My favorite ways to use the BCC function are when I want to:
• Show one person’s superiors that they are doing excellent work, silently, to their superior
• Let a non-client facing team member know what is happening with a client, so they can do their best work behind the scenes
That’s about it. There may be others, but, generally, I don’t like BCC for mass emails, or for anything that should be transparent.
It’s a good tool for team building, not team breaking or writing to one person.
I’d rather use a template and paste 40 emails 40 times, individually, adding something personal to each one.
That may not sound ‘efficient’, but, I believe you can tell the difference between a note and a blast.
