ActiveCampaign vs Mailchimp: scope compared, criterion by criterion — checked September 7, 2026
ActiveCampaign	Mailchimp
What the tool answers
What it measures or produces
Contacts, lists, campaigns, event-triggered automations, and deals arranged into pipelines with stages and tasks	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 marketing automation manager who builds triggered multichannel journeys, rather than the CRM admin who structures records and cross-team visibility	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
Opens on plain-text emails are not measured, and the Campaign Overview report stays non-exportable according to the published help pages	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 at $750 each, open on every tier — but conditional on at least one hundred thousand engaged contacts. Volume is the barrier, not the plan	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
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	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 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	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
Entry from Starter, but capped at five actions per automation. If/Else branches start at Plus; random splits and automation chaining require Professional	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
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	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
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	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 on by default for list signup forms. The data processing agreement binds nothing until it has been executed from the account itself	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
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.	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
Campaign reports export to CSV, but the Campaigns Performance report is limited to Plus, Professional and Enterprise: it does not exist on Starter	A full export produces a single ZIP file, capped at one request per twenty-four hours. Campaign reports download separately, as CSV
Shareable reports
The vendor states no share link exists for a custom report. Distribution is limited to three internal visibility levels, restricted to account users	Sharing a report assumes the recipient holds an active Mailchimp account: the link alone grants nothing. Custom reports start at Standard
API access
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	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
Over a thousand apps advertised, but the CRM connectors that matter — Salesforce, Dynamics 365, Zendesk Sell — are reserved for the Enterprise tier	Over three hundred advertised. The three that decide: Shopify for the store, Salesforce for CRM, Google Analytics for measurement
Google tools it connects to
Six help articles cover Google Ads, Google Contacts for import and sync, Google Sheets, and Google Analytics attached to campaigns	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
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	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
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	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
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	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
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	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
One seat included on Starter and Plus, three on Professional, five on Enterprise. Starter caps additional purchases at one extra seat	One seat on Free, carrying Owner permissions only. Essentials opens three, Standard five, Premium an uncapped number
Data residency and regulated cloud
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.	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
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.	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
$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	$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
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	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
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.	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
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.	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

Twenty-one named jurisdictions against a number nobody wrote down

Mailchimp charges US sales tax in twenty-one jurisdictions — Colorado, New York, and Texas among them — based on the customer’s own address, with exemption limited to nonprofits and government bodies that provide documentation, and no per-state or local calculation offered for the customer’s own downstream sales. ActiveCampaign instead 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 are covered, and approves exemption only at its own sole discretion.

Mailchimp disputes its own P.O. box before either vendor blocks a send

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 process, and keeps the unsubscribe link valid for thirty days — yet two of its own pages accept a P.O. box as a compliant postal address while a third excludes it. ActiveCampaign instead holds a noncompliant campaign for manual review, refusing third-party links outright, though its own ten-day deadline lives only in its glossary, never enforced as a platform rule.

Fourteen languages on one side, a fixed six on the other

ActiveCampaign advertises fourteen fully supported languages without splitting US from UK English, yet five more are contradicted on its own site: discontinued according to the help center, only partial according to the FAQ. Mailchimp ships a plain six — English, Spanish, French, Portuguese, German, and Italian — though its video tutorials are captioned in only five of those, Italian left out, a separate matter from the fifty-plus languages its content-translation tool can render.

One region assigned by IP, one country and nothing else

ActiveCampaign 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 FedRAMP, StateRAMP, GovCloud, and a business associate agreement stay undocumented at any tier. Mailchimp hosts on its own US servers, with SOC 2 of an unspecified type plus ISO 27001, no FedRAMP, StateRAMP, GovCloud, or HIPAA BAA at all — and its own terms prohibit importing regulated sensitive data outright.

A $2,500 commitment on one side, a $350 ceiling on the other

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, stating none exists and tying PayPal only to annual plans. Mailchimp accepts card, PayPal, SEPA, and iDEAL alone; invoicing, a purchase order, net-30, ACH, and a W-9 are all absent, with what it calls an “invoice” amounting to a relabeled receipt, and card payment itself capped at Premium, three hundred fifty dollars a month.

Does Mailchimp block a non-compliant CAN-SPAM send?

No: Mailchimp does not block a non-compliant CAN-SPAM send, it auto-adds a default footer when unsubscribe or address tags are missing; opt-outs must be honored within 10 business days, and the unsubscribe link stays valid for 30 days. ActiveCampaign, by contrast, holds a non-compliant send for review if the address or unsubscribe link is invalid, and refuses third-party links outright. For a buyer wanting a hard stop on compliance issues rather than an automatic patch, ActiveCampaign blocks where Mailchimp only corrects.

In how many US jurisdictions does Mailchimp itself charge sales tax?

Mailchimp charges US sales tax in 21 named jurisdictions, including Colorado, New York and Texas, based on customer address, with exemption limited to nonprofits and government bodies holding documentation. ActiveCampaign charges US sales tax too, by billing address, as a separate line item, but publishes no state list at all, leaving nexus and per-state calculation unstated. For a buyer trying to anticipate tax exposure, Mailchimp names its jurisdictions where ActiveCampaign does not.

How many automation steps does Mailchimp allow on its Essentials tier?

Mailchimp caps automations at 4 steps on Essentials, rising to two hundred from Standard up; conditional branches, up to five conditions, and percentage splits also require Standard. ActiveCampaign allows automations from Starter onward, but caps them at 5 actions per automation, with If/Else branches starting at Plus and random splits requiring Professional. For a buyer building a complex automated journey, both vendors gate real branching logic behind a mid-tier plan.
