- Description: MailerLite, Brevo, Mailchimp, Kit, and Klaviyo solve different jobs. We ranked 5 email platforms by contact-metered vs email-volume vs creator-free vs ecommerce-profile, and what a $0–$20 plan actually keeps after unsubscribes, checkout ghosts, and the 10× send cap.

Email marketing software is not a [form builder](https://www.bestfirms.org/best-form-builder-software-2026). It is not an [AI copy stack](https://www.bestfirms.org/best-ai-marketing-tools-for-small-businesses). It is a list, a send, an unsubscribe, and a bill that grows when the list grows — or when the vendor decides a ghost still counts. The Google query treats MailerLite, Brevo, Mailchimp, Kit, and Klaviyo as rivals. They are not. One meters **Active** subscribers and ignores unsubscribes. One meters **emails sent**. One meters **subscribed, unsubscribed, and non-subscribed** contacts, so people who left still raise the tier. One gives you **10,000 subscribers free** and one automation. One bills **checkout profiles that never opted in**. Mix those jobs and you pay twice — once for the plan, and again when the tool is metering a contact the law will not let you mail.

**Key Takeaways**

- **There is no overall best.** Rank by job: cheap Active-only list, email-volume billing, incumbent with the unsubscribe trap, creator broadcasts, or ecommerce profiles.
- **The market splits in five.** MailerLite, Brevo, Mailchimp, Kit, Klaviyo.
- **The sticker is a billing unit, not a category.** [MailerLite Comfort starts at $12/mo; Power at $25](https://www.mailerlite.com/pricing?ref=bestfirms.org). [Brevo Starter is $9 monthly or $8.08 yearly](https://www.brevo.com/pricing/?ref=bestfirms.org) from 5,000 emails; Standard is **$18** / **$16.17**. [Mailchimp Essentials is $13 and Standard is $20](https://mailchimp.com/pricing/marketing/?ref=bestfirms.org) at 500 contacts. [Kit Newsletter is $0 up to 10,000](https://kit.com/pricing?ref=bestfirms.org); Creator is **$33/mo** or **$390/yr** at 1,000\. [Klaviyo Free is 250 profiles and 500 emails/mo](https://www.klaviyo.com/pricing?ref=bestfirms.org).
- **CAN-SPAM is why the footer exists.** The [FTC guide](https://www.ftc.gov/business-guidance/resources/can-spam-act-compliance-guide-business?ref=bestfirms.org) covers **every commercial message, including B2B**. Each violating email is subject to **up to $53,088**. You get **10 business days** to honor an opt-out. A valid physical postal address is required.
- **A signup form is not a list.** A [form](https://www.bestfirms.org/best-form-builder-software-2026) collects the address. This product stores consent, sends, and bills the row.

## What email marketing software is (and what it is not)

The product is a closed loop: capture → consent → send → unsubscribe → next send without a lawyer. That is not [first-party data strategy](https://www.bestfirms.org/first-party-data-strategy-building-an-owned-audience-before-you-need-one) (how you own the audience). Two jobs share the label and almost none of the checkout: a **newsletter / campaign sender** and an **ecommerce engine** (placed-order events, flows, revenue attribution). MailerLite, Brevo, Mailchimp, and Kit are built for the first, with different meters. Klaviyo is built for the second. Buy the first for a Shopify catalog and you rebuild the flows. Buy the second for a weekly founder letter and you pay for profiles you never mail.

## How we ranked

Five checks, not a composite score: **job**, **whether a price is published**, **what the meter actually is**, **what the floor keeps**, and **real annual cost**. Prices checked against official pages on 20 August 2026\. Annual billed rates first where published.

## Quick picks by job

**A published list under $15 with unsubscribes off the meter.** MailerLite Comfort from **$12 a month**. Free is **250 Active subscribers** and **2,500 emails**.

**Pay for emails sent, not contacts stored.** Brevo Starter at **$8.08 a month billed yearly** from **5,000 emails**. Automation sits on **Standard at $16.17**.

**The incumbent, if you already live there.** Mailchimp Standard at **$20 a month** for **500 contacts** and **6,000 sends**. Essentials at **$13** has **four flow steps** and no generative AI. Unsubscribed contacts still count.

**Broadcasts to 10,000 people at $0.** Kit Newsletter: unlimited landing pages and forms, **one** Visual Automation, **one** user. Creator is **$390 a year** at 1,000 subscribers.

**Shopify / WooCommerce revenue attribution.** Klaviyo Free at **250 profiles** and **500 emails**. A checkout email without an opt-in is still an active profile.

## Comparison: 5 platforms

## Cheap Active-only list: MailerLite

Right buy when the job is campaigns and a budget number, and you refuse to pay for people who left. Wrong buy as the Shopify revenue engine.

[Free is $0 for 250 Active subscribers](https://www.mailerlite.com/pricing?ref=bestfirms.org): **2,500 emails** a month, **2 seats**, **3 automations**, **3 forms**. [Comfort starts at $12 a month](https://www.mailerlite.com/pricing?ref=bestfirms.org) (tiers **500–200,000**; annual **10% off**): **3 seats**, **50 automations**, send cap **10× the tier ceiling** — 5,000 subscribers is **50,000 emails**. [Power starts at $25](https://www.mailerlite.com/pricing?ref=bestfirms.org): unlimited emails (fair use) and seats. New pricing shipped **16 June 2026**.

Trap: **Unsubscribed and bounced do not count. Deleted Actives still do, until the billing anniversary.** Delete on the 1st and bill on the 5th and the address still counts. Deleting and re-uploading to dodge the cap violates the terms. Power is the unlimited-send SKU, not a cheaper Comfort.

## Email-volume billing: Brevo

Right buy when the list is large, the send is rare, and receipts can share the invoice. Wrong buy if the product is a 12-step nurture and you stopped at Starter.

[Free is 300 emails a day](https://www.brevo.com/pricing/?ref=bestfirms.org). [Starter is $9 a month, or $8.08 billed yearly](https://www.brevo.com/pricing/?ref=bestfirms.org) from **5,000 emails**. Logo-off is **$10.80 extra**. [Standard is $18, or $16.17 yearly](https://www.brevo.com/pricing/?ref=bestfirms.org): **marketing automation**, A/B tests. [Professional is $499, or $449.08 yearly](https://www.brevo.com/pricing/?ref=bestfirms.org) from **150,000 emails**, **10 seats**.

Trap: **Starter is not the automation plan.** Journeys start on Standard. A 40,000-contact list that gets one campaign a month still fits 5,000 emails. The same list on Mailchimp is a contact-tier problem before the first send.

## Incumbent, unsubscribe meter: Mailchimp

Right buy when the team already knows the editor, Standard automations are the job, and you will **archive** the dead. Wrong buy if you think Essentials at $13 is “email marketing.”

[Free is 250 contacts and 500 emails a month](https://mailchimp.com/pricing/marketing/?ref=bestfirms.org) (or **250 a day**), **1 seat**, no AI; sending pauses at the cap. [Essentials is $13 at 500 contacts](https://mailchimp.com/pricing/marketing/?ref=bestfirms.org): **5,000 sends (10×)**, **4 flow steps**, no generative AI. [Standard is $20 at 500](https://mailchimp.com/pricing/marketing/?ref=bestfirms.org): **6,000 sends (12×)**, **5 seats**, up to **200 flows**. [Premium is $350 at 10,000 contacts](https://mailchimp.com/pricing/marketing/?ref=bestfirms.org): **150,000 sends (15×)**.

Trap: [**Subscribed, unsubscribed, and non-subscribed contacts all count**](https://mailchimp.com/help/about-your-contacts/?ref=bestfirms.org)**.** Archived, cleaned, and deleted do not. Essentials is testing and scheduling. Multi-step automation is Standard. The no-card trial caps you at **100 emails** until you add payment.

## Creator broadcasts: Kit

Right buy when the job is a newsletter or course and 10,000 people on one automation is enough. Wrong buy as the B2B lead-scoring CRM.

[Newsletter is $0](https://kit.com/pricing?ref=bestfirms.org) up to **10,000 subscribers**: unlimited broadcasts, landing pages, and forms, **1** Visual Automation, **1** user. [Creator is $33 a month, or $390 billed yearly](https://kit.com/pricing?ref=bestfirms.org) at **1,000 subscribers**: unlimited automations, A/B subjects, **2** users. [Pro is $66 a month, or $790 yearly](https://kit.com/pricing?ref=bestfirms.org) at 1,000: unlimited users. Digital-product fees are **3.5% + 30¢** on every plan.

Trap: **Free’s 10,000-subscriber cap is not the paid floor.** Creator’s published price is **1,000 subscribers**. Stay on Newsletter at 8,000 if one automation is the product. Leave when the product is a 12-email course. One user on Free is the agency deal-breaker.

## Ecommerce profiles: Klaviyo

Right buy when the catalog is on Shopify or WooCommerce and the email has to know the cart. Wrong buy as a $0 newsletter host past 250 profiles.

[Free is 250 active profiles, 500 emails a month, and $5 of mobile](https://www.klaviyo.com/pricing?ref=bestfirms.org). Paid email is a **profile + send** tier. [Klaviyo’s billing help](https://help.klaviyo.com/hc/en-us/articles/115000976672?ref=bestfirms.org) (25 March 2026) bills **active profiles**, typically **10×** sends. A help-center example is **$100 a month** at **5,000 profiles / 50,000 emails**. Customer Hub (**$20**) and Helpdesk (**$10**) are not the email SKU.

Trap: **An active profile is anyone you can still email, “regardless of consent status.”** Checkout without an opt-in still bills. Suppressed profiles drop off once processed — the opposite of Mailchimp — but allow **72 hours**, and be **24 hours** ahead of the cycle. Marketing Analytics is a separate **$100** from 13,500 profiles. Do not buy a CDP to get a newsletter.

## Worked annual cost at published floors

Assumptions: U.S. company, annual billing where published. MailerLite Comfort floor. Brevo yearly. Mailchimp Standard at the 500-contact sticker. Kit Newsletter until 10,000\. Klaviyo Free until 250; the 5,000-profile help-center example after that.

| Situation                           | MailerLite                  | Brevo                           | Mailchimp                      | Kit                              | Klaviyo                      |
| ----------------------------------- | --------------------------- | ------------------------------- | ------------------------------ | -------------------------------- | ---------------------------- |
| 250 people, light send              | $0 (Free, 2,500 emails)     | $0 (300/day)                    | $0 (Free, 500 emails)          | $0                               | $0 (500 emails)              |
| 500 contacts, paid automations      | $144 (Comfort $12 × 12)     | $194 (Standard $16.17 × 12)     | $240 (Standard $20 × 12)       | $0 if 1 automation               | Over Free                    |
| 5,000 store profiles                | Comfort 10× = 50,000 emails | Email slider, not a profile tax | Contact tier + 12×             | $0 on Newsletter if 1 automation | **$1,200** ($100/mo example) |
| 10,000 newsletter names, broadcasts | Comfort/Power tier          | Email volume                    | Premium **$4,200** ($350 × 12) | **$0** (Newsletter cap)          | Profile tier                 |

At 10,000 broadcast names and one automation, Kit Newsletter is **$0** and Mailchimp Premium’s 10,000-contact sticker is **$350 a month**. That is a meter gap, not a quality gap. At 5,000 store profiles, Klaviyo’s own example is **$1,200 a year** before SMS or Analytics.

## When it breaks

**The billing unit is not the job.** MailerLite meters **Active** (unsubscribes off; deleted Actives on until the anniversary). Mailchimp meters **subscribed + unsubscribed + non-subscribed**. Brevo meters **emails**. Kit meters **subscribers** with a 10,000 free cap. Klaviyo meters **profiles you can still email**. A [SaaS spend](https://www.bestfirms.org/saas-spend-management-how-to-cut-20-without-breaking-workflows) review that compares “$13 vs $12” without naming the unit is a fiction.

**An unsubscribe that still costs money.** Mailchimp keeps the row. Archive or the tier moves. MailerLite and Klaviyo (once suppression processes) do not charge it. CAN-SPAM still requires you to honor the opt-out. Deleting the person is not the same as stopping the bill.

**Starter without journeys.** Brevo Starter at $9 has no automation. Mailchimp Essentials has **four flow steps**. Kit Free has **one**. A welcome series needs MailerLite Comfort, Brevo Standard, Mailchimp Standard, or Kit Creator.

**A Shopify storefront is not a newsletter.** [Agentic storefronts](https://www.bestfirms.org/shopify-agentic-storefronts-are-on-by-default) already show the catalog. Klaviyo mails the cart. Kit will send a campaign.

**ActiveCampaign’s public page does not print a dollar until you pick a contact band.** Starter is **5 automation actions** and **1 user**. If the RFP needs a published rate, stay in the table above.

**CAN-SPAM is not a footer plugin.** No B2B exception, **10 business days** to honor opt-out, mechanism live **30 days** after the send, truthful From/subject, physical postal address, **$53,088** per violating email. Hiring a vendor does not contract the liability away.

## A 15-minute way to choose

1. Write the job: weekly newsletter, B2B nurture, or store flows tied to orders.
2. Newsletter, cheap, unsubscribes off the bill: MailerLite Comfort from $12\. Free only if 250 Active and 2,500 emails is the ceiling.
3. Fat list, thin send, receipts on the same invoice: Brevo Starter at $8.08 yearly. Standard at $16.17 the minute you need a journey.
4. Already in Mailchimp: Standard at $20 if you need automations. Archive unsubscribed and non-subscribed. Essentials at $13 is not that product.
5. Creator list under 10,000, one automation: Kit Newsletter at $0\. Creator at $390 a year when sequences are the product.
6. Shopify / WooCommerce catalog: Klaviyo. Free until 250 profiles. Budget the profile tier, not the $0 row.
7. Confirm the footer: physical address, working opt-out, 10-business-day honor window. Fail the meter, change lanes.

## Frequently Asked Questions

### What is the best email marketing software in 2026?

There is not one. MailerLite Comfort from $12 for an Active-only list. Brevo Starter at $8.08 yearly when you bill emails (Standard at $16.17 for automation). Mailchimp Standard at $20 when you are already there and will archive the dead. Kit Newsletter at $0 up to 10,000 with one automation. Klaviyo when the email has to know the cart.

### Does Mailchimp charge for unsubscribed contacts?

Yes. Official help: subscribed, unsubscribed, and non-subscribed contacts count toward the monthly contact limit. Archived, cleaned, and deleted do not. MailerLite counts only Active. Klaviyo drops suppressed profiles after processing.

### Is there a good free email marketing plan?

Kit Newsletter: **10,000 subscribers**, one automation, one user. MailerLite Free: **250 Active**, **2,500 emails**. Mailchimp Free: **250 contacts**, **500 emails**. Brevo Free: **300 emails a day**. Klaviyo Free: **250 profiles**, **500 emails**. A Gmail BCC is not email marketing software.

### How is ecommerce email different from a newsletter?

A newsletter is a send to a list. Ecommerce email is a flow fired by checkout events, with revenue on the campaign. Klaviyo is built for the second. Kit and MailerLite host the first.
