Commas in emails
The basic rules of using commas can be also applied in emails. The specific features of an email are the usage of commas in formal greetings and formal endings:

• Dear Mrs Johnson,
• Hello there,
• Yours sincerely,
• Best regards, etc.

NOTE! When you sign the letter, remember that there is no full stop after the name.

Lots of love,Andy

Now read the greetings and the endings and choose the correct punctuation marks:

• Dear Sam[,|.|!]
• Hi [—|.|!]
  Mary[!|.|,]
• To whom it may concern[.|,|—]
• Sorry[,|.|;] I have to finish now. My mum is calling me.
• Best wishes[.|,|:]
