ListBouncer Reviews & Product Details

ListBouncer is a pay-as-you-go email verification and list cleaning service for newsletter writers, online stores and small businesses. Upload a CSV of email addresses and you get back a clean list, a health grade, and a receipt of everything that was removed and why. More than 170 customers have cleaned over 260 lists with it, and over 200,000 addresses have been checked. How it works: Export your contacts as a CSV from MailPoet, Mailchimp, Klaviyo or any other email platform and upload it. There are no accounts to connect and no API to set up. ListBouncer checks every address and sorts it into one of five groups: Safe, Major provider, Risky, Will bounce or Unknown. Each address comes with the reason for its result. When the list is ready, we email you. What it checks: Syntax, domain and mail server (MX) records, about 3,500 known disposable email domains, shared inboxes like info@ and sales@, catch-all domains, and a live SMTP check against the mailbox itself. Yahoo, Outlook, Hotmail and AOL don't allow anyone to confirm a single mailbox, so ListBouncer puts those addresses in their own Major provider group instead of guessing. What you get: A before-and-after list health grade from A to F, a removal receipt, typo suggestions such as gmial.com to gmail.com, a breakdown of bad signups by source, an estimate of what the clean saves on your email platform bill, and a reminder when it's time to clean again. You choose whether to keep borderline addresses, then download a file formatted for MailPoet, Mailchimp or Klaviyo, or a standard CSV. Pricing: No subscription. Buy a credit pack once: 2,000 addresses for $9, 5,000 for $19, 10,000 for $35, 25,000 for $69 or 50,000 for $119.
