The Hidden Cost of Dirty Email Lists

Low-quality emails don't just hurt your metrics—they damage your sender reputation and cost real money in wasted credits.

Poor Deliverability Rates

Hard bounces and spam complaints damage your sender reputation with ESPs like SendGrid and Mailchimp.

15-30% bounce rate

Temporary Email Pollution

Users sign up with disposable emails to grab lead magnets, then never engage with future campaigns.

8-12% temp emails

Wasted Marketing Spend

Every temporary or invalid email costs you send credits and inflates your subscriber count with dead weight.

$200-500/mo lost
