How to clean MailerLite data with BounceBlock
Why MailerLite subscribers need verifying
Imported and form-sourced subscribers bring in typo'd and disposable addresses that erode open rates over time.
Verifying email, phone and company in one pass — flat-priced, not per-verification credits — keeps your MailerLite subscribers deliverable and your reporting honest. A native sync is on the roadmap; today it's a quick CSV round-trip or a real-time API check.
