Klaviyo vs MailerLite: Same 250 Free Contacts, an $838.80 Gap at 10,000

TL;DR: This is the pairing where the free plans are most symmetric — both stop at 250 accounts (MailerLite counts subscribers, Klaviyo counts active profiles) and the first paid steps are nearly identical ($19 a month for MailerLite's 251–1,000 band against $20 for Klaviyo's 251–500 rung). The bills separate with scale: $33 against $60 at 2,500 subscribers, $89 against $150 at 10,000 — $61 a month at the top, and $961.20 against $1,800 over a year ($838.80 apart) once MailerLite's 10% yearly rate is applied and Klaviyo's no-annual-rate year is priced as arithmetic. The growth steps point opposite ways: MailerLite's steepest is at the small end (subscriber 1,001 takes Comfort from $19 to $33, up 74%), while Klaviyo's is in the middle (the 10,500–13,500-profile corridor, $25 per 500 profiles, $300 more a year at the first step). Five buyer types should think twice before switching, starting with anyone whose list hovers near 10,500 profiles.

Free tiers: the same ceiling, different allowances

Both vendors lead with a free plan, and both free plans end at the same number — 250. MailerLite's free tier covers 250 subscribers sending up to 2,500 emails a month on two seats; Klaviyo's covers 250 active profiles sending up to 500 emails a month, with a $5 SMS credit and support for the first 60 days. Below the ceiling, the difference is not the account count but the sending allowance — five times more email on MailerLite's free plan — and the trimmings.

The first paid step is where the symmetry almost holds. MailerLite's first band above the free plan covers 251 to 1,000 subscribers at $19 a month ($17.10 on the yearly plan); Klaviyo's first rung covers 251 to 500 active profiles at $20 a month, twelve monthly payments because no annual rate exists. A 300-person list pays $205.20 a year on MailerLite's yearly rate against $240 on Klaviyo — $34.80 apart, the closest the two bills ever get. From there every verified size diverges:

Accounts	MailerLite Comfort, monthly	MailerLite, yearly plan	Klaviyo Email, monthly	Klaviyo, a year
500	$12	$10.80/mo — $129.60	$20	$240 (12 × $20)
2,500	$33	$29.70/mo — $356.40	$60	$720 (12 × $60)
10,000	$89	$80.10/mo — $961.20	$150	$1,800 (12 × $150)
10,001	Next published band: up to 15,000 at $129 (+$480/yr)	$116.10/mo at 15,000	Next rung: 10,500 at $175 (+$300/yr)	$2,100 at 10,500 profiles

USD. MailerLite figures are its published Comfort bands, read from its pricing page on September 21, 2026, with nightly re-checks through October 3, 2026 finding no changes; the yearly column is MailerLite's own published rate, about 10% under twelve monthly payments. Klaviyo figures are from the 49-rung ladder read from its own pricing engine on September 24, 2026 (banner and add-ons re-checked October 1, 2026); Klaviyo publishes no annual rate at any size, so its yearly column is twelve monthly payments — arithmetic, not a vendor quote.

The growth steps point opposite ways

Neither ladder rises smoothly, and each one punishes a different stage of growth.

MailerLite bites at the small end. Subscriber 1,001 moves Comfort from $19 to $33 a month — up 74%, $168 more a year, triggered by a single signup. Its second-large step mirrors Klaviyo's corridor at the same size: past 10,000, the next published band is up to 15,000 at $129, a 45% jump worth $480 more a year — though the band's width makes each of those extra subscribers inexpensive on margin. The full band anatomy, including the unit cost that falls to $8.63 per thousand subscribers at 8,000 and rises again to $8.90 at 10,000, is documented in our MailerLite pricing guide.
Klaviyo bites in the middle. At 10,000 active profiles the bill is $150; at 10,500 it is $175 — $300 more a year for the 501st profile past the line — and every 500 profiles up to 13,500 costs another $25, a 14–17% raise per step. That corridor holds the most expensive marginal profiles on any ladder we have read. The counterweight sits just below: Klaviyo's ladder has no rung between 6,500 and 10,000, so a 7,000-profile list bills at the 10,000 price, and the 20,000 rung at $375 covers 5,000 more profiles than the 15,000 rung at $350 for $25 — the cheapest stretch in the pairing's upper half. The full 49-rung read is in our Klaviyo pricing guide.
The same list can cross both steps in one year of growth. A list that ends the year at 10,500 accounts has paid MailerLite's 1,001 step (if it started small) and would face Klaviyo's corridor — the two vendors' worst steps sit at opposite ends, which is why the shape matters more than any single row.

The annual gap: a discount against an arithmetic

At 10,000 accounts the yearly bills are $961.20 on MailerLite (its published yearly rate, $80.10 a month) against $1,800 on Klaviyo (twelve monthly payments of $150, because Klaviyo publishes no annual rate at any size) — $838.80 apart. That is the largest annual-billing gap between any two vendors we price at a size both verify.

The two annual structures behave differently beyond the number. MailerLite's yearly plan takes about 10% off every band but locks the account for the term: a downgrade requested mid-term takes effect the following cycle, so the saving is also a commitment. Klaviyo's non-existent annual rate is the opposite trade — no commitment, no discount, and a first-month promo that barely registers: $19 off the first month, on the 500-profile plan only, with no published end date. A buyer comparing year-one cash outlay at 500 accounts sees $129.60 against $221 (Klaviyo's first month at $1 with the banner credit, then $20 a month); a buyer comparing year two sees $129.60 against $240.

What each bill actually measures

Both vendors bill the list rather than the sending, but the units differ in ways that reach the invoice. Klaviyo's billable unit is the active profile, and its send allowance is set at ten emails per profile at every rung — a 10,000-rung account buys 100,000 emails a month whether or not it sends them. MailerLite's unit is the subscriber count taken across the billing cycle: any address that was active at any point in the cycle keeps counting toward the band even after it is deleted, until the billing anniversary resets the number. A store pruning dead contacts before a Klaviyo renewal and a newsletter operator trimming a MailerLite list before an anniversary are doing the same chore with different clocks — and both clocks favor checking the count before the billing date, not after.

Who shouldn't switch

Lists hovering near 10,500 profiles. On Klaviyo, a list that oscillates around the corridor entrance pays for the oscillation — each dip back under 10,500 and return costs nothing retroactively only if the rung is re-billed monthly, and the corridor's $25-per-500 pricing makes 10,001–13,500 the most expensive marginal profiles we have verified. A store at 10,200 profiles should either grow past the corridor or trim below the line before the next cycle; drifting is the one move the corridor punishes.
Small lists on MailerLite eyeing Klaviyo's commerce stack. The first paid steps are near-identical, but at 2,500 subscribers the bills are $33 against $60 and at 10,000 they are $89 against $150. Moving to Klaviyo for the e-commerce features means accepting a bill that is 68–82% higher at every verified size from 2,500 upward — a trade that should be priced against real attributed revenue, which neither vendor's pricing page provides.
Buyers who need an annual invoice number. Klaviyo publishes no annual rate at any size, so any budget line for Klaviyo beyond month one is arithmetic, not a quote. If procurement requires a vendor-stated annual figure, MailerLite's yearly plan provides one at every band and Klaviyo cannot.
Lists under 250 accounts on either free plan. Both bill $0 here, so switching buys nothing in plan price; the only real differences below the ceiling are the sending allowance (2,500 emails a month on MailerLite against 500 on Klaviyo), seats, and Klaviyo's 60-day support window. The free-plan shapes across all six vendors we price are compared in our free-plan breakdown.
Buyers who clean the list after the billing date. MailerLite's cumulative counting rule keeps deleted addresses on the bill until the anniversary, and Klaviyo's profile count is set by its own plan terms — on both platforms, the savings from a cleanup lag the cleanup itself. Trim before the cycle closes, not after, whichever vendor you stay on.

How we keep these numbers honest

MailerLite's Comfort bands — $12 at 500 subscribers through $89 at 10,000 and $129 at 15,000, with the yearly rates at every band — were read from its own pricing page on September 21, 2026, and the nightly re-check through October 3, 2026 found no changes. Klaviyo's Email-plan ladder — $20 at 500 active profiles, $60 at 2,500, $150 at 10,000, $175 at 10,500 — was read rung by rung from Klaviyo's own pricing engine on September 24, 2026, with the banner and add-on lines re-checked on October 1, 2026; where Klaviyo publishes nothing (an annual rate, at any size), this site prints the gap instead of estimating one, the same rule applied in our Klaviyo vs Mailchimp comparison.

Frequently asked questions

Is Klaviyo or MailerLite cheaper at 10,000 subscribers?

MailerLite, by a wide margin on published prices. Its Comfort band at 10,000 subscribers bills $89 a month, or $80.10 a month on the yearly plan ($961.20 a year). Klaviyo's Email plan at 10,000 active profiles bills $150 a month, and no annual rate is published at any size, so the year is twelve monthly payments: $1,800. That is a $61 monthly gap and $838.80 over a year.

Do Klaviyo and MailerLite really both stop their free plans at 250?

Yes — both free ceilings are 250 accounts (MailerLite counts subscribers, Klaviyo counts active profiles), which makes this the pairing where the free plans are most symmetric. What differs under the ceiling is the sending allowance and the trimmings: MailerLite's free plan covers 2,500 emails a month on two seats, while Klaviyo's covers 500 emails a month with a $5 SMS credit and support for the first 60 days.

What does the first paid year cost just past the free plan?

The first paid steps are nearly identical. MailerLite's first band above the free plan covers 251 to 1,000 subscribers at $19 a month, or $17.10 on the yearly plan ($205.20 for the first year). Klaviyo's first rung covers 251 to 500 active profiles at $20 a month, $240 over twelve months because no annual rate exists. The gap at this size is $14.40 a year — the last time the two bills are close.

Does Klaviyo offer annual billing?

No annual rate is published at any list size, which makes Klaviyo the only vendor on this site with no annual option anywhere on its ladder. Any annual figure for Klaviyo is arithmetic — the monthly price times twelve, $1,800 at 10,000 active profiles — not a vendor quote. MailerLite publishes a yearly rate at every band, about 10% under twelve monthly payments.

Which vendor's ladder steps harder as the list grows?

They punish different sizes. MailerLite's steepest step is at the small end: subscriber 1,001 moves Comfort from $19 to $33 a month, up 74%, $168 more a year. Klaviyo's is in the middle: profile 10,501 starts a corridor where every 500 profiles cost $25 — the first step is $150 to $175, $300 more a year, and the corridor runs to 13,500 profiles, the most expensive marginal profiles on any ladder we have read.

Is Klaviyo worth the premium over MailerLite?

The $61-a-month difference at 10,000 subscribers is the sticker price of Klaviyo's e-commerce focus, and whether the revenue tools justify it depends on store data this site does not test. What the published prices do establish is the shape of the bills: Klaviyo costs more at every verified size from 500 profiles upward, never discounts for a year-long commitment, and steps hardest between 10,500 and 13,500 profiles — while MailerLite undercuts it at every band, locks its 10% yearly rate until the term ends, and steps hardest at 1,001 subscribers.
