OK, I'm DEFINITELY not one who likes receiving emails from a company. When unsolicited, they are generally annoying and invasive, offering little value to me.
I recently made a purchase with Clive Coffee and got on their email list by accident. Interestingly, I've been receiving weekly emails from them and for the most part have enjoyed the content and found it useful. I would think that the resources they provide would be a benefit for anyone who isn't already "expert" level.
Anyway, I have no affiliation with Clive, but wanted to throw them some kudos for creating solid content and delivering it in a way that actually worked for me.
