Reviews
what people actually sayThe Klaviyo WordPress plugin is broadly regarded as unreliable and feature-incomplete, with users citing persistent bugs, performance issues, and poor support, making it difficult to recommend despite Klaviyo's strengths as an email platform overall.
What people like
- +Klaviyo as an email service provider offers better analytics and overall capability compared to some competitors like Omnisend
- +Basic WooCommerce integration functions adequately for simple use cases
Common complaints
- −Plugin causes significant website performance and speed degradation×2
- −Forms randomly disappear from the website, requiring a full plugin reinstall to restore×2
- −Plugin switches itself off unexpectedly, disabling email flows; acknowledged by support as a known but unfixed bug×2
- −Compatibility issues with the latest WordPress version and fatal errors triggered by plugin updates×2
- −No support for automated unique/dynamic discount codes, considered a significant missing feature×2
- −WooCommerce integration lacks depth: missing refund amount data, failed order events, and granular order metadata
- −No built-in support for 'Viewed Product' / Browse Abandonment events — requires manual theme file edits
- −No ability to customize which order statuses count as 'fulfilled'
- −No way to hook into or extend the default placed order event with custom metadata
- −Embed/form code does not render correctly on pages — displays raw code instead of the form
- −Connection/authentication is unreliable; no API key fallback when OAuth-style connection fails
- −Support is slow, unhelpful, and relies on copy-paste responses, with agents lacking product knowledge×3
- −Accounts reportedly disabled without clear reason or adequate explanation from support×2
- −Excessive marketing spam emails sent after account registration
- −Plugin described as poorly coded, with server providers reportedly auto-disabling it due to bad code×2
