Thanks for the reply. I meant doing everything through "Tor browser"----
write an email but set the sending date as 1 month later. Then closed the

Just wonder if the email send automatically by itself 1 month later, the IP
is still anonymous? or it's shows the IP / Location/ Machine? As by the
time the email sent, the tor browser closed although everything had been
set within Tor Browser 1 month earlier.

If you mean 1) setting up a completely anonymous email acct using TBB, then 2) always using TBB & only TBB to connect to that email (server), then it shouldn't matter when the email message is composed or sent. It also depends to an extent on the email provider. Some don't include your IPa in email headers, nor log it. Even if they do, if all communication w/ the email server (or webmail) is through TBB, they only see the Tor exit relay address.

One possible exception might be if one uses an email client (possibly including addons, plugins) rather than the provider's webmail, that isn't configured correctly to use Tor network, or doesn't strictly follow settings to use Tor. There are other possible ways that anonymity could be compromised.

Using webmail vs. an email client (like Thunderbird) may not be as convenient, but eliminating the client means one less thing that could possibly compromise anonymity. TBB is *highly configured* to protect anonymity, where email clients generally are not. When using email clients, it's largely up to users to configure them (vs. TBB ), then a matter of whether the clients will follow the configurations and / or have security issues or information leaks.

Torbirdy - https://addons.mozilla.org/en-us/thunderbird/addon/torbirdy/ - "configures Thunderbird to make connections over the Tor anonymity network" - can be used, but it's still BETA.

The author also states, "This is an experimental add-on and it requires that a user has Tor installed.

It currently contains known leaks and until we have something feature complete without *known* leaks, we consider it experimental."
