Toady sees a BBC news report asking What's the cost of e-mailing 1.8m people? That is the number of people that the UK government e-mailed in response to an online petition.
For the answer to this question, the BBC ask Chris Lake, editor of e-consultancy.com:
"Last week I had lunch with someone who sends out 180,000 [e-mails] a week as a newsletter, which cost him £600," he says. "That would make it £6,000, but it could be much less or much more."
So, what's the cost of e-mailing 1.8m people? £6,000. Or much less. Or much more.
Thank you Chris Lake. You are my Pointless Expert of the Week.
