Brevo vs MailerLite: Sends vs Subscribers — Pick Your 2026 Weapon

Every few weeks, I get the same email from a founder or marketing lead: "We're done with Mailchimp. We've narrowed it down to Brevo and MailerLite — can you settle it?"

Fair question, because on paper these two look like twins. Both started as scrappy European SaaS underdogs. Both offer genuinely useful free plans. Both land in that $20–$120/month range where most growing teams actually live. And both will happily take your money and send your email.

But underneath the surface, they're built on opposite pricing philosophies — and that difference changes everything about how you'll use them.

The quick answer: If you have a modest list (under 25,000), send regularly, and care about design and inbox placement, pick MailerLite. If you have a large or messy database, need SMS or WhatsApp alongside email, or want transactional email infrastructure on the cheap, pick Brevo.

⚡ Quick Comparison Table

⚡ Feature-by-Feature Deep Dive

I compared seven areas that actually matter when you live inside an email tool for 40 hours a week. Here's how they stack up.

1. Contact Management & Segmentation

Brevo gives you unlimited contacts on every plan — including the free one. That's a legitimate superpower for businesses with bloated CRM data, imported spreadsheets, or big inactive lists they're slowly warming up. You get custom attributes, tags, segments, and a decent list-management UI. But it's clunky. Finding the right contact is a multi-click adventure, and the interface has a "grown by years of feature additions" smell. Some basic hygiene actions — like merging duplicates or building a suppression list — take more mental energy than they should.

MailerLite caps your contacts hard by tier, but the contact area itself is a joy. Groups and segments are clearly separated, the subscriber activity timeline is easy to read, and the UI is light and modern. Everything feels like it was designed in the last three years, because it was.

Winner: Brevo — for capacity, not experience. If your list is under 50,000 names, MailerLite's cleaner management wins on daily comfort. But unlimited contacts on a free plan is the sort of feature that saves real money when you're list-building from events, webinars, or multiple product lines.

2. Email Editor & Design

Brevo shipped a drag-and-drop editor years ago, and it's fine — like a rental car is fine. It gets you where you're going but nothing about the ride delights you. Templates cover the basics. Custom HTML is supported. It's functional, but when I put Brevo's output next to MailerLite's, the difference in polish is visible to any customer who looks.

MailerLite has the best email editor in this price bracket, full stop. The drag-and-drop grid is fast, the templates are modern and conversion-focused, and the free-form "rich text" block gives designers near-total control without writing code. Agencies build entire client systems on MailerLite and never touch HTML. This is MailerLite's crown jewel, and it's why many people swear by it.

Winner: MailerLite. Not close.

3. Marketing Automation

Brevo's automation builder is genuinely powerful. You can build visual workflows with email, SMS, and WhatsApp branches, attach conditionals, set up A/B tests, and trigger flows from transactional events. Want a cart-abandonment flow that sends WhatsApp after two emails and an SMS on day three? Brevo does that natively. The tradeoff: the builder takes a weekend to master, and power features like send-time optimization hide behind higher tiers.

MailerLite keeps automation simple. The classic builder handles welcome sequences, nurture tracks, and win-back campaigns with conditional branching. Their newer "customer journey" builder adds visual power without the learning cliff. But it's email-only. No SMS. No WhatsApp. For pure email automation, it's faster to ship and easier to maintain.

Winner: Brevo on raw capability; MailerLite on usability. If I have to pick one for the round, I'm giving it to Brevo only if you need multi-channel journeys. For standard email nurturing — which is what 90% of teams actually need — MailerLite is the better daily driver.

4. Deliverability & Sender Reputation

Brevo runs on solid AWS infrastructure, but its free plan means anyone can spin up sending — which makes shared-IP reputation a shared-risk game. Many users report great inboxing; others report sliding into promotions tabs or spam after a single complaint spike. Brevo does offer dedicated IPs on higher tiers, and you should absolutely set up DKIM/SPF from day one. But you'll be actively managing your reputation rather than assuming good behavior.

MailerLite has a long-standing reputation for strong deliverability. They enforce double opt-in by default, care about list hygiene with a gentle but firm hand, and their support team actively monitors sender behavior. Their stance is that shared IPs work fine when the sender follows the rules — and the G2 review pattern backs that up. If you're coming from a tool that gave you spam-folder nightmares, MailerLite is the safer landing spot.

Winner: MailerLite, and deliverability risk is exactly the kind of thing that's hard to measure until it's too late.

5. Landing Pages & Lead Capture

Brevo includes a form builder and landing pages, but "included" is the appropriate word. Templates are limited, the editor feels spare, and you won't mistake a Brevo landing page for a Unbounce page. If your only need is a simple "subscribe to our newsletter" page, it's fine.

MailerLite treats landing pages as a first-class feature. You get 40+ sharp templates, fast rendering, custom domains, popups, embedded forms, and a surprisingly capable mini website builder. For early-stage companies that don't want to pay for a separate landing-page tool, MailerLite genuinely covers that job.

Winner: MailerLite.

6. Reporting & Analytics

Brevo reports cover the essentials — opens, clicks, unsubscribes, engagement over time — and they're better than what you'd get in the old Sendinblue days. If you also use Brevo's transactional email or SMS, you get the rare benefit of all delivery data in one dashboard. But the presentation is utilitarian. Don't expect to wow an executive with a pretty report.

MailerLite gives you clean, scannable insights: a visual open-and-click breakdown, revenue attribution tracking on the Advanced plan, A/B test summaries, and even unsubscribe-reason capture. It's simpler data, but you'll actually read it. For most teams, that's more valuable than more data.

Winner: MailerLite for day-to-day reporting. Brevo if you're an ops person who needs transactional + marketing stats under one roof.

7. Multi-Channel & Developer Tools

Brevo is a different animal here. Native SMS, WhatsApp, web chat, transactional email via SMTP or a real REST API (roughly 10 requests/second by default, expandable), webhooks, SDKs, and 100+ native integrations. If you're an ecommerce team that needs order confirmations, or a platform that sends password resets, Brevo is genuine email infrastructure dressed in marketing clothing.

MailerLite has a perfectly good API for managing subscribers and triggering campaigns, and its Zapier integration covers most gaps. But there's no transaction SMTP relay and no SMS. It's a marketing tool, not a delivery platform.

Winner: Brevo, by an enormous margin.

Scorecard so far: Brevo takes contact capacity, automation power, and multi-channel/dev. MailerLite takes design, deliverability, landing pages, and reporting clarity. The right choice comes down to which three matter more to your business.

⚡ Pricing Face-Off

This is where the two tools stop being comparable and become a real fork in the road.

Brevo prices by email volume (with unlimited contacts). MailerLite prices by subscriber count (with essentially unlimited sends on paid tiers). Approximate annual-billing prices, as of Q3 2026:

The pattern is clear. MailerLite wins when your list is small-to-mid and you send often. Brevo wins when your list is large or dormant and you send rarely.

One hidden Brevo cost: transactional emails count against your volume. If you're sending automated receipts plus campaigns, your volume burns faster than you expect. Conversely, MailerLite's "unlimited sends" have a fair-use policy — roughly 12x your subscriber count per month in practice. If you're emailing your 10,000-subscriber list 15 times a month, you'll feel the soft limit. Read the fine print.

⚡ Integration Ecosystem

Brevo has become a credible hub in its own right: native integrations for Shopify, WooCommerce, WordPress, Salesforce, HubSpot, Stripe, and Zapier/Make for the long tail. On the API side, Brevo is genuinely developer-friendly — it's the only tool in this comparison that you could also build a SaaS product on, thanks to SMTP relay and transactional triggers.

MailerLite ships with fewer native connections, but the important ones are there: Shopify, WooCommerce, Squarespace, Wix, WordPress, Stripe, Zapier, Make. For most marketers, Zapier fills every remaining gap in an afternoon. The limitation is architectural: because there's no deep SMS or transactional engine, the integrations only do "marketing email" things.

Winner: Brevo. But be honest with yourself — if you're not building automation with code, this advantage is theoretical. A Zapier connection in both tools will feel equal.

---

⚡ User Experience & Learning Curve

Brevo wants to be an all-in-one CRM: email, chat, SMS, WhatsApp, sendinblue-style pipelines, all in one place. Great if you want consolidation. Bad if you want simplicity. New users typically spend a weekend feeling lost, then settle into a rhythm. The dashboard pushes notifications at you; the AI-writing assistant in the editor is optional but handy; the overall aesthetic is "enterprise tool that got a paint job." Expect a week before your team is fully productive.

MailerLite gets you from signup to sent campaign in under 20 minutes. The navigation is minimal: dashboard, campaigns, automation, subscribers, landing pages, forms. A non-technical founder can learn it without a tutorial. The biggest "training" challenge is convincing your team that things are allowed to be this easy.

Winner: MailerLite. Unless your team lives in Brevo's CRM and you need that connective tissue, MailerLite's simplicity is more valuable than Brevo's sprawl.

⚡ Who Should Pick Brevo?

Brevo is your tool if any of these describe you:

• You have a big, messy list. 100,000+ contacts collected over years, or a CRM export you haven't cleaned. Brevo's unlimited contacts mean you can import everything without your bill doubling. MailerLite would charge you a rent payment for that list.
• You run ecommerce with transactional needs. You need order receipts, abandoned-cart emails, and shipping notifications — and you'd rather pay one vendor than stitch together SendGrid + Mailchimp.
• SMS or WhatsApp is part of your strategy. This is increasingly true for LATAM, European, and Asian businesses. Brevo's native SMS and WhatsApp nodes in automation are miles ahead of anything MailerLite offers (which is nothing).
• You're a developer or ops person. Brevo's API and SMTP relay mean a developer can build real product notifications without adopting a separate infrastructure tool.

Scenario: A 30-person D2C brand with 80,000 contacts, sending weekly campaigns plus order confirmations, plus WhatsApp abandoned-cart flows. Brevo is the rational choice — MailerLite's list-pricing would eat them alive and MailerLite can't reach their customers' phones.

⚡ Who Should Pick MailerLite?

MailerLite is the better pick if:

• You're a newsletter publisher or content creator. Your list is 1,000–40,000 people, you send weekly, and your product is your writing and design. MailerLite's editor will make you look professional with half the effort.
• You send frequently to a modest list. If you're emailing every day or multiple times a week, MailerLite's flat subscriber pricing is dramatically cheaper than Brevo's burn-by-volume model.
• You've been burned by deliverability. If your previous tool landed you in spam, MailerLite's hygiene defaults and solid reputation give you the best shot at a clean recovery.
• You're an agency. The editor speed, template quality, and simple client onboarding make MailerLite a favorite of small agencies managing multiple brand newsletters.

Scenario: A 6-person B2B consultancy with 8,000 subscribers, sending a weekly insight newsletter plus a monthly client update. They want beautiful emails, no SMS, no code, no fuss. MailerLite costs ~$30/month and pays for itself on the first design win.

⚡ The Verdict

Here's how I'd actually advise a friend (and several of you reading this).

If you're a typical small-to-mid business (under 25,000 contacts, sending 2+ campaigns per week), MailerLite is the better default. Better editor, better deliverability, simpler pricing, less time on-leash with support. It's the tool I'd hand to a marketer who just wants to send great email without a weekend of onboarding.

If your database is large, your send frequency is low, or your strategy includes SMS/WhatsApp/transactional email, Brevo is the only rational choice. MailerLite would penalize you for list size with no path to multi-channel at all. Brevo's volume-based model turns your biggest asset into your cheapest send.

The tie-breaker is simple: pick the pricing model that punishes the behavior you least want to be punished for. If you have 80,000 contacts and send monthly, Brevo. If you have 8,000 contacts and send daily, MailerLite. Your list size isn't just a number — it's the whole ballgame.

⚡ FAQ

1. Can I migrate my subscribers from Brevo to MailerLite without losing data?

Yes. Both tools support CSV import. Export your Brevo contacts, upload them to MailerLite, and re-map custom fields. The bigger lift is rebuilding automations — workflow logic doesn't transfer cleanly, so budget an afternoon to recreate your welcome and nurture sequences.

2. Does Brevo's free plan really allow unlimited contacts?

It does. You're capped at 300 emails per day (about 9,000 per month), which is roughly enough for a very small business or a hobby newsletter. MailerLite's free plan gives you 1,000 subscribers and 12,000 emails per month. The winner depends on whether you have more contacts (Brevo) or need more sends (MailerLite).

3. Which tool has better deliverability in 2026?

MailerLite, based on consistent user reports across G2 and Capterra. Its double opt-in default and list-hygiene focus matter. Brevo can deliver fine — especially with warmed dedicated IPs on higher tiers — but it requires more active management.

4. Does either tool offer SMS or WhatsApp marketing?

Only Brevo. It bundles SMS credits and WhatsApp messaging into its plans and automation builder. MailerLite is email-only (with landing pages and forms). If mobile channels are a must, MailerLite is out of the conversation entirely.

5. What if I have 200,000 contacts but only send a monthly newsletter?

Brevo wins by a landslide. At roughly 10,000 emails per month, you'd pay around $25–30/month on Brevo's Starter tier. MailerLite's subscriber-based pricing would push you into the hundreds of dollars per month. This is exactly the scenario Brevo's unlimited-contact model is designed for.

6. Which tool is better for an agency managing five client accounts?

MailerLite. The speed of the editor, the clean client-facing reports, and the flat pricing make multi-account work far less painful. Brevo is powerful, but you'll spend more time inside its automation builder and CRM-like UI for each account.
