There it is, staring at you from your inbox: “John, you’re going to love this deal.” You don’t know John. You are John. Or maybe you’re not. Either way, that subject line used your name. And just like that, you felt something—interest, curiosity, maybe even a little suspicion.
Personalization in email marketing has become the go-to trick to catch a reader’s eye. But here’s the real question: Does putting a first name in the subject line actually increase engagement? Or are we just flattering ourselves into lower open rates?
Let’s peel back the data, the psychology, and the strategy behind personalized subject lines—and figure out if the name-drop is still worth it in 2025.
Why Personalization Seems Like a No-Brainer
We get it. Everyone wants to feel seen. Our brains are wired to respond to our own names—just like we perk up when someone says “free tacos” or “limited-time offer.” Using someone’s name in a subject line should feel like you’re talking directly to them, not just firing another marketing blast into the void.
But it’s not 2012 anymore. Consumers are smarter. They know that email personalization is automated. The emotional impact of seeing “Hi {First Name}” has faded. And if it feels forced or gimmicky, it can backfire.
So does name-dropping still work? Sometimes. But not always for the reasons you think.
The Case for Using First Names in Subject Lines
When personalization works, it works because it feels natural—not because it’s simply there.
Pros of Name-Based Personalization
✔ Can boost open rates – Especially in first-touch campaigns.
✔ Grabs attention in crowded inboxes – Seeing your name makes a subject line pop.
✔ Creates an illusion of 1-to-1 communication – When done well, it mimics a personal message.
Cons of Name-Based Personalization
✖ Feels robotic if overused – “Sarah, we haven’t heard from you” just sounds automated now.
✖ Data mishaps = awkward moments – If your list isn’t clean, your subject could end up saying “Hi [FNAME]”. Not ideal.
✖ Can reduce trust – Some recipients view it as manipulative, not thoughtful.
The Case for Skipping the Name and Focusing on Value
Subject lines don’t need to be personal to be effective—they need to be relevant. In fact, some of the best-performing campaigns I’ve seen ignored first names altogether and instead nailed timing, tone, and clarity.
Pros of Name-Free Subject Lines
✔ Let the message do the work – Strong subject lines don’t need crutches.
✔ Less risk of creepy or incorrect personalization – No database error, no embarrassment.
✔ Feels more modern and direct – Short, punchy subject lines often perform better.
Cons of Skipping Personalization
✖ Can feel generic in crowded inboxes – You might blend in if the value isn’t clear.
✖ Harder to stand out in cold campaigns – If your brand isn’t known, personalization may help get a foot in the door.
What the Data Says About Personalization in Subject Lines
Let’s get nerdy. Studies show:
- Subject lines with a first name can increase open rates by up to 26%—but only when paired with relevant messaging.
- However, click-through rates often show no significant difference, meaning the email got opened… but didn’t necessarily convert.
- Emails with poor personalization (bad data, irrelevant offers) have higher unsubscribe rates than non-personalized emails.
The kicker? Context matters more than the name. If your offer is timely, your content is strong, and your audience is warm—personalization helps. If not, it can actually hurt.
Personalization Without Using a Name
Here’s the twist: you can personalize without ever using someone’s name. Segment your list. Reference past behavior. Speak directly to their problems or interests.
Examples:
- “Still thinking about that cart?”
- “This tool saved marketers 4 hours a week—yours next?”
- “You downloaded the guide. Now what?”
That kind of relevance hits harder than a first name ever could. And yes, Tarvent makes it easy to segment your audience and set up smart automation without making it feel robotic.
Top Email Marketing Tip: Personalization ≠ First Name
Here’s a hard-learned lesson: I once thought personalization meant dropping someone’s name into the subject and calling it a day. But after enough A/B tests, I realized names alone don’t drive engagement. Personalization is about relevance, not recognition.
With Tarvent, it’s simple to personalize based on what someone actually does—not just what their name is. Whether they opened, clicked, browsed, or bought, you can send emails that feel like you get them—no awkward name-in-subject required.
Conclusion
So, should you use a first name in the subject line? Sometimes. But don’t rely on it like a magic trick.
Use personalization when it adds value. Skip it when it feels forced. And remember—email marketing is about being helpful, not clever. A name might catch attention, but relevance earns the click.
If you’re serious about doing personalization right (without getting stuck in the "Hi {{First Name}}" trap), Tarvent gives you the tools to do it better—and smarter.
TLDR
- Using a first name in subject lines can boost open rates—but only when it feels relevant.
- Poor personalization can hurt trust and increase unsubscribes.
- True personalization = relevant content, segmentation, and timing.
- With Tarvent, you can personalize smarter—without relying on names alone.
