If you run a one-person business, the MailerLite vs Mailchimp question comes down to something simple: Mailchimp is built (and priced) for marketing teams, and MailerLite is built for people like you.
That’s the short version. Here’s the evidence, so you can check my reasoning instead of taking my word for it.
The 30-second verdict
Pick MailerLite if you’re starting or growing a list under ~50K subscribers, you want automation without paying extra for it, and you’d rather your bill didn’t creep up every month. That’s most solopreneurs.
Pick Mailchimp if you genuinely need its 300+ integrations, deep segmentation, or revenue-attribution reporting — and you have the budget to pay roughly double for them.
Free plan face-off: this one isn’t close
Both tools have free plans. Only one of them is usable as an actual business tool in 2026.
| MailerLite Free | Mailchimp Free | |
|---|---|---|
| Subscribers | 500 | 250 |
| Emails per month | 12,000 | 500 |
| Automation | ✅ Included | ❌ Not included |
| Landing pages | ✅ | Limited |
| A/B testing | Paid tier | ❌ |
Read that middle row again. On Mailchimp’s free plan you get 500 sends a month — with 250 contacts, that’s two emails to your full list. MailerLite’s free plan gives you 12,000 sends, working automations, landing pages, and a website builder.
Mailchimp’s free tier has been trimmed so far down that it functions more like a 30-day trial. MailerLite’s free tier is something you can genuinely run a small business on for months.
For a solopreneur starting from zero, this row of the comparison ends the conversation. You’ll be on a free plan for a while — pick the one that’s actually free.
Pricing as your list grows: the gap widens
Free plans are the start, but the real cost question is what happens at 1,000, 5,000, 10,000 subscribers. As of mid-2026, the pattern looks like this:
- Around the 5,000-subscriber mark, MailerLite’s Growing Business plan runs about $39/month while a comparable Mailchimp Standard setup runs around $100/month.
- At 10,000 subscribers, Mailchimp costs more than double MailerLite for comparable functionality.
Two structural things drive the gap, and they matter more than the sticker prices:
1. Mailchimp bills you for dead contacts. Unsubscribed and duplicate contacts still count toward your Mailchimp bill. Someone leaves your list, and you keep paying for them until you manually clean house. MailerLite only charges for active subscribers. Over a couple of years, this quietly adds up to real money.
2. Mailchimp gates automation behind higher tiers. The welcome sequence — the single highest-ROI automation a solopreneur can build — requires a paid Mailchimp plan. MailerLite includes automation on every tier, free included.
Deliverability: the metric nobody markets
An email tool that lands in spam is worthless at any price. In independent deliverability tests, MailerLite has averaged around 94% inbox placement, while Mailchimp has been trailing in the low-to-mid 80s.
Deliverability numbers move around between test rounds, and your own sending behavior matters more than the platform’s average. But a persistent ~10-point gap is not noise — it means roughly one in ten of your emails going to spam instead of an inbox, before you’ve done anything wrong.
Where Mailchimp actually wins
An honest comparison has to include this part, because Mailchimp isn’t a bad product — it’s a mispriced one for this audience.
- Integrations. Mailchimp connects to 300+ apps. MailerLite’s integration list is much shorter. If your business runs on a specific stack (unusual CRMs, niche e-commerce platforms), check both integration directories before deciding.
- Advanced segmentation and reporting. Mailchimp’s behavioral segmentation, multivariate testing, and revenue attribution are genuinely deeper. Marketing teams use these daily. Most solopreneurs never touch them.
- Brand familiarity. Clients know Mailchimp. If you manage email for clients, that name recognition occasionally matters.
Notice the pattern: everything Mailchimp wins on is a team-scale need. If you read that list and felt nothing, you have your answer.
What switching actually looks like
If you’re already on Mailchimp: both platforms export/import contacts via CSV, and MailerLite has a guided Mailchimp import that preserves your groups as, well, groups. Budget an afternoon. The one real cost is rebuilding automations by hand — one more argument for switching before you’ve built twenty of them.
One honest caveat: MailerLite reviews all new accounts (usually within a day) before you can send. Mildly annoying, but it’s part of why their deliverability stays high — they keep spammers off the shared infrastructure.
The verdict
For a solopreneur in 2026, MailerLite is the better tool and it isn’t particularly close: a free plan you can actually operate on, automation at every tier, cleaner billing, stronger deliverability, and roughly half the price as you scale.
Choose Mailchimp only if you’ve looked at its integration directory or advanced reporting and identified a specific feature your business can’t run without.

FAQ
Is MailerLite really free forever? Yes, up to 500 subscribers and 12,000 monthly emails — no card required. You pay only when your list outgrows that.
Can I move from Mailchimp to MailerLite without losing my list? Yes. Export your Mailchimp audience as CSV (or use MailerLite’s built-in Mailchimp import) and your subscribers, groups, and fields come across. Automations must be rebuilt manually.
Which is easier for a beginner? MailerLite. Its editor and automation builder are simpler because there’s less enterprise machinery in the way. Mailchimp’s interface has grown dense as the product expanded.
Does either work with a static site (Astro, Hugo, plain HTML)? Both — embed forms or link out to hosted signup pages. MailerLite’s free landing pages are handy here: your signup page can live entirely on their infrastructure while your site stays static and fast.
