Yep. I receive newsletters from several merchants whose stuff I regularly buy. I like getting coupons and information about new products. This is stuff like coffee and chocolate, mostly foodstuffs that I consume regularly.
I delete most of them after reading, act on maybe 1 in 4.
I'd be very surprised if my behavior here was atypical for consumer behavior.
Some of my favourite "blogs" are only available in the form of e-mail newsletters. patio11's post-BingoCardCreator blog, for example, only existed as a newsletter (with non-indexed webpage alternates) for the longest time—though I see that there's now an index (http://www.kalzumeus.com/archive/), complete with RSS meta-tag.
In other cases, newsletters can serve as a sort of low-volume link aggregator. I'm subscribed to the http://elixirdose.com newsletter and end up with a few Elixir-related articles to read each month.
In other cases, it's just fun to follow regular company newsletters, because those companies are essentially soap operas in progress. The http://zenmagnets.com newsletter is 90% about their ongoing legal battle against the Consumer Product Safety Commission.
And, every once in a while, I appreciate getting informed that a product/service I've built something on top of—but which I'm not actively building on right now (i.e. I pay them money every month, but I never go to their website)—has new features, which might inspire me to build something else on them. I like getting announcement emails from {AWS, DigitalOcean, Twilio, etc.} for this reason.
I read Javascript/Node/goweekly.com newsletters in their email format. The Phaser.io newsletter is another. I think you're more the outlier than the norm.
I don't think I've ever set foot in the 'Promotions' tab in my Gmail account, other than to delete everything in it.
