Someone just mailed me their entire customer list. And not just me, but all others on their list. What a embarrassing and expensive mistake!
Unfortunately accidents like this are still far too common. I regularly get sent customer lists. These lists does not come as an attachment. However you can read, and copy if you wish, all other recipients from either To or Cc-field of the email itself. Someone has again used regular email instead of marketing email software for the job.
In this post I'll tell you how to do it, if you absolutely need to do it, and why you should never send email campaigns, not even invitations to your event, from your regular email client program, such as Outlook, Gmail, Apple Mail etc.
