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.

Key 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.

Bouncer Pricing

Bouncer uses a flexible credit-based system. You purchase credits and use them as needed—no monthly commitments or wasted allocations. A free tier provides initial credits to test the platform before purchasing.

Volume discounts make large-scale verification affordable. Enterprise customers can arrange custom pricing and dedicated support for high-volume needs.

Real-World Use Cases

Marketing teams use Bouncer to clean lists before major campaigns. Sending to verified addresses dramatically improves open rates, click rates, and ultimately conversions. The investment in verification pays back through better engagement and protected sender reputation.

SaaS companies integrate the API into signup flows to ensure quality leads from day one. Rather than accumulating fake signups that skew metrics and waste onboarding resources, they capture only legitimate users.

Agencies managing multiple client lists use Bouncer to maintain quality across accounts. The platform's accuracy and ease of use make it practical to verify regularly rather than only during crises.

Both offer comprehensive verification, but Bouncer's pricing tends to be more accessible for smaller volumes. ZeroBounce includes AI-powered scoring that some users prefer, while Bouncer excels in accuracy and EU compliance.

Bouncer vs NeverBounce

NeverBounce offers similar core functionality with strong integrations. Bouncer differentiates through Shield's form protection and the Deliverability Kit. Choose based on whether you need more preventive or diagnostic tools.

Bouncer vs Hunter

Hunter focuses on email finding while Bouncer focuses on verification. Many users employ both—Hunter to discover emails, Bouncer to verify them before outreach.
