The single biggest mistake you’re making in your marketing emails is starting every sentence with, “I.”
It’s not about you. It’s about them.
Your email shouldn’t about what you want or need. It’s should be about what you can do for them.
What problem(s) will you solve for them?
How will you make their life easier?
How will you make their business better?
You’ve got a couple of sentences to convince them you can solve their problems and/or make their lives easier.
Compose your email from their perspective. Not from yours.
