“It is important to consider what you are hoping to gain from the email, be that increasing sales, or letting your customers know about a new product, having the goal in mind will help you create content that encourages the reader to fulfill your call to action.”
Instead of sending an email because you have some content you think is interesting, ask yourself: who is my target audience, and what content appeals them? It’s not about your thoughts and feelings on content, it’s about theirs. If you don’t have a clear objective, you’re probably sending content your audience doesn’t want.
