Bouncer

What Bouncer is

Bouncer is an email verification service for checking mailing lists and identifying addresses likely to bounce before sending. Its results report deliverability status and a reason, alongside address details such as score, toxicity, provider, role, and disposable or full-mailbox flags. The site offers single-address verification, and new accounts get 100 verifications free.

For larger workloads, the email verification API provides synchronous and asynchronous endpoints, real-time signup checks, and batch endpoints. Bouncer Shield checks addresses as people enter them and can block invalid, malicious, or fraudulent addresses based on email address 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 it anonymizes uploaded emails throughout its system and stores data in EU AWS data centres; it also states GDPR compliance and SOC 2 certification. The service is available on the web and by API, with support by chat, email, and video call. Email verification costs $8 for 1,000 credits, which do not expire, and purchases start at 1,000 credits.

Who it suits

Bouncer suits marketers, lead generation teams, agencies, SaaS companies, enterprises, and engineers who need to check email addresses before sending or during signup. Its API and form checks also suit teams handling verification in their own workflows.

Limits
