01Is it a real Gmail address?
Yes. It ends in @gmail.com and mail reaches it through Gmail like any other, so to the site it looks exactly like an ordinary user. The only difference is that it is not yours personally, and it is not tied to your phone number or real details.
02Do I need to sign up, or give a phone number?
Neither. Free users claim one straight from the page — no NexMask account, no Google account, no phone verification. Membership is only needed to claim in bulk or hold several at once.
03Can a temp Gmail receive verification codes?
Yes — that is what it is for. Sign-up codes, confirmation links and login alerts all arrive. If one is slow, refresh the inbox; if it still does not show, ask the site to resend, or try another address.
04Can I log in to Gmail with it, send mail, or use “Sign in with Google”?
No. You get the ability to receive at the address, not the Google account behind it: no password, no Gmail web login, no sending or replying, and no “Sign in with Google”. Any sign-up that asks for an email address and sends a code to it works fine. When you need to reply anonymously, use a long-lived alias, which can send as the alias from the console.
05Can anyone else read my mail?
No. While you hold a Gmail address, its inbox opens for you alone; someone who knows the address still cannot get in.
06Why not just use a +alias or the dot trick on my own Gmail?
Those sort mail; they do not hide you. Strip “+shop” from [email protected] and your real address is right there, and dotted variants all land in the same inbox — plenty of sites and marketing systems undo both automatically. A separately claimed Gmail address has no link to you at all.
07How long does a temp Gmail last?
The lifespan is shown when you claim it, and members keep theirs longer. It suits codes and confirmation mail, not accounts you will need to recover later — for those, use a long-lived alias, which stays valid and forwards into your everyday inbox.
08Will Google know who I am?
Mail to any @gmail.com address is received and stored by Gmail — that is simply how Gmail works. But you never registered this mailbox, so it is not connected to your name, your phone number or your Google account. Keep in mind that the site you sign up to can still see your IP address and device fingerprint; real separation means dealing with those clues too.
09Is NexMask affiliated with Google?
No. NexMask is an independent privacy email service, with no affiliation, endorsement or partnership with Google. Gmail is a trademark of Google LLC and is used here only to describe the address suffix.
