It is polite to ask for a job by 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
When you ask for a job with a friend working in a company you should be polite. It is important to be clear about your goals and capabilities, as well as sharing information about your past experience. Do not send them letters asking for jobs. Simple letters with only a few lines are sufficient.
While it might feel awkward, remember that you're not asking for a friend’s recommendation because of friendship. If you do ask for a friend's recommendation, it shouldn't be a problem. Make sure you acknowledge your friend's help by expressing your gratitude.

In the email, introduce yourself
Focus on the person reading your introduction email when writing it. You can start with a flattering compliment or mention something that is common such as having grown up in the area. Then explain why you are writing the email. Maybe you were in contact with someone and they sent you their email address.
Your introduction is as good or bad as the subject line of your email. It should be interesting and concise about who and what they are. Most people are inundated with emails, and may be hesitant to open one from a stranger.
Avoid asking for a recommendation from a friend
While it may be awkward to ask a friend for a recommendation when applying for a job in the workplace, there are simple ways to avoid awkward situations. 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. Most people are happy to help a friend, but they'll often hesitate to recommend a friend to their current employer. Before recommending a friend to your potential employer, make sure they're the right person for the job opening.

Avoid sending the email from your work account
First, don't send inappropriate emails to work email accounts. This goes double for receiving inappropriate emails. Ask your friend to stop sending unsolicited emails from his/her work account if you are unsure if an email is inappropriate.
To send job inquiries, you shouldn't use your employer email account. It is better to use your personal email account to send job requests. Reduce the number of emails you send from your work email account to help you land your first job.
