Your question just says 'Email' - it would be helpful to type the question as vertually everything to do with Thunderbird is email. The additional info to support your question, says you need help with sending, but you have not provided any information. So I do not know what problem you are experiencing, could you supply some additional information so we get an idea of the problem. What OS are you using ? What version of Thunderbird are you using? What are the outgoing server SMTP settings you are using to send emails ? When you say you need help, what is the problem? Do you get any error messages when you try to send emails? If yes, then you need to let us know what is that error message - word for word.
