Null Bounce vs Validzilla Detailed comparison features, price

Null Bounce

Null Bounce provides an email verification service designed to enhance email marketing effectiveness by cleaning email lists and minimizing bounce rates. Users can easily start by registering for a free account, which includes 100 complimentary email verifications. The platform accepts email lists uploaded in standard CSV and TXT formats. Once the verification process is complete, users are notified via email and can download their cleaned list, ensuring higher deliverability for future campaigns.

The service employs a comprehensive validation process to ensure list accuracy. This includes checking for syntax errors, identifying and removing disposable or temporary email addresses, and detecting catch-all domains that inaccurately report all emails as valid. Null Bounce also identifies duplicate emails (charging only once per unique email), flags role-based and free provider addresses, utilizes anti-greylisting techniques to minimize uncertain results, performs Mail Transfer Agent (MTA) validation for MX records, and identifies hard bounces. Notably, users are not charged for emails that result in an 'unknown' status.

With affordable pricing, rollover credits, and opportunities to earn free verifications, Validzilla provides a cost-effective way for businesses to maintain high-quality outreach efforts.
