A dwarven magus must enter a world he grew up only hearing of. As he strives to find his place and faces numerous dangers (and at least one too many gnomes) his naivete in life and love may bring more danger than any enemy ever could.
Actually, I’ll take it a step further: Don’t mass-email people if you haven’t asked them to opt in to your mass email list. I’ve been added to multiple mailing lists without signing up. And most of them also have no easy option to unsubscribe.
(I’d be less bothered by this if most of the mass emails weren’t asking me to pre-order a book I already ordered, but that’s beside the point.)
The reader update module on the site is a wonderful tool that bakes in the reader’s right to opt in or out. People who follow your book have told you it’s totally cool to send them updates through that. Anything beyond that, you need to ask.
There’s another reason to heed this (other than not upsetting people you want to order your book): Email addresses are personally identifiable information and protected by privacy legislation. By not using BCC you are distributing those email addresses without their permission which in many jurisdictions is a big no no.
No-one is likely to come after you over it - it is far from a disastrous breach of privacy and there are bigger fish, but it really isn’t a good move when you are trying to promote yourself.
I honestly don’t understand when and how this mass-emailing thing started. There are several means of communication through Inkshares that guarantee privacy for those following projects.
Also, BCC should be just common sense. It baffles me that someone wouldn’t know that.
@Brian Marsden - Good point about not everyone realising about BCC - I’ve thrown together a quick post that hopefully helps explain both why to use it and how: https://robertbatten.net/2016/08/04/using-bcc-with-multiple-email-recipients/
