Does Marketo verify emails?

Marketo does not include built-in email verification. It tracks bounces after sending, but it won't proactively tell you which addresses are invalid before you hit send.

How do I export leads from Marketo?

Go to Database, open a Smart List or static list, select the leads you want, and choose Export from the List Actions dropdown. Save as CSV with the email column included.

How often should I verify my Marketo database?

Every 3-6 months or before major campaign sends. Enterprise databases decay quickly as contacts change jobs and email addresses go stale.

Will verification affect my Marketo lead scores?

Removing invalid leads improves scoring accuracy. Your models will reflect genuine engagement signals instead of being diluted by undeliverable addresses.

Can I automate verification with Marketo?

You can use Truelist's API with Marketo webhooks to verify new leads as they enter your database, keeping your list clean automatically.

Why verify your Marketo email list

Marketo charges based on the size of your lead database, so invalid emails directly inflate your bill. High bounce rates from unchecked lists also hurt your sender score and can trigger Marketo's own deliverability warnings. Verifying before major campaigns keeps costs down and deliverability high.

savings Lower Database Costs: Marketo pricing scales with your lead count. Removing invalid records cuts your tier and saves money every billing cycle.
shield Protect Sender Score: Enterprise sending volumes amplify bounce damage. Clean lists prevent reputation hits that affect every campaign you send.
analytics Reliable Lead Scoring: Invalid contacts skew engagement metrics and lead scores. Verified data means your scoring models reflect real buyer intent.
bolt Faster Smart List Processing: Smaller, cleaner databases mean Smart Lists and batch campaigns process faster with fewer wasted computations.
