Bouncer

What Bouncer is

Bouncer is an email verification service for checking mailing lists and finding addresses that may bounce before messages are sent. Each result reports deliverability status and a reason, alongside details such as score, toxicity, provider, role and disposable or full-mailbox flags. The website supports single-address checks, and new accounts receive 100 verifications free. For larger workloads, its API offers synchronous, asynchronous, real-time signup and batch checks. Bouncer Shield checks addresses during form entry and can block invalid, malicious or fraudulent addresses based on email or IP. Other listed products include Toxicity Check, Deliverability Kit, company data enrichment and email engagement insights. Integrations include HubSpot, Klaviyo, Mailchimp, Make and Pipedrive. Bouncer says uploaded emails are anonymized throughout its system and data is stored in EU AWS data centres; it also states GDPR compliance and SOC 2 certification. Email verification costs $8, paid once, billed $8 for 1,000 credits, which do not expire. Purchases start at 1,000 credits. The service is available through web and API, with support by chat, email and video call.
