Klaviyo
Klaviyo is the e-commerce anchor of our catalog: an email platform built around online-store data, spanning e-commerce email, email marketing, and marketing automation. We confirmed klaviyo.com serves the platform directly in August 2026 (the site geo-served a localized variant on the same domain).
Its pricing page offered an exact match for our normalization volume: the Email plan costs $30/month at 1,000 profiles with 10,000 sends, billed monthly only. A free plan covers up to 250 profiles and 500 emails per month. Pricing checked 19 August 2026. Klaviyo's curve is the steepest in our marketing capture: at 1,000 profiles its $30/month sits mid-pack, but at 50,000 profiles the same plan costs $720/month — the most expensive functional tier we recorded at that volume (multi-volume capture, 21 August 2026).
Deliverability: not yet tested. No inbox-placement score is shown until our seed-list cycle runs. The measurement protocol lives at how we test, and results land in the email deliverability ranking.

What others say about deliverability
Independent Klaviyo-audit consultancy's guide on why Klaviyo emails land in spam: default shared infrastructure pools 'your sender reputation with thousands of other brands,' a dedicated sending domain takes 60-90 days to build reputation, and exceeding Gmail's complaint threshold routes all your mail to spam; targets 96%+ inbox placement, <0.08% complaints, <2% bounces.
Deliverability-tool vendor's analysis noting Klaviyo 'does not report inbox versus spam folder placement' (only acceptance and engagement), so senders must run external inbox-placement monitoring and rigorous list hygiene as volume scales.
Rates Klaviyo's deliverability infrastructure 'solid' (all-plan SPF/DKIM, monitored shared IP pools, Smart Sending, dedicated IPs on request) but flags the biggest risk as self-inflicted list bloat — the Feb 2025 billing change charging for unsubscribed profiles discourages list cleaning, which harms sender reputation; no numeric inbox-rate data given.
A practitioner reports Klaviyo 'put us on a shared IP with not-so-good senders, so my emails were going to spam folder,' dropping their open rate from 40-50% (prior provider) to 15% after two campaigns.

How much does Klaviyo cost?
Paid Klaviyo plans start at $30/mo (Email tier), prices as shown by the vendor, last checked 19 August 2026. That tier already includes automation, API access and branding removal.
Does Klaviyo document its deliverability capabilities?
Klaviyo documents 15 of the 17 deliverability capabilities we audit every vendor for (authentication help, IP management, list hygiene, reputation tooling).

What do users say about Klaviyo?

Has Klaviyo's deliverability been tested by InboxRatio?
Not yet — Klaviyo is in the queue for Cycle 0, our first seed-list test cycle across the whole catalog. We publish measured inbox-placement results only after a completed cycle, so this profile carries no Deliverability Score until then. How we test.
What are the main Klaviyo alternatives?
From our catalog, the closest alternatives are Mailchimp, Omnisend and Drip — services sharing Klaviyo's primary category (e-commerce email), selected by a neutral catalog rule, never hand-picked.
