BounceCheck is an email verification service for cold email and newsletter senders. Paste one address or upload a CSV, XLSX or TXT list, and each address comes back as valid, risky, invalid or catch-all with a 0–100 confidence score. Checks include syntax, MX records, an SMTP handshake that never sends mail to the recipient, catch-all resolution, role-account flags and detection of disposable (temporary) email domains.
Developers can verify at signup through a REST API with webhooks, or connect to Mailchimp, HubSpot, Klaviyo and other tools through Zapier.
Free tools, no account needed: SPF record generator, DMARC record generator, DNS health checker, disposable email checker and a public directory of temporary-email providers and their domains.
Plans start free (50 checks/month). Paid plans from $9.99/month for 5,000 checks.
