Ahoy, Digital Writers!

Today we are going to ask ChatGPT to help us write email subject lines that lead to higher open rates.

If you are writing an email newsletter, sending marketing emails, or communicating with your boss at work, it’s important to understand how your content is going to arrive in someone’s inbox.

Let’s take a look.

• The first part is the Subject Line. This is the bolded sentence you read first when you see an email arrive. It’s the hook.

• The second part is the Subtext Line. This is the grey sentence you read second, usually giving a bit more context as to what is “inside” the email—so someone knows what they’re about to click on. It’s like a “Whisper” to the reader. “Hey… pssst…. here’s what’s inside” sentence.

Nailing the combination of the Subject and Subtext is the difference between a 45% open rate and 5% open rate. And if you a follow a few simple rules and enlist the help of ChatGPT, you’ll have everything you need to fire off an irresistible email today!

Which leads us to Rule #1.
