Custom domain temp mail is the most powerful form of disposable email — use your own domain to receive temp mail, bypassing blocklists while protecting privacy. This guide shows you how.
What Is Custom Domain Temp Mail
Standard temp mail uses the service's domains (like 215.im, guerrillamail.com) which are easily blocklisted. Custom domain temp mail uses your own domain (like mail@yourbrand.com) — the target site sees a normal domain and can't tell it's temporary.
This is YYDS Mail's core differentiator — most free temp mail services don't support custom domains.

Setup Steps
Step 1: Get a Domain

Step 3: Configure DNS
In your domain's DNS management:

Specific values shown in the console after adding. DNS propagation: minutes to hours.
Step 4: Verify and Use
After DNS propagates, click "Verify" in the console. Once verified, you can receive mail at anything@yourdomain.com.
