I am trying to send a email to a list of email addresses separated by a comma in the bcc section of the mail. When I hit the "Send" button, I get an error stating that one of the email addresses is incorrect. The email address in question is the fifteenth entry in the list. In all, there are 300 entries. I am not sure what button I pressed when I got the error message, but now the email is still sitting in the outbox. I am not sure if it sent any of the emails out at all or only sent emails to the first fourteen entries and then stopped when it encountered the faulty email address or whether it sent them to everyone except the one email in question. I would like to delete that particular email address and try sending them out again, but I do not want to send out the same email more than once to the same person.
Can someone advise me on how I should proceed?
