"Hi [First Name]" stopped working somewhere around 2015. Everyone does it, everyone knows how it is done, and no subscriber has ever felt recognised by it.
The instinct when click-through rates stall is to look for a tool. But most of what improves click-through costs nothing, and the paid options work considerably better once the free things are already in place. So this is ordered by cost, starting at zero.
Free: send less email to fewer people
The least intuitive fix, and usually the largest.
Click-through rate is clicks divided by opens. Sending a broad campaign to your whole list depresses that ratio structurally, because most recipients were never going to click - the content was not for them.
Cutting a send to the segment it is actually relevant to typically lifts click-through immediately. Not because anything improved, but because you stopped counting people who had no reason to act.
This matters beyond the metric. Deliverability rewards engagement, so sending relevant email to smaller groups tends to improve inbox placement over time, which lifts everything else.
What to do: take your next campaign and ask who it is genuinely for. Send it to them. Resist the temptation to include everyone because the list is there.
Free: personalize what you send, not just how you greet
Most "personalization" is a name in a greeting. The version that changes behaviour is choosing what to send based on what someone did.
Using only data you already have:
- Last product viewed or purchased - the basis of every recommendation email that works
- Where someone is in onboarding - people at step two need different content from people at step seven
- Engagement recency - a subscriber who opened three of your last four emails should not receive the same message as one who has not opened since January
- What they signed up for - if they came in through a specific lead magnet, that tells you what they care about
None of this needs new software. It needs the segmentation your email platform already includes.
Free: make the subject line specific rather than personal
Putting the name in the subject line is now so common it reads as automation rather than attention. Specificity outperforms it.
"Sarah, check out our new features" is personalized and vague. "Three things changed in the reporting dashboard" is impersonal and specific. The second gets opened by people who care about reporting, which is exactly who you want opening it.
The same applies to preview text, which is under-used and free.
Free: fix the obvious mechanical problems
Worth checking before optimizing anything:
- One clear call to action. Emails with five competing links dilute clicks across all of them.
- Buttons that work with images blocked. If your CTA is an image and Outlook blocks it, that recipient sees nothing to click.
- Mobile rendering. Most opens are on phones. A CTA that requires precise tapping loses clicks silently.
- Link placement. Something clickable above the fold, and again at the end.
These are not glamorous and they routinely account for more lost clicks than any personalization strategy would recover.
Nearly free: send at a sensible time for each person
Most platforms include send-time optimization on standard plans. It costs nothing extra and it moves opens, which moves clicks.
Even without that feature, sending at a time that suits your audience rather than a time that suits your calendar is free.
Low cost: personalized images
This is where a small amount of spending starts to earn its place, and it is the step most teams skip straight to - which is why it is here rather than at the top.
An image showing the recipient's name, their company, or the product they were looking at is visual rather than textual, so it is not subject to the fatigue that made "Hi First Name" invisible. It is also difficult to fake, which is precisely why it reads as effort.
The reason it is affordable is that the work is fixed regardless of list size. You build one template with placeholder fields, and each recipient's email renders their own version from data you already hold. There is no per-recipient design work, so the cost does not scale with your audience.
Where it earns most:
- Welcome emails, where attention is highest
- Abandoned cart, showing the actual item rather than a generic reminder
- Win-back, where the audience is disengaged and something different is needed
Worth being honest about the size of the effect: it varies enormously by audience and use case, and anyone quoting you a specific percentage is guessing. We wrote about how to measure it properly on your own list rather than trusting a benchmark.
Low cost: behavioural triggers using data you already have
Triggered emails outperform campaigns consistently, because they arrive when someone has just done something relevant.
The ones worth building first, roughly in order of return:
- Abandoned cart or abandoned form
- Post-purchase or post-signup follow-up
- Re-engagement after a period of inactivity
- Milestone or anniversary
Most email platforms include automation on mid-tier plans. If yours does, this costs time rather than money.
What not to spend money on first
Being direct about this, because the sequence matters more than the tools:
Do not buy an enterprise personalization platform to fix a click-through problem caused by sending everything to everyone. It will not fix it and it is expensive.
Do not buy AI copywriting before you have worked out what to say. Faster production of the wrong message is not an improvement.
Do not switch email platforms hoping it will help. Migration is expensive in time, and the platform is rarely the bottleneck. If your current tool does segmentation and automation, it is probably adequate.
Do not buy more data before using the data you have. Most teams are not using half the fields already in their platform.
A sensible sequence on a limited budget
If you are starting from generic sends to a whole list:
- Segment the next campaign and send to who it is for. Free, immediate.
- Fix the mechanical issues - one CTA, works without images, readable on mobile. Free, one afternoon.
- Build one triggered email - abandoned cart or welcome. Usually included in your plan.
- Make subject lines specific rather than name-personalized. Free.
- Add personalized images to your highest-value flow, not to everything. Small cost, measurable.
- Measure properly before spending more.
Most teams get meaningful improvement from the first four, which cost nothing but attention.
Measuring it without a budget
You do not need analytics software to know whether this is working.
Run one thing at a time and compare against your own recent baseline. Change the segmentation, hold everything else, look at the result. Then change something else. Sequential single changes are slower than a proper test framework but they are free and they are honest, provided you resist changing three things at once and claiming the win for your favourite.
For anything you intend to keep, run a proper A/B split - every major platform includes one.
Frequently asked questions
How can I improve email click-through rates without spending money? Segment your sends so each campaign goes to people it is relevant to, personalize what you send rather than just the greeting, make subject lines specific rather than name-based, and fix mechanical problems like multiple competing calls to action or CTAs that vanish when images are blocked. These are free and typically account for more improvement than paid tooling.
Why has "Hi First Name" stopped working? Because it is universal. Every sender does it, subscribers have seen it for over a decade, and it demonstrates only that you have a database. It is not harmful, it is simply invisible.
What is the cheapest personalization that actually changes behaviour? Choosing what to send based on what someone did - last product viewed, onboarding stage, engagement recency. This uses data you already hold and segmentation your platform already includes.
Are personalized images expensive? Less than most people assume, because the work is fixed at one template regardless of list size. There is no per-recipient design work, so cost does not scale with audience. It is worth doing after the free improvements rather than instead of them.
Should I switch email platforms to improve click-through? Rarely. Migration costs significant time and the platform is seldom the bottleneck. If yours supports segmentation and automation, it is probably adequate for everything in this article.
How do I know which change actually helped? Change one thing at a time and compare with your own recent baseline, or use your platform's built-in A/B split. The common mistake is changing several things at once and attributing the result to whichever you were most enthusiastic about.
How much lift should I expect? Nobody can tell you honestly - it depends on your baseline, audience and industry. If your click-through is currently 1% there is room to move; at 8% you are already doing most things right. Measure against your own history rather than a published benchmark.
What is the single highest-return change? Sending less email to more relevant people. It is free, it lifts click-through immediately, and it improves deliverability over time.
Start with the free ones
If click-through has stalled, the useful first move is not buying anything. Take your next campaign, cut the audience to who it is genuinely for, give it one clear call to action, and see what happens. That costs an afternoon.
When you are ready to add a paid layer, personalized images are a sensible one - the cost is fixed at one template no matter how large your list, and it addresses exactly the fatigue that made name personalization stop working.
