Personalization Merge Tags
Klaviyo uses specific Django-style merge tags for personalization, like `{{ first_name|default:'Friend' }}`. Our tool checks for these to ensure your personalization will work correctly.
Klaviyo Unsubscribe Tag
The most reliable way to create a compliant unsubscribe link in Klaviyo is by using the `{% unsubscribe %}` tag. This tag generates a unique link for each recipient.
View in Browser Link
To allow users to view the email in a web browser, Klaviyo uses the `{% web_view_url %}` tag. This is the recommended method over a static link.
CSS Inlining
Klaviyo automatically inlines CSS from `<style>` blocks in your email's `<head>`. Our tool recommends consolidating CSS into a style block, which is a best practice that works perfectly with this feature.
Section-Based Editing
For users of Klaviyo's visual editor, our AI can rewrite content section-by-section. This allows you to improve the copy for one block at a time without altering the entire template.
No Scripts or Forms
Like all major email clients, Klaviyo strips out any `<script>`, `<iframe>`, or `<form>` tags for security reasons. Our analysis flags these as critical errors.
