Can We Use Smileys in Official Emails to Express Emotions? Seeking Your Thoughts

Hello,

Please inform me whether we can use smileys to convey our emotions while writing official emails.

Thanks in advance for your replies.

No, be formal,while writing any official mails.
When you are writing some invitation mails,……… for party or gathering (if not formal)you can use then only. Otherwise simply no……….

Thanks for the reply,

To be precise about the question, if the meeting agenda includes mentioning the birthday celebration of the staff members who will be treating us during their attendance in the meeting, can we use cheerful or clapping smileys in such scenarios to add enthusiasm to an email.
