I'm torn by the necessity of sending regular contact to customers and the desire to wait until I have something important to say. It's a natural tension, and one I just have to confront on a monthly basis. If I haven't found something to email about at the end of the month, then I have to give up and email something anyway.
"I still care about you" is the message I'm trying to convey.
Code School blog: Forget About Clicks, Design Emails With Purpose, 2015-May-15 by Corey Rabazinski
Here at Code School, we spend a lot of time thinking about, designing, and analyzing our emails. They’re not only a great way for us to communicate with the Code School community, but they’re also some of the most viewed “pages” under the Code School brand. In April alone, 4 of our emails were opened by over 200,000 people. Over that same time, only 2 of the pages on our site were seen by that many unique users.
But with great power comes great responsibility — we understand and respect that the inbox is not something to be abused.
