Last year I sent a round robin Christmas letter to several friends by email. I am with BT/Yahoo mail. I wanted to know to whom I had sent the emails, so I did a search. The only one I came up with was the email I had sent to myself. I had been advised, a long time ago, to send a copy of an email like this to myself as well as the people it was intended for, so that I would know exactly what my friends would have received. I think I might have put the other email addresses in the Bcc section so that each person's email address would remain private. Could that be why I can't find the addressees? Is there any way that I can recover the addresses the email was sent to?
Thanks, Guilbert53. I tried that, but found nothing. It looks as though I didn't send a letter last year, after all, as I found the one I sent in 2016 with no problem -- I sent the same letter individually to each person.
