So long as you communicate with your retained attorney for the purposes of obtaining legal advice, it should be covered. You may want to include in the subject 'attorney client communication' but this does not per se cover all communications. You should include a disclaimer in your signature block. Agents may not have the same legally recognized privilege. You may also include a disclaimer on some documents you prepare for your attorney.
DISCLAIMER: This information is intended for public and educational use only, it does not form an attorney-client relationship and it is not intended as legal advice. Nothing replaces a confidential consultation with an attorney. This communication may be considered attorney advertising. Do not post any privileged information, instead contact an attorney directly.
Be careful how you email. If you use an employer's email, computer or server the email may not be privileged.
The above answer, and any follow up comments or emails is for informational purposes only and not meant as legal advice.
It is privileged, but, email is not entirely secure. So you need to keep that in mind.
You also want to make sure you use your own email account and not an account accessible by a third party such as an employer, friend, spouse etc.
