What are some common mistakes to avoid in Emails?

Answer

• Misspelled Names: It gives a bad impression.
• To whom it may concern: it is better to be specific to whom the email is being addressed. 
• Punctuation error: helps the reader understand how to interpret what has been written.
• Dear Sir/Madam: This salutation is genric; shows that you couldn't even a contact name.
• Informal Language: Do not use informal phrases like "whats up?", "dude" etc.
