Hi ​@nynketomorrowmen11 - You’re not alone, Klaviyo’s Google Ads integration can produce low match rates, and it typically comes down to how limited the synced data is. Here is why this can happen:

• Klaviyo only syncs email addresses by default. Google Ads performs best when it has multiple identifiers (like phone number, name, ZIP, country).
• Emails alone, especially business or inactive emails often won’t match well.
• No enhanced match logic: Klaviyo doesn’t pre-hash or normalize data the same way as manual uploads do, so Google has less to work with.

What You Can Do to Improve Match Rate:

1. Manually export your Klaviyo list, then upload it into Google Ads as a Customer Match audience with as many fields as possible:

• Email
• Phone number
• First name / Last name
• Country / ZIP

2. Focus on personal emails (e.g., @gmail.com), create a Klaviyo segment filtered by email domains to test match rate separately.

3. Clean and format your list before upload:

• Lowercase emails
• Add country codes to phone numbers
• Remove invalid characters

4. Use Enhanced Conversions in Google Ads alongside your audience targeting, this improves match quality using site visitor data.
