Helping people with computers... one answer at a time.
Undisclosed recipients may be available in the headers of the sent email, or it may be hidden.
I understand "undisclosed recipients" being blocked from the person receiving the message, but is there a way to find out who I sent a message to that shows only undisclosed recipients? I'm using Thunderbird and Gmail.
In this excerpt from Answercast #27, I look at the way various email programs either reveal or hide a list of undisclosed recipients.
I honestly don't know about both Thunderbird or Gmail. It really varies depending on the program.
The thing to do is actually very simple. Go to the Sent mail folder in your email program. In the Sent mail folder, open up one of the messages that you had bcc'ed recipients on.
Make sure that all of the headers are visible. I know that Thunderbird only shows a subset of the available headers by default. You may need to look at All Headers. Or you could even use Thunderbird's View Source option to take a look at the actual source for the message.
It is very possible that the email program will show you exactly who the message was bcc'ed to – who the undisclosed recipients were.
Unfortunately, it's also equally possible that the information is not there.
Many email programs simply strip that information off before it is actually placed in your sent mail. In other words, there's no way to find out who you bcc'ed on an outgoing email in some email programs.
The bottom line is to simply take a look at the message in your Sent folder.
If the information is there, it should be displayed.
