Email Billing Models: Does Sending More Often Actually Cost More?

By Fujino Kodai (operator) · Prices checked: 2026-11-15 · Research-based comparison — see "How we compared" below.

How we compared: This comparison is based on the vendors' official pricing pages and help documentation, checked on 2026-11-15. We have not run paid accounts of any of these tools for this article, so nothing below is a hands-on finding. Where a number could not be confirmed on an official page, we say so instead of guessing.

Last updated: 2026-11-15.

The short answer

No — not at a normal frequency. On the confirmed plans, sending once a month and sending eight times a month cost exactly the same, because Kit and beehiiv place no limit on sends and MailerLite Comfort and Mailchimp Essentials both allow up to 10 sends per subscriber per month before anything changes.

• Choose MailerLite Comfort if you want the lowest confirmed paid price and you send no more than about 10 emails per subscriber per month: $19/month at 1,000 subscribers and $89/month at 10,000 subscribers, unchanged between 1 and 8 sends per month in the scenarios below.
• Choose Kit or beehiiv if you send more than 10 times per subscriber per month, or you do not want to count sends at all: both place no sending limit on any plan, so frequency alone does not raise the bill.
• Choose Kit if the free runway matters most before you pay: its free plan holds up to 10,000 subscribers, the widest free limit here — the reverse of the paid ranking, where MailerLite is cheapest.
• Choose Mailchimp only after checking the price for your exact contact count: its billing model is confirmed (stored contacts, sends capped at 10× on Essentials), but its 1,000-contact and 10,000-contact Essentials and Standard prices are not confirmed in this article, so it is not ranked on price below.
• Choose none of them yet if you are still on a free plan and under its subscriber limit: frequency is not a reason to upgrade until you pass about 10 sends per subscriber per month on a capped plan, or outgrow the free subscriber limit itself.

Who each one is for

MailerLite fits you if…

• You send a weekly newsletter plus an occasional launch email — about 4 to 8 emails per subscriber per month — and you want that frequency to cost nothing extra: on Comfort, a 10,000-subscriber list costs $89/month whether you send once a month (10,000 emails) or eight times a month (80,000 emails), because the cap is 100,000 emails/month at that tier.
• You want the lowest confirmed paid bill at a small or mid-size list: Comfort is $19/month at 1,000 subscribers and $89/month at 10,000 subscribers, billed monthly.

MailerLite is probably not for you if…

• You regularly send more than 10 emails per subscriber per month — for example, a daily email to a 10,000-subscriber list: Comfort's 100,000-email/month cap at that tier is no longer enough, and the confirmed unlimited-sending step is Power at $129/month at 10,000 subscribers. If unlimited sending with no cap to track is the deciding point, compare Kit and beehiiv below first at your own list size — at 10,000 subscribers beehiiv Lite ($139/month) is in fact higher than MailerLite Power ($129/month), and Kit’s price at that size is not confirmed.
• You want a long free runway before paying: the free plan stops at 250 subscribers and 2,500 emails/month, and sending locks above 250 active subscribers. If growing free comes first, start with Kit instead.

Kit fits you if…

• You do not want to count sends at all: Kit's official help states that your bill is based on your active subscribers, not on emails sent, and its pricing FAQ states there are no sending limits on any plan.
• You are growing an audience before you pay: the free plan holds up to 10,000 subscribers, with no sending limit stated on the pricing page (see “Not confirmed” #7) — 40 times the subscriber limit of the MailerLite and Mailchimp free plans.

Kit is probably not for you if…

• The monthly bill itself decides: Creator is $39/month for up to 1,000 subscribers, against MailerLite Comfort at $19/month at the same size, and automations and sequences are paid-plan features on Kit. If you send within the 10× cap anyway, MailerLite gives you the same frequency headroom at a lower confirmed price.
• You need a confirmed price at 10,000 subscribers before you commit: Kit's Creator price at that tier is not confirmed in this article because the official pricing page shows it through an interactive selector, so do not budget from the $39/month figure at that size.

Mailchimp fits you if…

• Your sending fits the same pattern as MailerLite Comfort and you already run a Mailchimp account: Essentials allows sends up to 10× your contact limit per month, Standard up to 12×, and Premium up to 15×, so a weekly or twice-weekly routine sits inside the cap on any of them.
• You understand that its counting basis is different before you compare prices: Mailchimp counts contacts stored in your account, including unsubscribed contacts, while Kit and MailerLite count active subscribers only.

Mailchimp is probably not for you if…

• You need a confirmed like-for-like price at 1,000 or 10,000 contacts from this article: those Essentials and Standard tier prices are not confirmed here, and neither is the overage rate Mailchimp charges when a paid plan passes its contact or send limit. Do not choose it on price until you have checked the price for your exact contact count on Mailchimp's official page on the day you buy.
• You rarely clean your list: because unsubscribed contacts still count toward the stored total, a list you never archive can cost more here than the same active audience costs on an active-subscriber model.

beehiiv fits you if…

• You send frequently — or irregularly, with launch weeks far above your normal week — and you want no cap to plan around: beehiiv places no limit on sends on any plan, and its official pricing FAQ states you are never penalized for sending more often.
• You want confirmed prices at both a small and a larger list: Lite is $59/month for up to 1,000 subscribers and $139/month for up to 10,000 subscribers, billed monthly, with no change between sending once and sending eight times a month.

beehiiv is probably not for you if…

• The monthly bill decides and your frequency is ordinary: at both confirmed sizes, Lite costs more than MailerLite Comfort — $59/month against $19/month at 1,000 subscribers, and $139/month against $89/month at 10,000 — while a frequency of 8 or fewer sends per subscriber per month does not use the headroom you are paying for. If low running cost matters more, start with MailerLite instead.

How we compare

We compare the billing models in the order the question is actually asked: first, what the bill is based on — subscribers, stored contacts, sends, or a mix; second, what the same list costs at the same sending frequency, worked through in fixed scenarios; third, where the ranking actually flips, if it flips at all. A model name alone decides nothing — only the cap, the tier price, and what happens when you pass them change what you pay.

Pricing, compared on the same basis

How this table is ordered and dated: Rows are ordered by confirmed paid price at the 1,000-subscriber scenario, not by affiliate terms. Prices and limits below were checked on official vendor pages on 2026-11-15.

Prices in USD, before tax, monthly billing. Read the basis first — the tools do not all count the same thing. Kit counts unique, active subscribers and places no limit on sends. MailerLite counts active subscribers and also caps monthly sends. Mailchimp counts contacts stored in your account — including unsubscribed contacts — and also caps monthly sends. beehiiv counts unique subscriber addresses in a publication bucket and places no limit on sends. A “1,000-person list” is therefore not billed identically by all four. One reading note: where this article says a capped plan allows “up to 10 sends per subscriber per month”, that figure is at a full tier — the cap itself is 10× the subscriber-tier ceiling, so a list below its tier ceiling has more headroom per actual subscriber.

The same list, at three frequencies

The table below is the test behind the short answer. Scenarios B and C hold the list size (10,000 subscribers) and the plan fixed and change only how often you send — that pair is the frequency test. Scenario A is a separate case: the same weekly frequency (4 sends/month) at the smaller 1,000-subscriber size. Each price is for the cheapest confirmed paid plan that fits that use, billed monthly.

What the scenarios show: in the B-to-C pair — the only pair that changes frequency alone — raising frequency from 1 to 8 sends per subscriber per month changed the confirmed monthly price by $0 on every tool where a price could be confirmed. The paid ranking also did not flip with list size: at both 1,000 and 10,000 subscribers, the confirmed order is MailerLite Comfort first, then beehiiv Lite. Kit sits between them at 1,000 subscribers ($39/month) and is not ranked at 10,000 because its price there is not confirmed. Mailchimp is not ranked at either size for the same reason.

Where the ranking actually flips

1. Free versus paid — this ranking does flip, completely. Paid, cheapest first (confirmed, at 1,000 subscribers): MailerLite Comfort $19/month, then Kit Creator $39/month, then beehiiv Lite $59/month. Free, widest first: Kit up to 10,000 subscribers, then beehiiv up to 2,500, then MailerLite and Mailchimp at 250 each. The tool that is cheapest once you pay is near the bottom on how far you get before you pay, and the tool with the widest free plan is not the cheapest paid one. Which ranking matters depends on whether your next step is growing free or paying for automations and selling features.
2. Above about 10 sends per subscriber per month — the capped plans step up. At a 10,000-subscriber list sending 12 times a month (120,000 emails), MailerLite Comfort's 100,000-email cap is passed and the confirmed unlimited step is Power at $129/month — up from $89/month. That narrows the gap to beehiiv Lite ($139/month) from $50 to $10, but on the figures confirmed here it does not pass it. Kit and beehiiv, with no send limit, do not change price at that frequency in structure — though Kit's price at this list size is not confirmed, so no full ranking is claimed at that point. On Mailchimp Essentials, 120,000 emails at 10,000 contacts would pass the 10× cap and move into overage billing; the overage rate is not confirmed, and Standard's 12× cap (120,000 emails) would sit exactly at the limit.
3. List size alone does not flip it (in the confirmed range). The confirmed paid order at 1,000 subscribers and at 10,000 subscribers points the same way. Size changes how much you pay, and how soon a free plan runs out — it does not, on these figures, change which confirmed paid plan is cheaper.

A note on genuinely per-send pricing

None of the four tools above offers a purely per-send monthly plan, so there is no per-send price to rank them by. The only per-send option inside this set is Mailchimp's Pay As You Go credit model, and its credit price is not confirmed on the official pages checked for this article, so it is not used in any comparison here. Per-send services — for example Amazon SES — sit outside these four tools, and no per-send price is confirmed in this article, so none is ranked here. As a matter of arithmetic, the two models pull in opposite directions: a large list that sends rarely pays for contacts it rarely mails on a per-contact model, while very high sending volume accumulates charges on a per-send model. Neither direction is tested with confirmed prices in this article.

Compared by use case

Watch out for

1. There is no pure per-send plan to switch to inside this set. All four tools price mainly by list size, with sends as a cap at most. If an article or a discussion promises that a per-send model inside one of these four will reverse your ranking, check which plan it actually names — in this set, only Mailchimp Pay As You Go is send-based, and its credit price is not confirmed here.
2. “Unlimited sending” does not mean a fixed bill. Kit and beehiiv place no limit on sends, but both price by subscriber tier or bucket, so growing the list still raises the price. Kit's rise is automatic when you pass a tier; how beehiiv applies a bucket change is not confirmed in this article.
3. “Capped” does not mean “expensive at normal frequency.” A 10× cap sounds tight until you convert it: it is 10 emails to every subscriber, every month. A weekly newsletter uses 4. Most solo senders will hit a subscriber tier — or a free-plan subscriber limit — long before they hit a send cap.
4. What happens past the cap differs, and one rate is missing. MailerLite's official FAQ describes upgrading to Power or waiting for the next cycle when the Comfort send cap is reached — no Comfort send-overage rate is stated, so none is quoted here. Mailchimp bills overages on paid plans rather than pausing, but the overage rate is not confirmed. Do not budget for either excess from a third-party figure.
5. The counting basis can matter more than the model name. Mailchimp counts stored contacts including unsubscribed contacts; Kit counts unique, active subscribers; MailerLite counts active subscribers, counted cumulatively within the billing cycle, so deleting an address mid-cycle does not lower that cycle's count. The same audience can produce three different counted totals.
6. Free plans fail on subscribers before they fail on sends — except Mailchimp's. Kit’s pricing page states no sending limit for the free plan (its help wording differs — see “Not confirmed” #7), and MailerLite free allows 2,500 emails/month to at most 250 subscribers, which is the same 10-per-subscriber pattern. Mailchimp free is tighter on volume: 500 sends/month (250/day) to up to 250 contacts is only 2 sends per contact per month, so a weekly free newsletter does not fit it.
7. Prices and plan names in this category have already changed, and will again. MailerLite renamed its paid plans on 2026-06-16 — “Growing Business” became Comfort and “Advanced” became Power — Kit raised prices in 2025, and beehiiv renamed its plans in October 2026 (Launch became Free, Scale became Lite, Max became Pro). Kit is also the tool formerly called ConvertKit. Re-check every price in this article on the vendor's official page on the day you buy.
8. This is a documentation comparison, not a test. We did not measure deliverability, editor usability, or support quality on any of these tools. Use a free plan with your own list and your own sending routine before paying annually.

FAQ

Does sending more emails cost more on Kit, MailerLite, Mailchimp, or beehiiv?

Not at a normal frequency, on the confirmed plans. Kit and beehiiv place no limit on sends on any plan, and MailerLite Comfort and Mailchimp Essentials allow up to 10 sends per subscriber (or contact) per month. In the worked scenarios for this article, a 10,000-subscriber list cost the same at 1 send per month as at 8 sends per month on every tool where a price was confirmed.

At what frequency does sending start to cost more?

At about 10 sends per subscriber per month on the capped plans. That is where MailerLite Comfort's cap (10× the subscriber tier) and Mailchimp Essentials' cap (10× contacts) are reached. Above it, MailerLite's confirmed unlimited step at 10,000 subscribers is Power at $129/month (up from Comfort at $89/month), and Mailchimp Essentials moves into overage billing at a rate that is not confirmed in this article. Kit and beehiiv have no equivalent threshold because they have no send limit.

Is there a per-send pricing plan among these four tools?

No monthly per-send plan was confirmed among them. All four price mainly by subscribers or contacts, with sends as a cap at most. The only send-based option inside the set is Mailchimp Pay As You Go, a credit model whose credit price is not confirmed on the official pages checked here, so this article does not compare it on price.

Which tool is cheapest if I send a weekly newsletter?

MailerLite, on confirmed paid prices at the sizes tested. A weekly routine is about 4 sends per subscriber per month — inside every cap here — so frequency does not change the ranking, and Comfort is $19/month at 1,000 subscribers and $89/month at 10,000 subscribers, below Kit Creator ($39/month at up to 1,000) and beehiiv Lite ($59/month at up to 1,000; $139/month at up to 10,000). Mailchimp is not ranked because its prices at those sizes are not confirmed in this article.

Which free plan lasts longest if I am not paying yet?

Kit's, by subscriber count. Its free plan holds up to 10,000 subscribers, with no sending limit stated on the pricing page (see “Not confirmed” #7), against beehiiv free up to 2,500 subscribers, and MailerLite and Mailchimp free at 250 subscribers or contacts each. That is the reverse of the paid ranking, where MailerLite is the cheapest confirmed option — so the best free start and the cheapest paid start are different tools in this set.

Why is my Mailchimp count higher than my actual audience?

Because Mailchimp prices by contacts stored in your account, and that total includes unsubscribed contacts as well as subscribed ones (archived, cleaned, and deleted contacts are excluded). Kit counts unique, active subscribers and MailerLite counts active subscribers, so the same audience can count smaller there. Archiving contacts you no longer mail is the lever Mailchimp's own model gives you.

Should I switch to a per-send service like Amazon SES instead?

That comparison is outside the four tools priced in this article, and no per-send price is confirmed here, so this article does not rank it. As a matter of arithmetic, the trade-off runs in both directions: a large list that sends rarely can look expensive on a per-contact model, while very high volume can look expensive on a per-send model. Work it out at your own list size and your own sends per month — and count the deliverability, forms, and automation work a full email platform includes — before treating the sending charge alone as the whole cost.

Where to start

Repeating the verdict: frequency is effectively included free up to about 10 emails per subscriber per month, so choose on the paid price, the free runway, and whether you want a send cap at all — in that order for most solo senders.

• Start with MailerLite if you send up to about 10 times per subscriber per month and want the lowest confirmed paid price — begin free to test your routine, and expect Comfort at $19/month for 1,000 subscribers ($89/month at 10,000) when you outgrow the free plan. → Try MailerLite: Official site link — coming after partner registration
• Start with Kit if you want no send cap and the longest free runway — begin free up to 10,000 subscribers, and expect Creator at $39/month for up to 1,000 subscribers when you need paid features. The Creator price at 10,000 subscribers is not confirmed in this article, so check the price for your actual list size before you rely on a figure at that size. → Try Kit: Official site link — coming after partner registration
• Start with beehiiv if you want no send cap and confirmed prices at a larger list — begin free up to 2,500 subscribers, and expect Lite at $59/month billed monthly for up to 1,000 subscribers ($139/month at up to 10,000) when you need a paid plan. → Try beehiiv: Official site link — coming after partner registration
• Start with Mailchimp if you have checked the price for your exact contact count on Mailchimp's official page and the stored-contact basis fits how you run your lists — begin from Essentials at $13/month for 500 contacts, and confirm the tier price and the overage terms for your size before you commit, because neither is confirmed in this article. → Try Mailchimp: Official site link — coming after partner registration

Not confirmed in this article

1. Kit Creator and Pro prices at 5,000 and 10,000 subscribers — the official pricing page shows these tiers through an interactive selector, so no fixed figure could be read from official text. (Creator at the 3,000-subscriber tier, $59/month, was confirmed from a worked example in Kit's official billing help.) Kit's annual prices for the higher tiers are likewise not confirmed, and no annual figure is used in the scenarios.
2. Mailchimp Essentials and Standard prices at 1,000 contacts and at 10,000 contacts — shown through an interactive selector on the official pages checked. Confirmed Mailchimp figures used here are only the 500-contact starting prices (Essentials $13/month, Standard $20/month) and Premium from $350/month at a base tier of 10,000 contacts. Promotional pricing (for example, a first-year discount shown on the pricing page) was not used in any calculation.
3. Mailchimp's overage rate and formula — the official help confirms that overages are billed on paid plans past the contact or send limit, but no per-unit rate was confirmed on the pages checked.
4. Mailchimp Pay As You Go credit prices — the only send-based model inside this set of four tools. No credit price was confirmed on the pages checked, so Pay As You Go is not compared on price anywhere in this article.
5. MailerLite Comfort's overage rate for passing the monthly send cap — the official FAQ describes upgrading to Power or waiting for the next cycle, and states no per-email overage rate.
6. How beehiiv handles passing a subscriber bucket — automatic upgrade, overage charge, or neither — no statement was found on the official pricing page or its machine-readable version checked here.
7. Whether Kit's free plan has a sending limit — Kit's pricing FAQ states there are no sending limits on any plan, while a Kit help passage about cancelling refers to the free plan as having a lower sending limit. Because the official sources do not agree in wording, this article follows the pricing FAQ for paid-plan comparisons and does not claim a specific free-plan send cap beyond “no limit stated on the pricing page.”
