You should be polite when asking for a job via email from a friend. You should not send an email from your personal work account. You don't want to be seen as a friend that needs a recommendation.
Always be polite
You should ask for a job from a friend who is employed in a company. It is important to be clear about your goals and capabilities, as well as sharing information about your past experience. You should not bombard them with letters asking for a job. A simple letter of a few sentences will suffice.
While it might feel awkward, remember that you're not asking for a friend’s recommendation because of friendship. You should be polite when asking for a referral. This won't change your friendship with your friend. Recognize your friend's assistance by thanking them.

Please introduce yourself in the email
Send an introduction email to the person who will read it. Start with a flattering compliment, or mention something in common, such as growing up in the same area. Then explain why you are writing the email. Perhaps you had a mutual contact and received their email address.
A well-written email subject line is crucial for a successful introduction. Your subject line should be clear and engaging. It should also explain who you are and what your goals are. Many people are overwhelmed with emails and might be reluctant to open an email from someone new.
Avoid asking for a recommendation from a friend
Although it can be awkward to ask for a recommendation from a friend when you're applying for a job, you can safely avoid this awkward situation by following a few simple rules. These rules can help you navigate delicate matters while also protecting your professional reputation.
Although it is a friendly gesture it should not be taken too far. Although most people are willing to help a friend, they may hesitate to recommend them to their current employer. Before recommending a friend to your potential employer, make sure they're the right person for the job opening.

You should not send the email from work.
First of all, it is important to not write anything that would be considered inappropriate for a work email account. You should also avoid receiving inappropriate emails. Ask your friend to stop sending inappropriate emails from their work account if you aren't sure if it is appropriate.
Sending job requests should be done from your personal email address. It's better to send emails from your personal account. If you're trying to land your first job, cut down on emailing from your work account entirely.
