Does Mailjet verify emails?

Mailjet does not include built-in email verification. It tracks bounces after sending but cannot proactively identify invalid addresses before you send. Truelist verifies upfront.

How do I export contacts from Mailjet?

Navigate to Contacts > Contact Lists, select the list, open the Manage Contacts dropdown, and click Export to download a CSV.

Can bad marketing lists affect my Mailjet transactional email?

Yes. Mailjet uses shared reputation infrastructure. High bounce rates from marketing campaigns can lower your sender score and impact transactional email delivery.

Is Truelist cheaper than Mailjet for verification?

Mailjet does not offer email verification. Truelist provides dedicated verification at pay-as-you-go rates, and the reduction in wasted Mailjet sends typically offsets the cost.

savings Optimize Send Volume Pricing: Mailjet charges by emails sent. Removing invalid addresses from your lists means fewer wasted sends and lower monthly bills.
settings Reliable API Sends: If you use Mailjet's API for programmatic sending, verification ensures your contact data is clean before it enters the pipeline.
