“Check your writing 检查文法”
Make sure the email is free of grammar and punctuation errors. It tends to look less professional if it's rife with mistakes, which may mean your email won't be taken seriously.
“Stay professional but friendly 语气专业且友好 ”
Watch the tone of your email. Make sure you keep it professional but friendly. And remember not to go overboard with the friendliness. Stay clear of emoticons, an excessive amount of exclamation marks, and capitalizing words for emphasis — you're not a used-car salesman.
“Keep it short 保持简短”
Try to be as brief as you can. If the person does not know you, she is less likely to spend time reading your email. If you keep your emails short, she's more likely to get through the whole email.
You're writing the email for a reason, so you should be clear about your goals. It's even helpful to be specific in the subject line as well, says a former Google recruiter. Using bullet points may also help you get your point across more quickly and help the reader figure out what you want.
“Don't bombard 不要发很多邮件狂轰滥炸”
If you haven't received a response, don't keep sending multiple emails in hopes that the person will finally cave. Instead, spread your emails out and limit them. Follow up one week after the initial email, and if you still haven't heard back, send the third email two weeks later. And if no one responds to your third email, it's time to switch gears and try something else. Also, if a person says that they will get back to you if they are interested, you should probably wait for them to get back to you.
If the email is not working, try other means such as interacting with her on social media or meeting in person. Remember, there is a fine line between being persistent and a pest, so do your best to toe that line.
