Your First Two Lines Now Decide Everything
Picture this. You spend an hour on your newsletter. You pick the perfect story, you sharpen every line, you fuss over the subject line until it feels right. You hit send and you feel good about it.
And then your reader opens Gmail, sees a two-line AI summary sitting under your subject line, and decides whether you were worth their time in about a second. They never even scroll to the part you worked so hard on.
That little window at the top of your email used to be a nice-to-have. Now it's carrying your whole send. So let's talk about how to write it.
Why Your Opening Lines Suddenly Matter This Much
If you've been following along, you already know Gmail rolled out AI summaries to its three billion users. I broke down the full picture in this piece on what the AI inbox means for your newsletter, and it's worth a read if you missed it.
Here's the one detail that matters most for today. The AI pulls most of its summary from the first 100 to 200 characters of your email. That's roughly your first sentence or two.
So whatever you put up top is what the AI grabs, condenses, and shows to your reader before they decide to open. If those first lines are strong, the summary works in your favor. If they're a throat-clearing hello, the summary has nothing good to pull, and your reader scrolls right past.
The Mistake Almost Everyone Is Making
Most of us were taught to open warm. So we start with something like, "Hey friend, hope you had an amazing weekend. I've been thinking a lot about this lately and wanted to share."
It feels kind. It feels personal. And it tells the reader absolutely nothing about why they should keep going.
When the AI summarizes that, it has nothing to work with, so it either grabs the weak opener or it digs deeper and decides for itself what your email is about. Either way, you've handed control of your first impression to a machine, and you've spent your most valuable real estate saying hello.
I get why we do it. Cold openers feel pushy. But there's a way to lead with substance and still sound like a warm human, and once you see it you can't unsee it.
What a Strong First Two Lines Actually Do
You don't need a copywriting degree for this. You just need to do three things in your opening, and you can do all three in a sentence or two.
Lead With What They Get
Open with the payoff. Tell the reader the most useful or interesting thing in the email right away, the way you'd blurt out the best part of a story to a friend before you even sat down. If your issue is about pricing, don't ease in with "today let's talk about pricing." Tell them what they're about to figure out about their own pricing.
Be Specific Enough to Be Believed
Vague openers get vague summaries. "Some thoughts on growing your list" is forgettable. "The list-building tactic I dropped last year and finally picked back up" is a real thing a real person would open. Specifics signal that there's something here a summary can't fully replace, which is exactly the impression you want.
Leave a Loop the Summary Can't Close
This is the one that protects your open rate. Tease the answer without handing it over. If the whole point of your email fits neatly into two lines, the AI will deliver it and your reader is done. So promise the payoff, but make them open to actually get it. Curiosity is the one thing a summary can't satisfy on your behalf.
Let's Make This Real
Here's how this looks when you put it side by side. Same email, two different openings.
"Hi friend! Hope your week is off to a great start. Today I want to chat about why your digital products might not be selling the way you'd hoped."
"The reason your $47 product isn't selling has almost nothing to do with the price. I figured this out the hard way last month, and the fix took me about ten minutes."
See the difference? The first one warms up and tells the AI nothing. The second one promises a specific payoff, sounds like a real person, and leaves you wanting the ten-minute fix. A summary of that second opener still makes you want to open, because the actual answer isn't in there.
And notice that the strong version is still warm. It still sounds like me talking to you. Leading with value doesn't mean turning into a cold robot. It just means respecting that your reader is busy and giving them a reason to lean in before you settle into the hello.
"Write your opening like the AI is going to read it out loud to your reader. Because most days, that's exactly what's happening."
Dr. Destini CoppA Two-Minute Test Before You Hit Send
Here's a quick habit that'll save you. Before you schedule your next issue, read only your first two lines out loud. Pretend that's all you get to show someone. Would they open?
If the answer is "eh, maybe," rewrite it. And if you want to really see what your reader sees, paste your draft into a free AI tool and ask it to summarize the email in two lines. Whatever it spits back is close to what's landing in the inbox. If that summary gives away the whole thing, tighten your loop. If it sounds flat, your opener needs more specificity.
This isn't busywork. It's the highest-leverage two minutes you'll spend on the whole email, because it's the part that decides whether the rest gets read at all.
This Is a Skill, and You Can Build It
If writing openers like this feels hard at first, that's normal. We spent years training ourselves to warm up before we got to the point. Unlearning that takes a few reps.
But it's a muscle, and it gets easier fast. After a handful of issues you'll start drafting the payoff first out of habit, and your open rates will tell you it's working. This is one of the core skills I walk creators through inside Newsletter Profit Club, because strong openers are where a profitable newsletter actually begins.
Start with your very next send. Write the payoff first, get specific, leave them a reason to open, and let the warm hello come second. Your reader, and the AI standing between you and them, will both thank you.

Gmail's AI pulls most of its summary from the first 100 to 200 characters of your email. That means your opening lines are now what most readers see before they decide whether to open. If those lines waste space on a greeting, the AI summary has nothing strong to work with and your reader moves on.
Lead with the payoff. Tell the reader exactly what they will gain or learn, and be specific about it. Skip the warm-up greeting and open the way you would if you were telling a friend the most interesting part of a story first.
Get to the point inside the first 100 to 200 characters, which is roughly the first sentence or two. That is the window the AI reads most closely and the window a busy reader scans. Save the warm hello for after you have given them a reason to keep reading.
Set up a test inbox and watch how your sends render in the summary line. You can also paste your draft into a free AI tool and ask it to summarize the email in two lines. If that summary gives away everything, your opening is too complete and needs an open loop.
You can, but not in the first line. Personal warmth still builds connection, so keep it. Just earn the open first by leading with something the reader cares about, then bring in the friendly hello once they are already reading.
