control panel > member management > view/edit members > button submit (lists all users) > scroll to bottom > set "Action" to "Email", set "All Members or Selected Members?" to "All Members in Search" > button "Perform selected action" > set "Available email options" to "Send mail directly to members" > button "Generate emails" > enter subject and body text, consider the "BCC" checkbox because all emailees might see each others email addresses else > button send mail

If you want to practice feel free to add me, and yourself eg to test the BCC setting. O, don't choose "All Members in the Search" then
