ActiveCampaign vs MailerLite: simplicity or depth

MailerLite’s send button won’t fire; ActiveCampaign’s just waits for a human to look

MailerLite blocks a noncompliant send outright — the postal address and unsubscribe link can’t be removed, and a missing one triggers a hard error — while ActiveCampaign instead holds the same kind of campaign for manual review, refusing third-party links but publishing no numeric deadline for either policy. Scope compared, criterion by criterion. Checked 7 September 2026.

MailerLite vs ActiveCampaign: scope compared, criterion by criterion — checked September 7, 2026
MailerLite	ActiveCampaign
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.	Contacts, lists, campaigns, event-triggered automations, and deals arranged into pipelines with stages and tasks
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 marketing automation manager who builds triggered multichannel journeys, rather than the CRM admin who structures records and cross-team visibility
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.	Opens on plain-text emails are not measured, and the Campaign Overview report stays non-exportable according to the published help pages
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.	A dedicated IP at $750 each, open on every tier — but conditional on at least one hundred thousand engaged contacts. Volume is the barrier, not the plan
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 with image, text, button, video, timer, menu and free HTML blocks; over one hundred and twenty-five templates; conditional content on all four tiers
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.	Dynamic segments recomputed in real time, with and/or logic and groups. Official cap of twenty conditions per segment, five of them action-type and three uses of the contains operator
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.	Entry from Starter, but capped at five actions per automation. If/Else branches start at Plus; random splits and automation chaining require Professional
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.	Up to five variations on subject, sender and full content, with a per-variation list percentage and a winner picked automatically after two days by default
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.	Dual: a plan priced by contact count, plus a monthly send cap of ten to fifteen times that number. Past it, $0.005 per email, then a hard stop at three times the cap
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 on by default for list signup forms. The data processing agreement binds nothing until it has been executed from the account itself
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.	ActiveCampaign blocks a non-compliant send: the campaign is held for review if the address or unsub link is invalid, third-party links refused. The 10-day deadline is only in the glossary, not a platform rule. No state law named.
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.	Campaign reports export to CSV, but the Campaigns Performance report is limited to Plus, Professional and Enterprise: it does not exist on Starter
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.	The vendor states no share link exists for a custom report. Distribution is limited to three internal visibility levels, restricted to account users
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 v3 REST API is included on all four tiers at no extra cost, capped at five requests per second per account, returning a 429 beyond
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 a thousand apps advertised, but the CRM connectors that matter — Salesforce, Dynamics 365, Zendesk Sell — are reserved for the Enterprise tier
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.	Six help articles cover Google Ads, Google Contacts for import and sync, Google Sheets, and Google Analytics attached to campaigns
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.	A free migration exists, but a bounded one: lists, plus at most ten items per category across templates, automations and forms, and only for paying customers
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.	Live chat is English only, Monday to Friday, 3 a.m. to 11 p.m. US Central. The help center, for its part, exists in French
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.	Three named regions: United States, European Union, Asia-Pacific. But assignment follows the account's GEO IP and the vendor writes that it cannot be changed
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.	Two vendor pages contradict each other on refunds: one states there are none, the other grants one within thirty days. On an annual commitment, cancellation takes effect only at term
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 included on Starter and Plus, three on Professional, five on Enterprise. Starter caps additional purchases at one extra seat
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.	ActiveCampaign auto-assigns a region (EU/US/APAC) by GEO IP, no location or host named. Own SOC 2 Type 2 (annual report on request). Enterprise ships “HIPAA features”; FedRAMP, StateRAMP, GovCloud, BAA absent, tier undocumented.
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.	ActiveCampaign advertises 14 fully supported languages (Czech, Dutch, English...), English not distinguished. 5 more are contradicted: discontinued per help center, partial per site FAQ. No excluded screen documented.
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.	$15 per month for a thousand contacts on Starter, CRM and automations included. But Starter caps at twenty-five thousand contacts and five actions per automation
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.	Send volume, not contact count: ten times the contacts on Starter and Plus, then $0.005 per email. Sending is switched off at three times the cap
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.	ActiveCampaign charges US sales tax by billing address, as a separate line item (page dated 2025-03-17), no published state list. Exemption via documentation, approval at sole discretion. Nexus and per-state/local calc absent.
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).	Non-card billing opens at USD 2,500 annual commitment (wire/check); resold accounts excluded. FAQ states no threshold and ties PayPal to annual plans, help center sets the threshold without it. PO, net-30, ACH, W-9 absent.

Key takeaways

A hard error, not a warning, stops MailerLite’s send

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.

ActiveCampaign’s gate is a person, not a rule engine

ActiveCampaign holds a campaign for manual review instead, whenever the recipient address or the unsubscribe link fails validation, and refuses any third-party link outright. The ten-day deadline sometimes quoted for opt-outs lives only in its own glossary — never enforced as a platform rule — and no state law is named either. The two vendors reach a similar outcome, a stopped send, through two different mechanisms: an automated technical check on one side, a human review step on the other.

Both stay outside the United States, in different ways

MailerLite does not host in the United States at all: its data sits with Google Cloud, in Germany and the Netherlands, under its own ISO/IEC 27001:2022 certification, with the data centers separately certified too, and a stated Data Privacy Framework compliance; SOC 2, FedRAMP, StateRAMP, GovCloud, and a HIPAA BAA are all absent, with no tier published for any of them. ActiveCampaign instead auto-assigns a region — Europe, the United States, or Asia-Pacific — by GEO IP, naming no location or host, and holds its own SOC 2 Type 2 report; Enterprise ships “HIPAA features,” but the same four items stay undocumented.

Sixteen states plus DC against a line item with no list

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 and offering no calculation for the customer’s own sales. ActiveCampaign charges tax by billing address as a separate line item, on a page dated the seventeenth of March, twenty twenty-five, but never publishes which states, granting exemption only at its own sole discretion.

Self-service only, even past one hundred thousand subscribers

MailerLite accepts only card, PayPal, Przelewy24, or Shopify payment, no cash and no checks, priced in euros or US dollars by address — with no non-card tier published at any level, self-service only, even at its highest published plan, past one hundred thousand subscribers. ActiveCampaign opens non-card billing only above a twenty-five hundred dollar annual commitment, paid by wire or check, excluding resold accounts, though its own FAQ contradicts that threshold and ties PayPal only to annual plans instead.

How many US states does MailerLite collect sales tax in?

MailerLite collects and remits sales tax on its own fees in 16 states plus DC, at a combined state-plus-county rate based on zip code, and handles its own nexus determination. ActiveCampaign instead adds US sales tax as a separate line item by billing address, with no published state list. For a buyer comparing invoices, MailerLite states a wider footprint while ActiveCampaign discloses less about where its tax applies.

Do MailerLite or ActiveCampaign hold a FedRAMP certification?

Neither vendor publishes FedRAMP, StateRAMP, GovCloud or a HIPAA BAA tier. MailerLite holds only its own ISO/IEC 27001:2022 certification and states Data Privacy Framework compliance; ActiveCampaign holds SOC 2 Type 2 and ships Enterprise-only HIPAA features, but with no documented BAA tier. For a buyer needing a signed HIPAA BAA or a government-grade cloud, neither platform currently delivers one.

At what spend can ActiveCampaign be paid by wire instead of card?

Non-card billing on ActiveCampaign opens only at a 2,500 US dollar annual commitment, paid by wire or check, and resold accounts are excluded from it; no purchase order, net-30 or W-9 is published. MailerLite goes further the other way: it accepts only card, PayPal, Przelewy24 and Shopify payment, with no non-card tier at all, even for its largest Enterprise accounts of 100,000-plus subscribers.
