Sending to invalid addresses drives up bounces, and high bounce rates damage your sending reputation — and can get a domain auto-paused. Verifying addresses up front prevents that.
When you import, you can run email verification to check addresses before they enter your database. Verified results let you avoid sending to risky or undeliverable addresses.
Combine verification with the platform's other safeguards: keep lists clean, let new domains warm up, and watch your Deliverability stats. Together these keep bounce rates low and your domains healthy. Verification is optional per import, so you can apply it to riskier or older lists where it matters most.
