How many domains does Tmailor have?
More than 500 domains.
Quick access
One of the most powerful features of tmailor.com is its extensive domain pool for temporary emails. As of 2025, tmailor.com operates with over 500 rotating domains — one of the largest offerings among disposable email services.
🧩 Why does domain variety matter?
Many websites actively blacklist or detect temporary email domains. When a service only offers 1–5 domain names, its users are easily flagged and blocked. But with tmailor.com's 500+ domains, your email address is more likely to bypass these filters, making it more reliable for:
- Verifying social media or SaaS accounts
- Receiving OTP codes
- Accessing gated content or downloads
This large domain base is hosted on Google's infrastructure, which improves delivery speed and adds trust signals to recipient servers.
🚀 Where to view or use these domains
When you generate a temporary inbox at tmailor.com, the system automatically assigns an email address using a random domain from its pool. You can also manually choose or refresh for a new one.

🔒 Are domains reused?
No. Every domain is shared among many users, but the full email address (prefix + domain) must be unique per inbox. Once created, your address is private during its lifecycle — emails remain viewable only by you during the session.
