Documenting the move to beehiiv
"I love email as a medium. With email, you don’t have to remind people where to go. There’s no contorting your content to show up in an algorithm. Your only job is to make your email worth reading."

This is a tough question, and it’s one that every content marketer should constantly be asking. Whether your strategy is “working” is not always a clear “yes” or “no.” So while I can’t tell you without taking a close look at your work and analytics, I can give you a few things to think about.
BUT FIRST, do you actually have a content strategy? I mean, do you have a documented plan that outlines what you’ll work on and what goals you’ll work towards for the next 3-6 months?
If not, you don’t really have a content strategy. Most of the companies I’ve ever worked with don’t have anything documented. I understand why. When there’s no documented strategy, you have flexibility. You aren’t really committed to any single thing. If something better comes up, you can pursue that instead. As you have cool ideas, you can pursue them.
Because I like running analogies, think about the difference between exercise and training. It’s possible to exercise a lot but never lose weight or get in better shape. For example, it’s really common that folks will work out too hard on a regular basis, rather than going hard on hard days and easy on easy days. This constant exertion and lack of focus means that athletes work hard but don’t progress.
A few years ago, when I got a running coach, he actually scaled back the hours per week that I ran. But he also brought structure and focus to my training. Hard days were hard, easy days were easy. We set A, B and C goals. We built an aerobic base, then layered on speed work as races got closer. Not surprisingly, it worked really well. I made progress in leaps and bounds, even though I wasn't working any harder than before. I had a goal and a plan to get where I wanted to go.
This is why you need a content strategy. It might feel uncomfortable to commit to a clear goal, but it will add shape and meaning to all the work that you do. You’ll have a way to say “no” to projects that would interrupt your progress and you’ll be able to build a narrative around the work you’re doing. (See Marketing to the organization)

Once you have a content strategy, there are a few ways to assess whether or not it’s working.
Content strategy is often deeply intertwined with product marketing, sales, go-to-market, demand gen, etc. It can be hard to even see what exactly is content vs. what is text that supports some other part of marketing. In general, look for progress. If you’re not improving at least every quarter, it’s time to re-evaluate.
