Can i write mail as dear concern

A common question!

In general, it's considered more formal and professional to use "Dear [Recipient's Name]" or "Dear Sir/Madam" when addressing a letter or email. "Dear Concern" is not a traditional or common way to start a letter or email.

However, there are some exceptions and nuances to consider:

  1. Formal or official letters: In some cases, you may use "Dear Concern" in formal or official letters, such as when addressing a government agency, a regulatory body, or a formal complaint. For example: "Dear Concern, Re: [Specific Issue or Complaint]".
  2. Informal emails: In informal emails to friends, family, or colleagues, you may use a more casual greeting, such as "Hey [Name]" or "Hi [Name]". In this case, "Dear Concern" might be too formal.
  3. Special circumstances: In some situations, "Dear Concern" might be used to express empathy or sympathy, such as in a condolence letter or a letter to a victim of a tragedy.

If you do decide to use "Dear Concern", make sure to use it in a formal or official context, and consider adding a brief explanation or context to clarify the purpose of the letter or email.

In general, it's always a good idea to use a formal greeting when writing a letter or email, especially if you're unsure about the recipient's preferences or the tone you want to convey.
