The Sticker Mule email arrived in my inbox, but I didn’t see it at first. Instead, I saw the backlash on Threads.

Here’s the thing, I knew the owner was conservative, but it didn’t really matter to me. I’d randomly order stickers (or keychains) whenever they had a great special. And they ran specials a lot.

Many companies take stands on issues as a way to signal their values. But most of the time, those topics are carefully chosen to align with their customer beliefs. There is an entire discipline in public relations scholarship called Corporate Social Responsibility that studies this strategy.

But this crosses a line. Blasting your entire business mailing list with a political message — a mailing list that is a massive asset to your sales funnel — is just stupid.

Why? You are choosing to voluntarily spam your mailing list with a political message that half of your list likely finds objectionable. Look at the last two presidential elections. Over half of the U.S. voted against him. Twice.

And add to that the nerve of trying to use an attempted assassination to sell shirts. Incomprehensible.

Anyway, I unsubscribed. I’ve got a Sticker Mule sticker on a water bottle that I’ll cover up. I’ll find another vendor and he’s apparently got plenty of business from people that agree with him.
