Can we write hi in business mail

While "Hi" is a friendly and informal greeting, it's not typically used in formal business emails. Here are some alternative greetings you can use in a business email:

1. Dear [Recipient's Name]: This is a classic and professional way to start a business email.
2. Hello [Recipient's Name]: This is a bit more casual than "Dear," but still professional.
3. Good [morning/afternoon/evening] [Recipient's Name]: This greeting acknowledges the time of day and is suitable for most business emails.
4. To Whom It May Concern: This is a more formal greeting that can be used when you don't know the recipient's name.
5. Dear Sir/Madam: This is another formal greeting that can be used when you don't know the recipient's name.

Here are some examples of business email greetings:

• Dear John Smith,
• Hello Jane Doe,
• Good morning, Sarah Johnson,
• To Whom It May Concern,
• Dear Sir,

Remember to always use a professional tone and language in your business emails, and avoid using overly casual greetings like "Hey" or "Hi."
