Start using Custom Domains

What are custom domains?

Custom domains let you create temporary email addresses under your own domain instead of relying on shared generic domains. This gives you real control: only you can access emails sent to your domain, so no one can read your mail or intercept verification codes. You own the inbox, you decide when it expires, and you're never locked in to a vendor.

Since you control the domain, shared services can't block it. Your custom domain works just like any normal email address everywhere - whether you're signing up for SaaS trials, testing services, or creating accounts for privacy.

Use our API to build workflows at scale: QA testing across multiple environments, automated account creation in staging/dev systems, or managing large numbers of test accounts without manual setup. Our 99.9% uptime means your custom domain works when you need it. Questions? Check our help center for detailed guides and troubleshooting.

Always available and private

Only you can read emails sent to temporary emails on your domain, while public temporary emails are visible to anyone who knows the address. And your addresses stay online no matter what - we never rotate or deactivate them.
