About Crackbounce
Crackbounce is an online email verification service for marketers and developers who want to keep bounce rates low. Before you send a campaign, it checks each address against syntax rules, domain verification and risk detection so invalid contacts are removed and your sending domain stays healthy.
You can upload a large list for bulk cleaning, or call an API to validate addresses in real time from registration forms and apps. The service identifies temporary and burner addresses to prevent fake sign-ups, and provides analytics and quality reports on verification activity. The site also mentions multi-channel marketing features across email, SMS and social media.
Crackbounce is a hosted commercial product. Its homepage promotes lifetime access with no monthly fees and a free trial, with the details on its pricing page.
