If you mean buying a list or finding a chamber list online and start emailing them information, the general answer is no.  Most B/D’s won’t allow you to do this without first gaining permission.

I know that with my B/D, e-mails can only be sent to clients or people who have given explicit permission.  I don’t know if this is FINRA or just my B/D.

Look up CAN-SPAM rules. That is what they are going off of. 

Nah, that’s pretty much standard in the industry.  Sort of like Do-not-call for e-mail.

We need compliance approval for any piece going out to more than 10 people via regular mail or email.
