Klaviyo review

Klaviyo costs and plan spend

Klaviyo charges per message, and you buy the mobile plan upfront each month, as Klaviyo's pricing update confirms. The rate bundles carrier fees, so you will not see separate carrier line items on your bill.

Exact rates depend on your account and plan tier, and a free account lets you inspect them inside the app before you pay anything. Monthly spend resets, and unused amounts do not roll over.

Per Klaviyo's mobile messaging guide, cost is rate times recipients times segments, so one text can bill as several segments. Failed deliveries are charged, while skipped messages are not, and legacy credits apply only to accounts still using them.

Klaviyo sender choices

Your Australian sender choice drives cost, replies and media. A branded ID is the free default, but it is one-way, so it cannot receive replies or send MMS.

Per Klaviyo's sending-number guide, Australian long codes support replies, keyword and double opt-in workflows, and MMS, require a paid plan and carry no separate number charge.

Long-code verification takes an estimated one to three business days, and no sending happens until approval. Compare sender mechanics on our SMS marketing comparison page before you build flows around either option.

Australian sender registration

Klaviyo requires Australian branded sender registration through its own workflow, even for previously registered names. Per Klaviyo's branded sender guide, the published estimate is seven to ten business days, and resubmissions take the same time.

These are provider process estimates rather than guarantees, and they are not ACMA's own application duration. Klaviyo blocks unregistered branded IDs from sending to Australian recipients, and registration must finish before you collect SMS consent or send.

That product blocking is separate from ACMA's Unverified labelling rule, which the SMS Sender ID Register page explains. Registration asks for documents, identity verification by an appropriate representative, and domain or trademark evidence where the sender differs from the business name.

Consent when moving providers

Export valid opt-ins, separate opted-out contacts before import, and set the correct country for each number. Rows with invalid numbers are skipped. Turn off welcome flows triggered by consent events or the destination list, so unintended welcome sends cannot go out.

Klaviyo's contact import guide separates SMS marketing consent from SMS transactional consent, and those product consent classifications are not a legal exemption. Per ACMA's marketing guidance, a purchase alone does not establish inferred marketing consent.

Map subscribed, unsubscribed and never-subscribed states accurately, because a number or an email subscriber is not automatic SMS permission. A blank cell in a consent column defaults to never subscribed, and valid timestamps should be preserved when you hold them.

Test your sending workflow

Before your first campaign, send to one controlled Australian test recipient using the final expanded text. Count the message parts it produces, because the SMS character counter on our crafting page shows how Unicode and length change segment billing.

Confirm the selected sender matches the setup approved in your account, and check who owns inbound messages. After the import, verify the test contact was not enrolled in an unintended welcome sequence while flows were disabled.

Test the unsubscribe mechanism separately: click the unsubscribe link for a branded ID, or try the supported reply keyword for a long code. Failed deliveries are billed too, so a test message that does not arrive still costs money.

Klaviyo support and free plan

The free plan carries profile, email and mobile allowance limits, so it is not an unlimited Australian sending trial, and it does not include a free Australian long code. Klaviyo's public pricing page states the allowances.

On paid plans, email support runs round the clock, and live chat covers weekdays with weekend access varying by plan. Free accounts receive email support for their first sixty days, followed by self-service help.

Per Klaviyo's support guide, published Asia-Pacific business hours are nine in the morning to five in the afternoon Australian Eastern Time. Published access is not a response guarantee, and it does not confirm Australian-based staff.

Who should choose Klaviyo

Choose Klaviyo if you run email marketing, hold customer data you want to segment by behaviour, and value one platform for both channels. The SMS automation guide on our site shows how flows combine those data points into triggered sends.

Skip it if you want a standalone bulk SMS tool with a published Australian rate card, two-way messaging on a free plan, or MMS from a branded sender.

Before committing, check your per-message rate, your estimated monthly spend and whether your workflow needs replies and MMS, which points to a paid plan and a long code.
