Unlike many temp-mail services that auto-generate random addresses, FreeCustom.Email lets users choose any custom alias (e.g., myalias@saledomain.live), giving them control and meaningful context when using temporary emails.
We offer a variety of domains (like saleis.live, arrangewith.me) that rotate frequentlyโhelping avoid blacklists common with single-domain services.
Our platform is built to remain completely free and ad-free, foreverโno obstacles, timers, or sneaky paywalls.
We launched an open-source Next.js/TypeScript frontend on GitHub, plus a robust backend API via RapidAPIโmeaning developers can run their own temp-mail sites or integrate our API into their projects.

| Clean, privacyโfirst UI | With zero ads and clear messaging |
| Developer empowerment | Open-source frontend + API = build your own or extend ours. |
