I realize there are potential regulatory reasons to not offer this ability, but we are trying to maximize our personalization potential for legitimate business purposes.

Hi there!

Thanks for a great suggestion, for the sake of writing a response for others to find, I've gone ahead and altered the title to the question, "Why is there no ability to use the Carbon Copy (cc) and Bind Carbon Copy (bcc) fields in a bulk mailing?" 

You're spot on in assuming there are reasons behind this, privacy, security, deliverability and best practices are at the center of these.  Below I'll go into some more detail for you:

  • Privacy - The use of 'cc' means that everyone that is on that receiving list will be able to see everyone else that's been sent the same mailing.  In other words your audience is having their email address shared with people they don't know.  Furthermore, if someone accidentally (or not) selects "reply to all", everyone on that mailing list will receive their response.  This would be a fast track to losing a large amount of your audience via opt-outs.  Maybe you're thinking, "well using 'bcc' doesn't show other's contacts details so what's the big deal?" well, you would be right, except unfortunately it's just too easy to accidentally use the wrong field - and it does happen - and that would compromise your entire audience's privacy.
  • Security - Using 'cc' and 'bcc' open up your emails to the spread of viruses.  If one of those emails receiving your mails has an email-transmittable virus, all other contact's inbox can be compromised.  I don't need to explain why this is a bad thing.
  • Deliverability - 'Cc' and 'bcc' simply weren't designed for email marketing or bulk emails.  When a receiving server sees a bunch of addresses in the 'cc' or 'bcc' field it's a massive red flag for spam.  Most likely, that receiving server will trash the email and you'll have no idea if it was received by your audience or not.  Or in a worst case scenario, some receiving servers will move those contacts from the 'bcc' to the 'cc' field.
  • Best Practices - Enabling the use of the 'cc' and 'bcc' fields unfortunately encourages people "gaming" the system.  It's too easy to send to people outside of their list and it's too easy for folks to get themselves and their email service provider blacklisted for not following the rules.

I hope I've been able to shed some light on this for you, but if you have any questions, or if you'd like to share what you're trying to do I'd be happy to work through something to help you increase the personalisation of your mailings. Please let me know :)
