Does Klaviyo verify emails on its own?

Klaviyo tracks bounces and suppresses hard-bounced addresses after sending, but it does not proactively verify whether emails are deliverable. Truelist performs full SMTP-level verification before you send.

How do I connect Klaviyo to Truelist?

Click the "Connect Klaviyo" button in your Truelist dashboard. You will authorize via OAuth and your profiles sync automatically. No API keys required.

Will verifying profiles lower my Klaviyo bill?

Yes. Klaviyo charges by active profiles. Removing invalid emails reduces your profile count and can move you to a lower pricing tier.

How often should I verify my Klaviyo profiles?

We recommend verifying quarterly or before major campaigns like Black Friday. E-commerce lists can decay quickly as customers change email providers.
