What is Bouncer?
Bouncer is an email verification platform that ensures your messages reach real inboxes. Every bounced email hurts your sender reputation, and enough bad addresses can get your domain blacklisted entirely. Bouncer solves this by validating email addresses before you send, keeping your lists clean and your reputation intact.
The platform offers impressive accuracy with less than 2% unknown results—among the best in the industry. Whether you're cleaning an existing database of millions or validating signups in real-time, Bouncer handles email verification at any scale while maintaining GDPR compliance with EU-hosted infrastructure.
Verify & Clean Your Email ListsKey Features
Batch Email Verification
Upload your email lists and let Bouncer analyze each address. The system checks for syntax errors, domain validity, mailbox existence, and deliverability signals. Results categorize emails as deliverable, risky, or undeliverable, giving you clear guidance on which addresses to keep.
Processing happens quickly even for large lists. The platform handles millions of verifications efficiently, making it practical for enterprise-scale database cleaning.
Real-Time API Verification
Integrate Bouncer's API into your signup forms, CRM, or marketing automation. Validate emails the moment they're entered, preventing bad data from ever reaching your database. The API responds in milliseconds, ensuring no friction in user experience.
Bouncer Shield
Shield goes beyond basic verification to protect forms from sophisticated threats. It blocks disposable email addresses, spam traps, and known complainers before they enter your system. This proactive protection prevents problems rather than cleaning them up later.
Toxicity Check
Not all valid emails are safe to email. Toxicity Check identifies addresses that could harm your sender reputation—spam traps, breached emails, serial complainers, and abuse addresses. Removing these high-risk contacts protects your deliverability.
Deliverability Kit
Test whether your emails actually reach the inbox across major providers like Gmail, Outlook, and Yahoo. The kit also verifies your authentication setup (SPF, DKIM, DMARC) to ensure technical configuration supports deliverability.
Who Uses Bouncer?
E-commerce and Retail
Online retailers verify customer email addresses at checkout and during account creation. Clean email lists ensure promotional campaigns reach buyers, abandoned cart emails drive recovery, and transactional messages confirm orders reliably.
SaaS and Technology Companies
Software companies integrate Bouncer's API into signup flows to capture only legitimate users. This prevents fake accounts from skewing metrics, reduces onboarding waste, and ensures trial users receive critical activation emails.
Marketing Agencies
Agencies managing multiple client email lists use Bouncer to maintain quality across accounts. Regular verification before campaigns protects client sender reputations and maximizes engagement rates for measurable results.
Lead Generation Services
Companies building and selling lead lists verify addresses before delivery to clients. High-quality, verified leads command premium prices and build long-term client relationships based on data accuracy.

Tips for Success
Verify your entire email list before launching major campaigns—even addresses that worked previously can become invalid over time. Schedule regular verification cycles, ideally monthly for active lists or quarterly for dormant databases.
Integrate real-time API verification at every data entry point: signup forms, checkout pages, contact forms, and CRM imports. Preventing bad data from entering is more efficient than cleaning it later.
Pay attention to toxicity scores, not just deliverability status. An email might be technically valid but could still harm your reputation if it belongs to a known complainer or spam trap.
