Across Klaviyo workspaces, roughly 16% of unverified Email ($email) records are invalid, deactivated, disposable, or duplicate contacts that inflate your Klaviyo invoice every month:
Go to Klaviyo Audience → Lists & Segments → Export Segment to CSV.
KaijuVerifier flags 1,000,000+ disposable coupon-burner domains and suggests automatic fixes for checkout typos like @gmial.com and @hotmial.com.
Upload the invalid CSV to Klaviyo Profiles → Suppressed Profiles. Suppressed profiles are 100% free in Klaviyo and never billed!

Yes. Our pre-DNS consumer typo detector catches 36 common mobile keyboard typos (like @gmial.com, @yaho.com, @iclod.com) and outputs the corrected address so you can recover lost order and cart emails.
For Shopify, WooCommerce, and Magento brands running Klaviyo, active profile bloat is a double tax: you pay higher monthly Klaviyo tier invoices for unengaged or fake spin-to-win coupon emails, AND high bounce/unengaged ratios push your Black Friday / Cyber Monday flows from Gmail Primary into the Promotions or Spam tab.
Export your Klaviyo 180-day unengaged and sunset segments as a CSV or Multi-Sheet .XLSX workbook, verify them through KaijuVerifier at $19 per 10,000 profiles, and push invalid/disposable profiles to Klaviyo’s /api/profile-suppression-bulk-create-jobs endpoint to immediately cut your monthly Klaviyo bill and restore open rates.
