Final answer:
All the mentioned points, including sender's email address, subject line, attachments, and links, should be verified when receiving an email. Additionally, when sending an email, a professional email checklist should be used and the content should be proofread before sending. Always confirm with the recipient, like an instructor, regarding policies for email submissions.
Step-by-step explanation:
When initially verifying an email, all of the mentioned points need to be checked: sender's email address, the subject line, any attachments included, and links or URLs that may be inside the email content. It is essential to verify the sender's email address to ensure the email is not from a malicious source. The subject line should be clear and relevant to the content of the email. Care should be taken with attachments as they could potentially contain viruses or malware. Any links should be inspected cautiously before clicking to avoid phishing attempts.
Moreover, it's important to use a professional email checklist when composing emails, which includes ensuring you have an appropriate email address, a meaningful subject line, and the email contains no spelling or grammar errors. Before sending, always proofread the email for clarity and accuracy to make a good impression on the recipient. If sending assignments via email, always check with your instructor about their acceptance policy to avoid misunderstandings.
