Fourteen languages, minus an unresolved five
ActiveCampaign advertises fourteen fully supported languages — Czech, Dutch, and English among them, English itself not split into any variant. Five more sit in outright contradiction: the help center calls them discontinued, the site FAQ calls them merely partial, and no page states which screens are actually excluded from either group. A buyer counting on one of those five has no single source to check against.
Klaviyo skips the contradiction, and still leaves whole features untranslated
Klaviyo ships eleven interface languages, keeping English as one entry while splitting Spanish into a Spain and a Mexico variant. Its translation gap is not a disagreement between two of its own pages but a stated exclusion: Flows AI, pre-built templates, and dynamic variables all stay outside the translated interface, regardless of which of the eleven languages an account runs in.
Neither vendor pins its region down the same way it claims to
ActiveCampaign auto-assigns a hosting region — EU, US, or APAC — by GEO IP, naming no specific location or host, and holds its own SOC 2 Type 2 report available on request; Enterprise ships something the vendor calls “HIPAA features”, but FedRAMP, StateRAMP, GovCloud, and any actual business associate agreement are all absent, at an undocumented tier. Klaviyo instead commits to one named location, AWS-East-1 in Northern Virginia, and a fuller certification list — SOC 2 Type II, ISO 27001, ISO 27017, PCI DSS — but reaches the identical absence on FedRAMP, StateRAMP, GovCloud, TX-RAMP, and any HIPAA BAA at any tier.
A dated line item against an undated rule
ActiveCampaign charges US sales tax by billing address, as a separate line item, on a page dated March seventeenth, twenty twenty-five, with no published state list; exemption runs through documentation approved at ActiveCampaign’s sole discretion. Klaviyo charges the same kind of tax at state and local level, with no state list and no date attached to the policy either, and an exemption that clears in three to five days once a certificate is filed. Neither names who carries nexus for the customer’s own downstream sales.
An annual commitment against a monthly one
ActiveCampaign opens non-card billing at a twenty-five-hundred-dollar annual commitment, paid by wire or check, with resold accounts excluded — and its own FAQ and help center disagree on the number, one stating no threshold and tying PayPal to annual plans, the other setting the threshold without mentioning PayPal at all. Klaviyo instead opens its non-card path at two thousand dollars of monthly plans, arranged through Customer Success, with ACH or wire and a W-9 supplied automatically; below either company’s line, card is the only option on both sides.
Only one of the two names consent on the same SMS page
ActiveCampaign’s SMS is a mandatory paid add-on, billed in credits, covering seven countries with local numbers and over a hundred eighty destinations reachable through US numbers — and its own page names an explicit requirement: opt-in consent plus 10DLC registration in the US. Klaviyo’s equivalent page, covering twenty-two named countries with push and WhatsApp included on a separate Mobile Messaging subscription, states a default quiet-hours window from nine p.m. to eight a.m. and nothing about consent or carrier registration at all. One page names the requirement; the other names only the hours.
A contradiction resolved is still a contradiction until then
ActiveCampaign’s disputed five languages and disputed billing threshold both share the same shape: two of its own pages stating two different things, with no third page settling either one. Klaviyo avoids that particular shape of problem, on languages and on threshold alike, but replaces it with stated exclusions and stated silences of its own — an untranslated Flows AI, an unlisted tax state, an SMS page quiet about consent.
