Temporary Mail (https://temporarymail.com/)

Here is what sets this site apart from the others:Site let's you choose between multiple domains that are each using unique hostnames and IPs so they don't get detected.
The emails are shown in sandboxed windows meaning that your IP won't leak to the sender and they won't know if you've opened the email even
though you can view the HTML version of the email.
All external images are blocked and are only opened when you click on them and accept the warning.
Let's you choose any username with the supported domains (e.g [email protected]).
Emails are automatically deleted after 6 hours both to ensure your privacy and to avoid having anyone else read them.
