Why Email Verification Matters

1. Protect acquisition spend

• Fake signups distort CAC/ROI, especially on paid campaigns.
• By filtering burner domains, automation workflows only nurture real users.

2. Shield revenue and promotions

• Coupons, referral credits, and trials are prime targets for disposable inbox abuse.
• TrueMail’s signals let you add extra verification for “high-risk but possibly real” users instead of blunt rejections.

3. Improve deliverability and compliance

• High bounce rates tank ESP reputation and can land you on blacklists.
• Regulations such as GDPR/CCPA expect clear provenance. Clean lists make DSARs and deletions painless.

4. Enhance product experience

• Smart typo correction (gnail.com → gmail.com) keeps legitimate users moving.
• Treat verification results as a trust score to unlock progressive authorization for good users.
