You can send email using Thunderbird.
1. Open Mozilla Thunderbird.


2. On the left side of the Top menu, Click on the “Write” option. It is so easy because you do not need to physically login to cPanel webmail and you can directly send email using the Mozilla thunderbird Email client.



If you have multiple email accounts, click on your account and a drop-down menu will open. Then choose the correct email and insert the email account of the person you would like to send an email to in the “To” field.

In subject option, insert the subject of your email, insert your message in the message box, and then press on “Send”.
