Choosing an address that sign-up forms accept
What makes an address get accepted?
Two things: it looks like a person, and it lives on a real mail domain. Addresses here are generated as a first name, a full stop and a surname — daniel.hayes@… — on domains this site owns and runs. That is the shape ordinary personal addresses have, and forms treat it accordingly.
Why random addresses get refused
x7f2qk9v@… is the signature of a throwaway generator, and a lot of sign-up forms match on exactly that: length, entropy, no vowels, no name. The address does not have to be fake to be refused — it just has to look like the ones that usually are.
Nothing here can promise universal acceptance, and any service that promises it is guessing. What this site can do is not hand you an address that announces itself.
Choosing the domain
When more than one mail domain is available, a Domain dropdown appears next to the Generate button. Pick one, or leave it on "Any domain" and one is chosen for you. If only one domain is available, the dropdown does not appear and that domain is simply used.
There is no "best" domain. If a particular service refuses one, generate another address on a different domain and try again.
If a form still says no
- Generate a new address (a different domain if you can choose).
- Check the form is not objecting to something else — some forms reject a full stop in the local part, or an address longer than they expect.
- If a service refuses every address, it maintains its own list, and the honest answer is to use an ordinary account for that one.
One address per service
Generating a fresh address for each sign-up costs nothing and takes a second. It keeps services from linking your accounts through a shared address, and if one address ends up on a marketing list, only that one is affected.
Where the names come from
First and last names are drawn from curated lists of ordinary given names and surnames, mixed and balanced, with celebrity and brand names excluded. If a name pair is already taken on a domain, the next form is tried — a middle initial, a number, or the two names joined — so you always get something that still reads like a person.
Can I choose the name myself?
Not on the public site. Letting visitors type any local part invites impersonation (support@, billing@, someone else's name) and the abuse reports that follow, which end with a domain being blocklisted. Reserved names such as admin and postmaster are never issued at all.
Does the domain change what arrives?
No. Mail is delivered the same way on every domain this site runs, and the inbox behaves identically. The only difference a domain makes is whether a particular sign-up form has decided to refuse it.
