Temporary email vs real email: which to use, and when
Use a temporary email when you will never need the account again and would not mind a stranger reading its mail; use your real email for everything else. The difference only shows up later, when a site needs to reach you, reset a password or confirm the account is yours. This guide sets out what each is for, with examples on both sides and a checklist to run before you paste an address in.

What each kind of address is for
A real email is for being reached; a temporary email is for getting past a form. Your own address is yours alone, it lasts as long as you keep it, and it is where a site writes when something matters: a receipt, a security alert, a password reset. You can prove it is yours by reading the mail, today or years from now.
A temporary address is the opposite on almost every count. The ones here are real gmail.com addresses on shared accounts, free and instant, with no sign-up. They receive mail, show any verification code beside the message, and keep your own address off one more list. But they are not yours, anyone who knows one can read it, and the provider may recycle one at any time.
Neither is better. They do different jobs, and most trouble starts when an account meant to last is given an address built for a single use.
A rule of thumb for temporary email vs real email
If a site might ever need to reach you about something that matters, give it your real address. Something that matters means money, security, official business, or an account holding things you would miss. If none of that applies, and you would not care if the account disappeared tomorrow, a temporary address is fine.
A temporary address fits a download held back until you click a link, a forum or comment section you will visit once, a coupon code, a newsletter you want to read one issue of, a free trial you will not continue, or a test account in software you are building.
Your real address belongs on banking and payments, shopping where you pay or might want a refund, government, tax and health services, work and school, your phone and app store accounts, social media you keep, and any account that guards other accounts, such as a password manager.

Get temp mailWhat happens later to an account on a temporary address
An account tied to a temporary address keeps working until it needs that address again, and then it is stuck. The first sign is usually a password reset. Forget the password and the reset link goes to the temporary inbox. If the address has been recycled, or has dropped out of your list of recent addresses, the link arrives where you cannot read it and the account is as good as gone.
Recovery works the same way. A site that checks it is really you by sending an email, before an address change, after a strange login or when you ask support for help, can only write to the temporary address. On a shared address, someone else who knows it could ask for a reset and take the account over, which is why the risks of temp mail are mostly about what happens afterwards.
Receipts and notices go missing too: order confirmations, renewal reminders, changes to terms, the warning that a free trial is about to start charging. If any of those would matter to you, the account needed your real address.
Moving an account to your real address
If an account on a temporary address turns out to matter, change its email to your own while you can still read the temporary inbox. Most sites let you change your email in the account settings. Some confirm the change by writing to the old address, some to the new one, some to both, so do it while the temporary address is still in your list and still receiving mail.
Do not leave it until you need a reset. There is no expiry timer here, but nothing guarantees how long an address lasts, as how long temp mail lasts explains, and by the time you need the mail the address may have been recycled.
And if you suspect you will come back to a site, skip the step entirely. Use your real address from the start, or a second address of your own for sign-ups you want kept apart from your main inbox.
A quick checklist before you choose
Ask four questions, and if any answer is yes, use your real email. Will I pay this site or give it card details? Will I need this account in a month? Could a stranger reading this mail harm or embarrass me? Will the site send anything I may need to show later, such as a receipt, a ticket or a contract?
If every answer is no, generate a temporary Gmail address and use it. Copy the code when it arrives, finish the sign-up and move on; whatever that site sends afterwards goes somewhere you will never look.
Whichever you choose, the rest of the form still counts. Your name, phone number and payment details identify you whatever email you gave, so a temporary address keeps your inbox out of it, not you.
Questions
Can I switch an account from a temporary email to my real one?
Usually, if the site lets you change your email in the account settings. Do it while you can still read the temporary inbox, because some sites confirm the change by writing to the old address.
Should I use a temporary email for online shopping?
Not when you pay. Order confirmations, delivery updates and refunds all go to the address you gave, and you may need them later.
Is a second email account of my own a better middle ground?
For sign-ups you want to keep but not in your main inbox, yes. A second address you own is private and recoverable, which a temporary one is not.
