Add Your Own Domain to the Email Generator
This guide explains how to point your own domain at our service so that you can receive mail at any address on that domain through the email generator. The setup takes roughly five minutes; the only delay is DNS propagation, which is automatic and outside our control.
Step 1 — Register a domain with an accredited registrar
Buy the domain directly from an ICANN-accredited registrar instead of a reseller. Direct registration gives you full control over DNS records and transparent renewal pricing. The complete list of accredited registrars is maintained on the ICANN website:

example.com) are treated as more trustworthy by sign-up filters than long subdomains (foo.bar.example.com). Short = better. Step 2 — Create an MX record pointing at us
In your registrar's DNS settings (sometimes called «Zone editor» or «DNS manager»), add a new MX record with the following values. Field names vary slightly between registrars — the right column shows the most common variants.
@, or your domain nameMX86400 (24h cache)1generator-email.com.generator-email.com. — most registrars require it (it tells the DNS resolver «this is a fully-qualified domain, do not append my own zone»). A few registrars reject the trailing dot and add it for you automatically — in that case enter the value without it. If you are unsure, save it without the dot first, and add the dot only if delivery does not work after 24 hours. Step 3 — Wait for DNS to propagate
DNS changes spread across the global resolver network at their own pace. In our experience the new MX record becomes active for most senders somewhere between 1 minute and 24 hours, with the median around 5-15 minutes. There is nothing to do during this period — just wait.
If you want to verify the record from the command line:
dig MX yourdomain.com +short
The output should contain 1 generator-email.com.. Once you see this, the email address generator on your custom domain is live.
Step 4 — Start using your custom domain
Open the site with your domain in the URL:
https://generator-email.com/yourdomain.com
The page works exactly like the standard email generator — you can type any username before @yourdomain.com, paste the resulting address into sign-up forms, and watch incoming mail arrive in real time. Notifications, attachments, multi-tab inboxes — everything works the same as on our shared domains.
Why owning the domain is worth it
Our shared free email generator domains are convenient — no setup, instant access — but they have one fundamental limitation: they are not yours. We rotate them as blocklists grow, and any single domain might be retired in the future. Your custom domain solves this in three ways:
- Permanence. The domain stays in our dropdown as long as you renew the registration. No surprise retirements.
- Reputation. A fresh personal domain is rarely on sign-up blocklists, so it works on services that reject our shared ones.
Troubleshooting
«My domain still doesn't show emails after a day.»
- Re-check the MX record — both the value (
generator-email.com.) and the priority (1). - Try with and without the trailing dot.
- Some registrars require a second confirmation step before DNS changes take effect (verification email, lock release).
«The sign-up form rejects my new domain.»
- Fresh domains take a few weeks to build «trust» reputation. Wait and retry, or use one of our shared domains for that particular sign-up.
- Make sure the domain has a valid MX record (browser sites use it as a quick «is this a real address?» check).
