NeverBounce vs Scrubby Comparison: Everything You Need to Know Before Choosing

NeverBounce is an email verification service, now part of ZoomInfo, that helps organisations keep their mailing lists clean and improve deliverability. Invalid, mistyped, disposable and inactive addresses cause hard bounces, which damage sender reputation, lead to messages being filtered as spam and waste spending on email platforms that charge by contact volume. NeverBounce addresses this by checking addresses before messages are sent, testing syntax, domain configuration and mailbox status through a multi-step verification process and classifying each address as valid, invalid, disposable, catch-all or unknown. The core approach is to provide verification both in bulk, for cleaning existing lists, and in real time, for validating addresses at the point of capture, so that bad data is removed and prevented from entering systems in the first place. Results are presented through a simplified dashboard that tracks job progress as lists are processed. Cleaner lists help organisations protect sender reputation, lower bounce rates and reduce spending on undeliverable contacts. Bulk cleaning allows users to upload CSV or spreadsheet files, or to connect directly to email marketing and CRM platforms, and receive cleaned lists with detailed result codes. Automated sync features can re-verify lists over time as addresses decay. The real-time API and JavaScript widget validate addresses on sign-up forms, checkout pages and lead capture tools, rejecting invalid entries instantly. NeverBounce offers a large number of integrations, including Mailchimp, HubSpot, Salesforce, ActiveCampaign, Constant Contact, Marketo and Zapier, as well as client libraries for common programming languages. It is a cloud-based service that emphasises data security and does not retain customer lists beyond what processing requires. Users include email marketers, agencies, e-commerce companies, SaaS businesses and sales teams. Pricing starts from around USD 0.01 per verification on a pay-as-you-go basis, a free trial is available, and a free version with limited checks is also offered.
