If you have a business, chances are that you’re sending marketing emails. If you aren’t, you probably should be.
The beauty of email marketing is that you own the list of contacts that are on it. You aren’t at the mercy of social networks who own your audience and can change or even deny you access at any time.
It’s your list and you can do what you want with it.
But, if you are emailing your list, you have to make it count. People have signed up because they want value from it so make sure you’re delivering that in the emails you send.
