Mailchimp vs MailerLite: price and deliverability

MailerLite’s system refuses to send; Mailchimp’s just tapes a footer over the gap

MailerLite technically blocks a noncompliant send — the postal address and unsubscribe link can’t be removed, and a hard error stops the campaign — while Mailchimp lets the same send through by auto-adding a default footer when the required tags are missing, and its own pages even disagree on whether a P.O. box counts as that address, two accepting it and a third excluding it. Scope compared, criterion by criterion. Checked 7 September 2026.

MailerLite vs Mailchimp: scope compared, criterion by criterion — checked September 7, 2026
MailerLite	Mailchimp
What the tool answers
What it measures or produces
It produces email campaigns, automations, forms, landing pages and websites, then measures opens, clicks, unsubscribes, spam complaints, orders and revenue per campaign and per subscriber.	The contact, held in one or more audiences and targeted by email or SMS campaigns. Billing itself is computed on that stored contact count
The job it equips
The email marketing manager or independent creator who builds and mails their own list, designs the emails and tracks conversions without needing a developer.	The marketer who designs and sends their own campaigns inside a small business, with no production team and no integrator behind them
What it cannot tell you
It does not relay transactional email: MailerLite provides no SMTP infrastructure and routes that use case to MailerSend, a separate product with its own pricing.	A real open rate: the vendor states that Apple Mail Privacy Protection inflates opens and blocks any read on location, device or mail client
Send, deliver, measure
Deliverability
A dedicated IP requires fifty thousand weekly emails and one authenticated domain, with warm-up handled by the deliverability team; every new account must request approval before sending.	No dedicated IP in the marketing plans: it exists only on the transactional add-on, at $29.95 per month. DKIM and DMARC authentication is required above five thousand daily emails to Gmail
Editor and templates
Three editors coexist, drag-and-drop with over seventy content blocks, a simple editor and free-form HTML; over fifty pre-designed templates, restricted to the Comfort and Power plans.	Drag-and-drop up to four columns, vendor and saved templates. Custom HTML and conditional content are reserved for Standard and above
Segmentation
Dynamic segments recalculate continuously, with filters on custom fields, groups and automation activity; no cap on the number of conditions is published by the vendor.	Ten conditions maximum and no and/or logic on Free and Essentials. Unlimited conditions with combined logic start at Standard; segments recompute on every send
Automated journeys
Seven standard triggers plus e-commerce triggers; three active automations on free, fifty on Comfort, unlimited on Power, which alone allows three triggers per workflow.	Four steps maximum on Essentials, two hundred from Standard up. Conditional branches, up to five conditions, and percentage splits also require Standard
A/B testing
Subject line, content, sender name and send time are testable, up to five versions of one element; a slider sets the sample and the winner goes out automatically to the remainder.	One variable of four — subject, sender, content, send time — up to three variations, ten per cent minimum sample, automatic winner by open, click or revenue
Billing unit
Billing is per active subscriber in tiers, paired with a monthly sending cap; exceeding either subscribers or sends triggers an automatic tier increase charged pro-rata.	By contact tier, computed on the cycle's peak, with sending capped at ten, twelve or fifteen times that count on Essentials, Standard or Premium. Overage adds billed blocks
GDPR compliance
Double opt-in is on by default on forms, the DPA is folded into the Terms with no separate signature, portability and erasure tools exist; no numeric retention period is stated.	Double opt-in configurable per audience, consent-checkbox forms whose wording is archived in plain text, and a DPA folded into the Terms of Use, with no separate signature
CAN-SPAM and state-law compliance
MailerLite technically blocks non-compliant sending: the postal address and unsubscribe link can't be removed, an error blocks send if absent, one-click unsubscribe on by default. No numeric deadline or state law is published.	Mailchimp does not block a non-compliant CAN-SPAM send: it auto-adds a default footer if tags are missing. Opt-outs within 10 business days, link valid 30 days. No state law named. P.O. box accepted by 2 pages, excluded by a 3rd.
What comes out of it
Export formats
Subscribers export as CSV or CSV for Excel; a campaign report downloads as CSV and can be produced as PDF through the print function.	A full export produces a single ZIP file, capped at one request per twenty-four hours. Campaign reports download separately, as CSV
Shareable reports
Custom dashboards can be built and saved inside the account; no public share link for a report is described on the dedicated reports help page.	Sharing a report assumes the recipient holds an active Mailchimp account: the link alone grants nothing. Custom reports start at Standard
API access
A REST API is included, using Bearer tokens on connect.mailerlite.com/api, capped at 120 requests per minute, and 5 requests per minute on subscriber import endpoints.	The Marketing API is included at no announced extra cost, capped at ten simultaneous connections with a 429 beyond. Permissions follow the key owner's role
What it connects to
Native integrations
The directory advertises more than 130 connections; the three that matter are Shopify for e-commerce, WordPress for capture, and Zapier for everything else.	Over three hundred advertised. The three that decide: Shopify for the store, Salesforce for CRM, Google Analytics for measurement
Google tools it connects to
Google Analytics is enabled by automatically appending UTM tags to campaign links; Google Sheets, Google Forms and Google Docs appear in the integrations directory.	Two documented hooks: Google Analytics 4, tracking emails and hosted pages, and Google Lead Ads, feeding ad form submissions into an audience
Bringing your existing data across
Migration runs through a CSV export at the competitor then an import with field mapping; forms, templates and automations have to be rebuilt by hand.	The vendor's own Klaviyo migration guide is entirely manual: CSV export, segments and automations rebuilt by hand, HTML copied over, SMS contacts handled separately
Getting started, and the fine print
Support
Email support is 24/7 from the Comfort plan, 24/7 live chat is reserved for Power, priority support sits on Enterprise; free accounts get fourteen days then fall back to the community.	Six languages including French, over chat and email around the clock from the first paid tier. Phone is Premium only, and in English only
Where the data is hosted
Hosting runs on Google Cloud Platform in data centers located in Germany and the Netherlands; the DPA nonetheless permits worldwide processing framed by Standard Contractual Clauses.	The United States, named by the vendor, and nothing else: no European region is offered, transfers resting on Standard Contractual Clauses and the Data Privacy Framework
What happens if you leave
Cancelling downgrades the account to the free plan at the end of the cycle with data kept; deleting the account opens a twenty-five day grace period first.	No refunds outside a malfunction. Deleting the account erases audiences, archives and reports, with the vendor advising an export first; pausing keeps everything
Minimum seats billed
No minimum seat purchase applies: seats come bundled per plan, two on free, three on Comfort, unlimited on Power and Enterprise.	One seat on Free, carrying Owner permissions only. Essentials opens three, Standard five, Premium an uncapped number
Data residency and regulated cloud
MailerLite does not host in the United States: its data sits with Google Cloud, in Germany and the Netherlands. The vendor holds its own ISO/IEC 27001:2022 certification (its data centers are separately certified too) and states Data Privacy Framework compliance; SOC 2, FedRAMP, StateRAMP, GovCloud, and HIPAA/BAA are absent, with no tier published for any of them.	Mailchimp hosts on its own servers in the US (no region, no third-party host). Own certs: SOC 2 (type unspecified), ISO 27001. FedRAMP, StateRAMP, GovCloud, HIPAA BAA absent; importing regulated sensitive data is prohibited.
Interface languages shipped
MailerLite ships three interface languages: English by default, Spanish, and Polish, without distinguishing US from UK English. Spanish is switched self-service, Polish is enabled by contacting support.	Mailchimp ships the interface in 6 languages (English, Spanish, French, Portuguese, German, Italian). Video tutorials are captioned in 5 languages, Italian excluded. Distinct from sent-content translation tools (50+ languages).
What it costs
The entry price and what it includes
The Comfort plan starts at 12 US dollars per month billed monthly, with three seats, fifty active automations, pre-designed templates, A/B testing and round-the-clock email support.	$13 per month for five hundred contacts on Essentials, with sending capped at ten times the contact count. The vendor presents that figure as a starting price on one page and a twelve-month promotion on another
What pushes the bill up
Crossing the active subscriber tier triggers an automatic tier increase charged to the card, pro-rated against the time remaining in the billing cycle.	Billing runs on the peak contact count of the cycle, not the average. On overage nothing is cut off: contact blocks are added automatically, at a price visible only once logged in
Sales tax and nexus
MailerLite collects and remits sales tax on its own fees, in 16 states plus DC, at a combined state-plus-county rate by zip code. MailerLite bears its own nexus determination; no calculation is offered for customer sales.	Mailchimp itself charges US sales tax in 21 jurisdictions (Colorado, New York, Texas...), by customer address. Exemption limited to nonprofits/government bodies with documents. No per-state/local calc for the customer's own sales.
Procurement and invoicing
MailerLite accepts only card, PayPal, Przelewy24, and Shopify payment (Shopify accounts) — no cash or checks — in EUR or USD by address. No non-card tier published: self-service only, even for Enterprise (100,000+ subscribers).	Mailchimp accepts only card, PayPal, SEPA, iDEAL (§11); invoicing, PO, net-30, ACH, W-9 absent — an “invoice” is a relabeled receipt. Card only through Premium ($350/month); beyond 200,000 contacts, custom plan, no stated tier.

Key takeaways

One editor won’t let a bad send leave the building

MailerLite technically blocks a noncompliant send: the postal address and the unsubscribe link can’t be removed from a campaign, a missing one triggers an error that stops the send outright, and one-click unsubscribe stays on by default. No numeric deadline and no state law are published anywhere near the policy.

The other patches the send, then argues with itself about the address

Mailchimp does not block a noncompliant CAN-SPAM send: it auto-adds a default footer whenever the required tags are missing, gives ten business days for opt-outs to clear, and keeps the unsubscribe link valid for thirty days, naming no state law at all. Two of its own pages, though, accept a P.O. box as a compliant postal address, while a third page excludes it — a contradiction Mailchimp has not resolved.

Neither vendor hosts where the buyer might expect

MailerLite runs on Google Cloud, in Germany and the Netherlands, under its own ISO/IEC 27001:2022 certification, with a stated Data Privacy Framework compliance; SOC 2, FedRAMP, StateRAMP, GovCloud, and a HIPAA BAA are all absent. Mailchimp, conversely, hosts on its own US servers, with SOC 2 of an unspecified type plus ISO 27001, the same four regulated-cloud items missing — and its own terms prohibit importing regulated sensitive data outright, whatever the plan.

Three languages, self-service or not, against a fixed six

MailerLite ships three interface languages: English by default, Spanish switched self-service, and Polish enabled only by contacting support, with no US or UK English distinguished. Mailchimp ships six — English, Spanish, French, Portuguese, German, Italian — though its video tutorials are captioned in only five, Italian left out, apart from the fifty-plus languages its own content-translation tool can render.

Sixteen states plus DC against twenty-one jurisdictions

MailerLite collects and remits sales tax on its own fees in sixteen states plus the District of Columbia, at a combined state-and-county rate calculated by zip code, bearing its own nexus determination. Mailchimp instead charges tax in twenty-one jurisdictions, by the customer’s own address, exemption limited to nonprofits and government bodies with documentation. Neither vendor calculates the customer’s own downstream sales tax.

Does Mailchimp allow uploading regulated sensitive data?

No: Mailchimp explicitly prohibits importing regulated sensitive data, and while it hosts on its own US servers with SOC 2 (type unspecified) and ISO 27001 certifications, it publishes no FedRAMP, StateRAMP, GovCloud or HIPAA BAA tier. MailerLite does not host in the US at all, sitting with Google Cloud in Germany and the Netherlands, with only its own ISO/IEC 27001:2022 certification. For a buyer with HIPAA-covered data, neither vendor offers a documented path.

In how many jurisdictions does Mailchimp charge sales tax?

Mailchimp itself charges US sales tax in 21 jurisdictions, including Colorado, New York and Texas, based on customer address; exemption is limited to nonprofits and government bodies with documentation, and no per-state or local calculation is offered for the customer’s own sales. MailerLite instead covers 16 states plus DC at a combined state-plus-county rate by zip code. For a buyer outside those lists, neither page gives further tax guidance.

Up to what plan can Mailchimp only be paid by card?

Mailchimp accepts only card, PayPal, SEPA or iDEAL, with card as the sole option through the 350 US dollar per month Premium plan; beyond 200,000 contacts a custom plan applies, with no stated payment tier. No invoicing, purchase order, net-30, ACH or W-9 is documented — what the vendor calls an invoice is only a relabeled receipt. MailerLite is just as restrictive: card, PayPal, Przelewy24 and Shopify only.
