If you have narrowed your email-marketing shortlist to MailerLite and Brevo, the most useful question is not which homepage shows the lower starting price. It is whether your list size and sending pattern fit the limits behind that price.
Brevo can be unusually attractive when you keep a large contact database but send relatively little, especially if no single day needs more than 300 recipients. MailerLite can become more relevant when your sending pattern, same-day campaign size or team requirements push you beyond that Brevo Free boundary.
Neither is the universal winner. The answer changes with measurable requirements.
Scope: marketing and newsletter email only
This guide compares MailerLite and Brevo for recurring marketing and newsletter email. It is not an SMTP, API or app-triggered transactional-email comparison.
It is also not a ranking of the whole email-marketing market. ChoiceSpec's calculator currently covers five providers: MailerLite, Brevo, Kit, beehiiv and Systeme.io. This article explains the MailerLite-vs-Brevo trade-off; the calculator handles exact personalised plan fit across all five.
The short answer
Start with Brevo when a large stored list and low, spread-out sending are the unusual part of your setup. Brevo Free currently allows up to 100,000 stored contacts, but it limits sending to 300 emails per day and includes one seat.
Start by checking MailerLite when your list is small enough for its tiers but your sending frequency, same-day campaign needs or number of users make Brevo’s Free limits awkward. As of Aug 23, 2026, MailerLite Free allows up to 250 subscribers, 2,500 emails per month and two seats.
Put those numbers together: if your list is 250 subscribers or fewer, compare the free plans on seats and sending frequency. If it is over 250, MailerLite Free is out, so Brevo Free remains possible only if your sending pattern stays within 300 emails per day and one seat.
Once either free plan stops fitting, do not decide from the headline starting prices alone. MailerLite’s paid plans have subscriber-tier and plan-specific sending rules, while Brevo’s paid pricing varies by its own send and contact tiers. Exact paid economics are dynamic enough that they belong in the calculator, not in a fixed article verdict.
Why the pricing models behave differently
It is tempting to summarize the comparison as “MailerLite charges by subscribers; Brevo charges by sends.” That is useful shorthand, but it is too simple to make a buying decision.
MailerLite is strongly subscriber-tiered, but sending limits also matter. Its Comfort plan starts at $12 per month, includes three seats and gives a monthly send allowance equal to 10 times the purchased subscriber-tier ceiling. Power starts at $25 per month and includes unlimited monthly emails and unlimited seats.
Brevo lets its Free users store far more contacts, but Free is constrained by the 300-emails-per-day limit and one seat. Starter starts at $9 per month and removes the daily-send limit; Standard starts at $18. Above the entry point, exact pricing depends on the tier combination rather than one simple flat comparison.
So the real decision has several axes: how many people are on your list, how many emails you send in a month, how many recipients you need to reach on your busiest day, and how many people need access to the account.
The free-plan boundary is unusually important
The two free plans behave very differently.
MailerLite Free: up to 250 subscribers, 2,500 emails per month and two seats.
Brevo Free: up to 100,000 stored contacts, 300 emails per day and one seat.
That creates situations where Brevo can fit a surprisingly large database for $0, while MailerLite can fit some small-list cases that Brevo Free rejects because of its one-seat limit.
A small-list case where both can fit
Imagine you have 200 active subscribers, send about 1,000 marketing emails a month, never need to reach more than 200 recipients in one day, and only one person uses the account.
On the limits above, both free plans can fit that basic scenario.
That is a useful result in itself. There is no reason for this article to invent a winner when the measurable requirements do not separate them. If both remain eligible at $0, the final choice may depend on preferences or capabilities this comparison does not score.
A large-list, low-send case where Brevo stands out
Now imagine you have 20,000 contacts, send about 6,000 marketing emails per month, keep every sending day at 300 recipients or fewer, and only one person needs access.
Brevo Free can fit that pattern: the stored list is below 100,000 contacts, the one-seat limit is fine, and the daily sending pattern stays inside 300.
MailerLite Free fails immediately because 20,000 subscribers is far above its 250-subscriber limit.
This is the clearest reason not to judge the pair from list size alone. A large database does not automatically mean a large Brevo bill if your actual sending is light and segmented enough to stay within the Free daily cap.
The 300-recipient day is a hard Brevo Free boundary
Change only one thing in that 20,000-contact example. Suppose you still send roughly 6,000 emails per month, but one campaign needs to reach 2,000 people on the same day.
Brevo Free no longer fits because the same-day send is above 300.
That does not mean MailerLite suddenly wins. With a 20,000-person list, MailerLite Free also fails, so both options have moved into paid-plan territory. The correct comparison now depends on current subscriber tiers, send allowances and Brevo’s dynamic paid pricing.
This is where a static “Brevo is cheaper” or “MailerLite is better for frequent senders” rule becomes unreliable.
Seats can flip the free-plan answer too
Consider a much smaller list: 200 subscribers, around 1,500 marketing emails per month, no more than 200 recipients on the busiest day, but two people need access.
MailerLite Free can fit those headline requirements because it currently includes two seats.
Brevo Free includes one seat, so it fails that team requirement even though the contact and sending limits would otherwise fit.
Again, this is not a claim that MailerLite is better for teams in general. It is one objective boundary at the free-plan level. As team size grows, paid-plan rules and prices matter, and the comparison becomes dynamic again.
When Brevo is the stronger pairwise starting point
Brevo is especially worth checking first when your business has a large stored list but sends to relatively small segments, sends infrequently, can keep every sending day within 300 recipients, and only needs one user.
That pattern is common enough to matter because contact storage and sending activity are not the same thing. A business may keep thousands of leads, past customers or segmented contacts without emailing all of them every week.
If that is your setup, Brevo Free can remain eligible in situations where MailerLite Free cannot.
When MailerLite becomes more relevant
MailerLite becomes more relevant to check as the constraints shift away from “large list, light sending” toward higher send frequency, larger same-day campaigns or additional users.
The important word is “check.” It is not safe to turn that into a blanket rule that frequent senders should always choose MailerLite.
MailerLite Comfort still has a tier-linked monthly send ceiling. Power changes the economics by allowing unlimited monthly sends and seats. Brevo’s paid plans remove the Free daily-send gate, but their pricing varies by the selected send and contact tiers.
Once you are paying, the answer can move as your numbers move. A fixed crossover published in an article can become wrong when either provider changes a tier.
Do not compare the $9 and $12 starting prices as if they are equivalent
Brevo Starter currently starts at $9 per month. MailerLite Comfort starts at $12.
Those figures are useful for orientation, but they are not a like-for-like verdict. The plans are governed by different subscriber, send, seat and packaging rules, and higher paid tiers can change with the inputs.
The same caution applies to Brevo Standard from $18 and MailerLite Power from $25. Starting prices tell you where a plan family begins; they do not tell you what your business will pay.
That is why this article uses starting prices only for context and sends exact paid-plan crossover work to the calculator.
Transactional email is a separate buying decision
Brevo also offers transactional email. MailerLite directs transactional-email needs to its separate MailerSend product.
That difference may be important if you are choosing infrastructure for password resets, receipts, account notifications or other SMTP/API/app-triggered messages, but it is outside this comparison.
Do not use the MailerLite-vs-Brevo conclusions above to choose a transactional-email platform. The requirements, products and pricing logic are different enough to deserve a separate decision.
What this pairwise guide cannot decide
Even if MailerLite and Brevo are the two names on your shortlist today, neither has to be the final ChoiceSpec result.
The email-marketing calculator also covers Kit, beehiiv and Systeme.io. Under the same subscriber count, send volume, campaign size, user count and branding requirements, one of those providers may fit at a lower verified monthly price, or more than one provider may tie.
The article therefore has a narrower job: explain why the MailerLite-vs-Brevo answer changes.
The calculator has the broader job: apply your actual inputs across all five covered providers and identify the lowest-cost covered monthly plan that fits where exact pricing is verified. If a current tier cannot be reduced to a stable verified price, a price check is safer than inventing a number.
Use your real numbers for the final decision
Before choosing, write down five things: your active subscriber count, expected monthly marketing sends, largest same-day campaign, number of users or editors, and whether you need provider branding removed.
Those inputs are more useful than a generic pros-and-cons list because they map directly to plan eligibility.

Methodology, freshness and source note
ChoiceSpec compares standard monthly list or renewal pricing. Introductory promotions and annual-prepayment discounts are not treated as ordinary month-to-month prices.
For MailerLite, current new-customer limits and prices are taken first from the canonical pricing page. Dated billing or plan-change Help is used to resolve transitions or legacy figures. Product and use-case landing pages are used only when they agree with those higher-priority sources.
That hierarchy matters because some MailerLite use-case pages still show older Free-plan figures. MailerLite’s dated Free-plan change notice confirms that the previous 500-subscriber, 12,000-email and one-seat limits were replaced by the current 250-subscriber, 2,500-email and two-seat limits.
Brevo’s current Free, Starter and Standard plan facts in this draft come from Brevo’s official pricing-plan Help documentation.
ChoiceSpec recommendations are based on requirements, not affiliate relationships. A free plan, a tie or no suitable covered option are all valid outcomes.
Paid tiers, plan packaging and feature gates can change quickly. Any exact paid price or final plan recommendation should be rechecked immediately before publication.
