The hook is the first line of your email after the closing. It determines whether your prospect reads on or closes the email. You have one sentence. Just one. It needs to show that you’ve done your research on them, not that you’ve just filled in a personalization field.
What Makes a Good Headline
A good opening line refers to the prospect in specific terms. Don't talk about their category ("sales managers in your industry"), but refer directly to them or their company.
It demonstrates keen observation. “I noticed that you’re hiring three SDRs this quarter” is a good opening line. “I’m sure you’re looking to grow your sales” is not.
It creates a natural sense of anticipation for what comes next. The prospect wants to know why you're bringing this up.
