Bottom line
Bouncer is an email verification service priced by the credit rather than by the month, starting at $8 for 1,000 verifications, with credits that never expire and no charge for duplicates or unknown results. It covers bulk list cleaning, a real-time API, form-level blocking through Bouncer Shield, toxicity scoring and a separate Deliverability Kit. It is EU hosted and GDPR focused, which matters if data residency is on your checklist. It is not a contact finder, so it cleans lists you already have rather than building them.
Stands out for: Bouncer runs a free MCP server at https://api.usebouncer.com/mcp that connects to Claude or ChatGPT over OAuth 2.1, so a recruiter can paste a CSV into a chat and get a cleaned list back without opening the app. It exposes the same engine as the API, including single checks, batch jobs, domain checks, toxicity lists and a credit balance check, and it costs nothing beyond the credits used.
Watch out for: Entry pricing is mid-market rather than cheapest: $8 per 1,000 credits against $6.99 at EmailListVerify, with a 1,000 credit minimum purchase. The pieces people assume are included are separate lines: the Deliverability Kit is a subscription from $25/month and Bouncer Shield is priced by monthly form checks. Verification data is processed in the EU only, which is a plus for GDPR and a question to ask if your policy requires US processing.
Overview
Bouncer verifies email addresses in bulk, one at a time, or in real time through an API. Every address comes back as deliverable, risky, undeliverable or unknown, with quality flags for disposable, role-based, free provider, catch-all and full mailbox. Unknown results and duplicates are not charged, and the company publishes a deep catch-all verification claim as one of its differentiators.
Around the core verifier sit four paid or bundled extras: Bouncer Shield for blocking bad addresses at the signup form, Toxicity Check for spam traps, breached and litigator addresses scored 0 to 5, the Deliverability Kit for inbox placement, SPF, DKIM, DMARC and blocklist monitoring, and data enrichment for company information. Bouncer was founded in 2017, is based in Wroclaw, Poland, and stores data in EU AWS data centres.
Who it's for
Best for
- Recruiters and lead generation teams cleaning cold outreach lists before a send
- Teams with uneven volume that do not want a monthly seat or credit subscription
- Developers who need a documented real-time API on signup forms and sequencers
- Anyone who wants verification inside Claude or ChatGPT through an official MCP connector
Not ideal for
- Teams that need an email finder or contact database, since Bouncer only verifies addresses you supply
- Buyers who need the lowest possible cost per 1,000 at small volumes
Key features
Bulk and single verification. Upload a list or check one address, with deliverable, risky, undeliverable and unknown statuses plus disposable, role-based, free provider and catch-all flags.
Real-time API. Synchronous and asynchronous endpoints for signup forms, CRMs and sequencers, with published docs.
Bouncer Shield. No-code form protection that blocks invalid, malicious or fraudulent addresses at the point of entry, by address and by IP.
Toxicity check and Deliverability Kit. Scores addresses 0 to 5 for spam traps, breached and litigator addresses, and tests inbox placement, SPF, DKIM, DMARC and blocklists.
MCP server
First-party MCP server, documented at https://www.usebouncer.com/email-verification-mcp-server/. The endpoint is https://api.usebouncer.com/mcp, added as a custom connector in Claude or through developer mode in ChatGPT, and it authenticates with OAuth 2.1 rather than a pasted API key. It exposes the same engine as the API: verify_email, verify_emails_sync, create_batch with status and results, verify_domain, toxicity lists and check_credits. Bouncer charges no extra for the connector; verifications draw on existing credits.
