How to send email using Mozilla Thunderbird

Sending an email using Mozilla Thunderbird is a fundamental task for anyone managing online communication, especially in roles like website development and server administration. Thunderbird is a versatile email client that allows for efficient email management. Here’s a detailed guide on how to compose and send an email using Mozilla Thunderbird:

Steps to Send an Email in Mozilla Thunderbird

1. Open Mozilla Thunderbird

  • Launch the Thunderbird application on your computer. Ensure you’re logged into the email account you want to use for sending the email.

2. Compose a New Email

  • Click on the ‘Write’ button, usually located at the top left corner of the Thunderbird window. This opens a new message window.
  • Alternatively, you can use the keyboard shortcut Ctrl + N (or Cmd + N on a Mac) to open a new message window.

3. Enter Recipient Details

  • To: In the ‘To’ field, enter the email address of the recipient. If you are sending the email to multiple recipients, separate each email address with a comma or semicolon.
  • Cc (Carbon Copy): Use this field to include recipients who should be aware of the email but are not the primary audience. Recipients in the Cc field can see the other recipients of the email.
  • Bcc (Blind Carbon Copy): If you want to send the email to someone without other recipients knowing, use the Bcc field. Recipients in the Bcc field cannot see the other recipients of the email.

4. Subject Line

  • Enter a concise and relevant subject line. This helps the recipient understand the email’s purpose at a glance.

5. Compose Your Message

  • In the large text area, compose your email. Thunderbird provides various formatting tools for styling your text, adding bullet points, changing fonts, etc.
  • For a professional email, use a standard font and format. Keep your paragraphs short and to the point for better readability.

6. Attach Files (If Necessary)

  • To attach a file, click on the ‘Attach’ button (usually represented by a paperclip icon) and select the file(s) you wish to attach.
  • You can also drag and drop files directly into the email body.

7. Add Hyperlinks, Images, or Other Items (Optional)

  • Use the ‘Insert’ menu to add hyperlinks, images, tables, and other items to your email.

8. Review and Send

  • Before sending, review your email for any spelling or grammatical errors. Ensure that your message is clear, concise, and maintains a professional tone.
  • Once satisfied, click the ‘Send’ button, located in the upper left corner of the email window.

Additional Tips

  • Saving Drafts: If you’re not ready to send the email immediately, you can save it as a draft and return to it later. Thunderbird automatically saves drafts periodically, but you can also manually save by clicking ‘File’ > ‘Save’.
  • Email Signature: If you have set up an email signature, it should automatically appear at the bottom of your email. Ensure it’s correctly formatted and contains up-to-date contact information.
  • Organizing Sent Emails: Use folders and categories in Thunderbird to organize your sent emails for easy retrieval in the future.


Sending an email with Mozilla Thunderbird is a straightforward process that becomes intuitive with regular use. By following these steps, you can ensure that your emails are professional, clear, and effective. As a website developer and server administrator, efficient email communication is key to maintaining strong professional relationships and managing your digital responsibilities effectively. Remember, the clarity and professionalism of your emails reflect directly on you and your organization, so it’s worth taking the time to get them right.
