Final thoughts
We can spot quite a few trends when we look at these email marketing statistics.
The first is that email marketing is still a popular form of marketing, especially when it comes to promoting content.
We can also see that segmentation is one of the best email marketing strategies you can use yet most email marketers don’t use it or don’t use it properly.
We can tell by the way most email marketers struggle to stand out in the inbox as well as how low the average open and click-through rates are.
We highly suggest getting to know your email marketing service provider’s platform better or switching to an email service that offers better email building and segmentation features than your current provider.
With that said, that wraps up our roundup of the latest email marketing statistics.
