A coach with 480 subscribers, one lead magnet, and a $29 workshop doesn’t need the same email machine as a writer selling paid newsletters and evergreen courses.
I look at ConvertKit vs MailerLite as a stage problem, not a feature contest. Your list size, revenue path, automation needs, and tolerance for rebuilds decide the winner.
The wrong choice won’t just cost more. It can lock your system into the wrong shape before it starts.

ConvertKit vs MailerLite: The Short Answer
My rule is blunt: start lean with MailerLite.
Switch to ConvertKit when monetization complexity — not comparison anxiety — demands it.
Pricing verified against each platform’s official page: Kit pricing and MailerLite pricing. Monthly figures below scale with subscriber count.
How We Compared These Two
This isn’t a hands-on lab test.
It’s a research comparison built for one reader: a solopreneur choosing a first or second email platform while still holding a day job.
I read both platforms’ current pricing and feature pages, cross-checked them against independent Kit pricing breakdowns, and weighted the four things that change the decision at small scale: free-plan limits, the cost curve as your list grows, automation depth, and what you lose if you ever migrate.
I left out enterprise tiers, SMS add-ons, and anything a sub-10,000-subscriber creator won’t touch in year one. The goal is a clear pick by stage, not a feature checklist.
The Free Plan Trade-Off That Decides It for Most People
On paper, Kit’s free plan looks bigger: up to 10,000 subscribers, but only 1 automation, per its free Newsletter plan.
Kit’s free plan wins on subscriber count. Automation is the real limit.
That’s the trap. If you’re building a list from zero, subscriber count isn’t your first constraint.
The first constraint is whether every new subscriber gets:
- The right first email
- The right second email
- A clean path toward trust
The MailerLite free plan is smaller: 250 subscribers and 2,500 emails per month after the June 2026 change.
But it gives you full automation. That matters more when your list is tiny and every signup needs a welcome sequence.
So in the ConvertKit vs MailerLite free-plan decision, treat this as a workflow test, not a vanity-cap test.
MailerLite is the better free starting point if you need automation now.
Kit’s free tier makes more sense only if:
- You’re collecting names before building funnels
- ConvertKit monetization is already your next move
What Each Platform Actually Costs as You Grow
I’d treat pricing as a growth curve, not a monthly fee.
In 2026, Kit’s bill starts higher and climbs faster. MailerLite stays lean longer as your list moves from 1,000 to 10,000 subscribers.
Next, I’ll map the numbers so you can see when cost becomes the decision.
ConvertKit (Kit) Pricing in 2026
Kit’s Creator plan starts at $39/mo for 1,000 subscribers and scales by list size: $59 at 3,000, $89 at 5,000, and $139 at 10,000.
Creator Pro adds advanced reporting and subscriber scoring from $79/mo.
One detail catches people out. Prices rose roughly 35% in late 2025, so older guides quoting a $29 entry are stale.
There’s also a hard edge to the free plan.
The moment you cross 10,001 subscribers, the bill goes from $0 straight to $139/mo — no gradual ramp.
So in ConvertKit vs MailerLite, I’d only absorb this curve if tags, products, and paid newsletters justify the drag.
MailerLite Pricing in 2026
The plan split matters.
After June 2026, MailerLite renamed its tiers, so legacy guides using the old names are out of date.
The Comfort plan starts at $12/mo and covers most solopreneurs (formerly Growing Business). Power adds unlimited monthly emails and heavier automation for bigger lists (formerly Advanced).
That split gives you a practical choice:
- Lower-cost sending while your list is still growing
- Higher-volume features when your audience gets bigger
That’s the system advantage. You keep cash inside the project longer.
Your list gets time to prove it can earn before software turns into a fixed monthly drag.
Email Builder, Templates, and Design Flexibility
My stage-based take: design flexibility matters, but it’s not the main lever.
If you’re under 1,000 subscribers, builder speed helps. But free automation and monthly cost still decide the smarter starting point.
Kit leans text-first, with a lighter template library. MailerLite leans visual, with a fuller drag-and-drop editor. Neither gap is big enough to override price and automation at this stage.
Automation and Segmentation: Tags vs Visual Workflows
This is where the two platforms diverge most in ConvertKit vs MailerLite.
Kit organises everything around tags — flexible, behaviour-driven, but abstract at first. MailerLite organises around groups and visual workflows — easier to picture, faster to set up.
If you start simple, MailerLite is faster.
If tags become your growth system, Kit becomes the stronger long-term machine later.
Monetization: Selling Products and Paid Newsletters
Once you move from “grow the list” to “get paid,” ConvertKit (Kit) starts to pull ahead.
Its paid newsletters and digital product sales connect directly to subscriber behavior, with a creator commerce fee of 3.5% + $0.30 per transaction on every Kit plan, including free.
I’d treat this as the graduation point.
ConvertKit paid newsletters aren’t just a payment button. They can:
- Trigger tags
- Segment buyers
- Move a reader from free subscriber to customer
- Reduce the need for extra tools
Yes, MailerLite sells digital products too. That’s useful if you want simple checkout pages, file delivery, or paid access.
But Kit feels more native when the offer becomes the list’s core loop:
- Publish
- Charge
- Tag
- Follow up
- Upsell
Switching Costs: What Happens to Your List If You Leave
That’s the hidden switching cost in ConvertKit vs MailerLite.
A CSV can carry names, emails, custom fields, and maybe consent data. It won’t carry the decision tree:
- clicked link A
- joined group B
- skipped pitch C
- bought product D
That behavioral layer is exactly what makes an owned list valuable.
Kit founder Nathan Barry frames it simply: you get to “follow up with them on your schedule,” knowing what each subscriber bought, clicked, and ignored.
None of that intelligence rides along in an export.
I’d treat switching email marketing platforms like moving a store, not copying a spreadsheet. Inventory moves; shelves, signs, checkout rules, and customer paths get rebuilt.
In MailerLite vs ConvertKit, the model changes too. ConvertKit leans on tags; MailerLite leans on groups and segments.
Both can work. They just don’t translate cleanly.
Which One Fits Your Stage and Budget
I’d split this decision by stage, not feature count.
If you’re starting small or protecting cash, MailerLite fits the system. If you’re monetizing with products, paid newsletters, and deeper funnels, ConvertKit (Kit) starts to make sense.
Your budget isn’t just today’s price. It’s the cost of the list you’re building next.
Choose MailerLite If You’re Starting Out or Watching Costs
Choose MailerLite if you’re starting out or watching costs.
| Stage | Need | Pick logic |
|---|---|---|
| 0–250 subs | Welcome automation | Best free fit |
| 250–1,000 subs | Cheap growth | Controlled bill |
| Side hustle | Simple email loop | Fewer moving parts |
Across this comparison, MailerLite reads as the best free email marketing tool for building the habit before you buy complexity.
Choose ConvertKit (Kit) If You’re Monetizing at Scale
Choose ConvertKit (Kit) if you’re monetizing at scale.
- You sell offers. Paid newsletters, courses, downloads, and bundles. Tags connect purchase behavior to follow-up.
- You need deeper paths. ConvertKit automation can split readers by clicks, buys, interests, and intent.
- You’ve outgrown starter math. The free plan looks generous at 10,000 subscribers, but one automation caps the system.
If your list still needs cheap consistency, the MailerLite Comfort plan fits.
If your list funds the business, I’d pay for Kit and build around monetization, not comfort.
Frequently Asked Questions
Which Platform Has Better Deliverability for New Email Lists?
Like a clean runway, deliverability depends more on your takeoff habits than the airport.
For new email lists, it’s a practical tie. Both platforms can reach inboxes well if you follow strong sending practices.
Focus on:
- Using double opt-in
- Authenticating your domain
- Sending a welcome email quickly
- Avoiding cold imports
- Maintaining list quality
- Building engagement
- Keeping a consistent sending rhythm
If you’re starting from zero, platform reputation matters less than how clean, engaged, and permission-based your list is.
Can I Use My Own Domain for Landing Pages?
Yes, you can use your own domain for landing pages. But I’d treat it as a trust layer, not a growth lever.
You’ll usually connect a subdomain through your DNS settings, such as:
- pages.yourdomain.com
- go.yourdomain.com
I’d set this up before you:
- Drive paid traffic
- Share lead magnets
- Build a serious email list
It makes your links look cleaner, keeps your branding consistent, and helps you avoid looking temporary.
Do Either Tools Support SMS Marketing?
Yes, but don’t put the cart before the horse. I’d treat SMS marketing as secondary here.
MailerLite supports SMS in select cases through add-ons or integrations. It isn’t its core strength.
ConvertKit/Kit is mainly email-first. SMS is usually handled through connected tools like Zapier or dedicated SMS platforms.
If you’re building a small list, focus on email first:
- Set up your core email automations.
- Grow and segment your list.
- Add SMS later when revenue justifies it.
Which Integrates Better With WordPress and Shopify?
MailerLite integrates well with WordPress for most starters. Its forms, pop-ups, and ecommerce plugins feel straightforward to manage.
For Shopify, I’d give Kit the edge if you sell creator products and want purchases tied tightly to tags and email flows.
My quick take:
- If you’re running a content site first, choose MailerLite.
- If your store behavior drives the list, choose Kit.
- Pick based on where your revenue signals start.
Can I Run Multiple Newsletters From One Account?
Yes — you can run multiple newsletters from one account. I’d separate them using:
- Forms
- Groups/tags
- Segments
- Automations
The key risk: one misplaced segment can email 100% of your list by accident.
So structure matters more than the tool you choose. I’d create one audience database, then route readers by topic.
If each newsletter has different branding, cadence, or offers, I’d consider separate accounts before scaling.
Conclusion
I’d choose by system stage, not software hype.
Pick MailerLite when you need low cost, clean sends, simple sales, and room to learn. Pick ConvertKit when you need sharper tags, stronger funnels, and creator commerce, and can absorb the climb.
Test the free plan like a cockpit, not a showroom: click, build, break, measure.
Lists move, but workflows scar. Start lean, grow deliberately, and switch only when the machine you’ve built demands a larger engine.
Your next step is small: open the free plan that matches your stage, then wire up one welcome sequence this week.
If you want the bigger picture on turning that list into income, building traffic and an audience is the natural companion piece.
