I must be unlucky with usage of disposable emails, because every time I remember about them and try to use them, service where I use them says that their domains are banned or prohibited and ask to use other email. This happens 200% of the time I use
https://10minutemail.com/.
I have simply registered an email on mail.com and used a password like abc123. Easy to remember password, easy to register, services will accept this kind of emails.
Protecting your email from spam, bots and phishing by
https://temp-mail.org/.
It's a service I've been using as a
browser extension for several years now. (Brave/Chrome)
Temp-mail only allows receiving emails and cannot be used for sending. And there is no way to save letters for more than 1-2 hours, but this is not necessary.
I tried
"10minutemail, guerrillamail, mailinator, getairmail, throwawaymail" but settled on tempmail
You can see the extension appears in the login / email input field.
