Spamdrain is a spam filtering service that sits between the sender and the user's email inbox, intercepting messages before delivery. It works by routing incoming email through Spamdrain's servers, where messages are analyzed and classified as spam or legitimate mail. Spam is quarantined or deleted, while clean messages are forwarded to the user's regular inbox. The service is designed to be compatible with any email provider, email client, or device, requiring no software installation on the user's end. Users can manage multiple email accounts from a single Spamdrain account and review quarantined messages through a web interface. The service offers both individual and business plans, with business plans supporting multiple users and email addresses. Spamdrain also provides a feature to block specific senders and domains. The filtering process is described as automatic and continuous, with users able to adjust sensitivity settings and whitelist trusted senders.
