Please choose the correct ending to complete the given sentence: Computers and Electronics: [header] How to write professional emails [title] Use the subject line wisely. [step] Rather than filling the subject with one or two vague terms, let the recipient know up front what they can expect from your email. Otherwise, it might fail to make the impact that it's supposed to.

Ending1: [title] Include salutations in the subject line. [step] While this won't do you much good, it will make the email more professional. Ending2: Be as specific as possible when supplying a subject for the email without becoming overly wordy. [substeps] " upcoming health inspector visit " is a stronger subject title than just " health inspector " when in doubt, think about what prompted the email in the first place and describe the situation in a few words. Ending3: [substeps] Avoid using precursor phrases like " how are you? " or " what do you think you should do today? " while these messages may sound generic, they might seem impersonal if used poorly. Instead, make the recipient more inviting by using language that indicates appreciation, and's often the subject line of professional emails. Ending4: [substeps] For example, if you were just trying to reach out to your husband via email, outlining what would be expected of you could be distracting from the purpose of your email. [title] Use subject lines that emphasize each one.
