  The 2026-05-04 bulk-sweep version (method:generated) which recorded three tiers —
  Free / Email ($20/mo from 251 profiles) / Email+SMS ($35/mo, 1,250 SMS credits). Those
  figures could not be re-verified on the live pricing page on 2026-08-13 and the Free
  tier's own allowances have changed (mobile messaging is now expressed as a $5/month
  budget, not 150 SMS credits, and a Composer credit allowance has been added). The
  unverifiable paid-tier numbers are removed rather than carried forward.

description: >-
  Klaviyo prices on active profiles, with separate metered allowances for email sends and
  mobile messages. There is a permanent free tier. Paid pricing is quoted through an
  interactive calculator on the pricing page rather than published as a static tier
  table, so exact paid-tier prices are not machine-readable.

plan_count_note: >-
  ONE plan is fully published with concrete figures — the Free tier, transcribed below
  verbatim from the pricing page. Paid tiers exist but are priced by a calculator that
  computes a total from the profile count and product mix selected; no static per-tier
  price table is rendered on the page, and no machine-readable pricing endpoint was
  found. Recording plan_count: 1 rather than inflating it with unverified tiers.

    overage:
      model: restrict
      detail: >-
        Exceeding 250 profiles or 500 email sends/month restricts the ability to send
        until the next billing cycle or an upgrade. There is no automatic overage
        billing on the free tier.

paid_tiers:
  published_as_static_table: false
  mechanism: interactive calculator on https://www.klaviyo.com/pricing
  detail: >-
    Selecting a profile count and product mix produces a computed total (the page
    rendered "Total: $45 USD" with a "View breakdown" control during the 2026-08-13
    fetch). The underlying per-tier rates are not emitted into the page HTML — a
    plain-HTTP fetch of https://www.klaviyo.com/pricing returns no dollar amounts at all,
    confirming the figures are produced client-side. No public pricing or catalog API was
    found.
  named_lines_seen: [Marketing, Data + Analytics, Service, Composer, Customer Agent, Professional Services, Enterprise]
  promotions_seen_2026_08: 'Service, Composer and Customer Agent each shown at 30% off.'

api_usage_pricing:
  metered: false
  detail: >-
    Klaviyo does not bill for API calls. API access is included with the account and
    governed by rate limits (see rate-limits/klaviyo-rate-limits.yml) rather than price.
    What is billed is the underlying marketing activity — profiles stored, emails sent,
    mobile messages sent — regardless of whether it was initiated through the UI or the
    API.
  in_product_visibility: >-
    The Billing Usage API (Beta, 2026-07-15 revision) reports current-period metered
    usage against plan caps across Klaviyo products, making consumption readable
    programmatically even though price is not.
