected]).
• Full DNS Ownership: Because routing is controlled by a single MX line in your own registrar panel, you can redirect or disconnect your domain whenever you choose.

Important Security Notes

• Receive-Only Utility: Custom domains connected to Email Generator are designed for receiving confirmations, codes, and QA test messages, not sending outbound emails.
• Access Controls: Public domains allow open inbox viewing by address, while custom usernames with a Buyer Access Code and dedicated sub-admin workspaces provide isolated domain management. Review our Privacy Policy and Contact page if you need dedicated sub-admin domain onboarding.
