Disposable inboxes on a domain that belongs to you — so they pass the blocklist checks that reject shared temp-mail domains. Connect your own domain or use a private TempMaily dedicated domain.
Every free temp-mail service — TempMaily's free tier included — hands out addresses on a small set of domains that the whole internet shares. That's fine for a quick throwaway, but it has a cost: public disposable-domain blocklists crawl and index those domains within days.
Strict signup forms check every address you enter against those lists, so anything on a shared temp-mail domain gets bounced with the familiar "email not accepted" error. A domain that's yours alone isn't on those lists, which is exactly why it gets through. More on why websites block temp mail.
Upgrade to Premium — this unlocks custom domains, dedicated domains, up to 10 addresses, and forwarding.
Connect a domain you own by adding a couple of DNS records, or pick a TempMaily dedicated domain with no setup at all.
Mint disposable addresses on that domain — as many as you need, up to 10 active at a time.
Mail arrives in the same real-time inbox as the free tool, with forwarding to your real inbox and permanent addresses included.
Straight answer: a custom domain clears blocklist checks, but it won't get you into services that verify by phone or only accept corporate mail. No disposable domain of any kind will.
Privacy users who keep hitting "email not accepted." If shared temp-mail domains bounce on the signups you actually care about, an address on your own domain gets through where a throwaway can't.
QA and automation teams who need a stable, predictable domain for test accounts. Point the API at your own domain and automate email verification testing without your test domain landing on a blocklist mid-suite.
Anyone running lots of signups who wants addresses that survive past 24 hours and forward to a real inbox instead of vanishing on a timer.
Custom domains and private dedicated domains, up to 10 addresses at once, forwarding to your real inbox, permanent addresses, 2GB storage, and no ads — $9.90/mo or $90/year (save 24%).

Yes, on TempMaily Premium. Point a domain you own at TempMaily and generate disposable addresses on it — up to 10 active at once. Because the domain is yours and isn't handed out to the whole internet, it doesn't show up on the public disposable-domain blocklists that get shared temp-mail addresses rejected.
Free temp-mail services give everyone addresses on a small pool of shared domains. Public blocklists crawl and index those domains within days, and strict signup forms check incoming addresses against those lists and bounce anything that matches. Your own domain isn't on those lists, so it isn't flagged as disposable.
A dedicated domain is one TempMaily provides that stays private to your account rather than being shared with every free user — no DNS work, and it isn't publicly listed as disposable. A custom domain is a domain you already own and connect yourself, so addresses carry your own brand and you have maximum control. Both are included with Premium.
Not for a dedicated domain — you pick one inside your account and start using it immediately, no configuration. For your own custom domain you add a couple of DNS records at your registrar (the same copy-and-paste kind of records you'd add for any email service). If you'd rather not touch DNS at all, use a dedicated domain instead.
Yes. Premium addresses aren't wiped on the free 24-hour timer — you can keep an address long-term or permanently, run up to 10 at once, and forward incoming mail to your real inbox. That's what makes a custom or dedicated domain worth setting up: the addresses on it survive well past a throwaway window.
No, and we won't pretend otherwise. A custom domain gets you past blocklist checks that reject known disposable domains, which is the most common block. It won't get you into services that require phone verification, or ones that only accept corporate or established consumer email providers. For those, no temp-mail domain of any kind will work.
